Volume 15 I s sue 5 2 012
the international magazine for the aquaculture feed industry
The use of algae in fish feeds as alternatives to fishmeal
Gustor Aqua and Ecobiol Aqua:– enhancing digestion in a different manner
Fishmeal & fish oil– and its role in sustainable
aquaculture
Options and challenges of alternative protein and energy
As feed prices soar and formulation moves towards sustainability, aquaculture producers must think differently to stay on the menu.
In all phases of the fish’s life, proper nutrition will improve health. With decades of dedicated research, the “Alltech Aqua Advantage” programme responds to the challenges of today’s aquaculture producers
through nutritional innovation, addressing issues such as growth and performance, feed efficiency, flesh quality and immunity.
So, when asked who cares about your profitability? Remember
WHO CARES...…If profits in the aquaculture industry are as appetising as a salmon dinner?

Total global fish produc-tion, including bothwild capture fish andaquaculture, reached an
all-time high of 154 million tonsin2011,andaquaculture is set totop 60 percent of production by2020, according to new researchconducted by the WorldwatchInstitute (www.worldwatch.org)for itsVital Signs Online service.Wild capture was 90.4 milliontons in 2011, up 2 percent from2010.Aquaculture, incontrast,hasbeen expanding steadily for thelast 25 years and saw a rise of6.2 percent in 2011,write reportauthors Danielle Nierenberg andKatieSpoden.
"Growth in fish farming canbe a double-edged sword," saidNierenberg,co-authorofthereportand Director of Worldwatch'sNourishing the Planet project."Despite itspotential to affordablyfeed an ever-growing global pop-ulation, it can also contribute toproblems of habitat destruction,wastedisposal, invasionsof exoticspecies andpathogens, anddeple-tionofwildfishstock."
Humans ate130.8million tonsof fish in 2011.The remaining23.2million tons of fishwent tonon-foodusessuchasfishmeal,fishoil, culture, bait, andpharmaceuti-cals.Thehumanconsumptionfigurehasincreased14.4percentoverthelast fiveyears.Andconsumptionoffarmed fishhas risen tenfold since1970, at an annual averageof 6.6percent per year.Asia consumestwo thirds of the fish caught orgrownforconsumption.
The fish sector is a source ofincomeandsustenanceformillionsof people worldwide.Accordingto theUNFood andAgricultureOrganization, foreveryone job inthe fish sector, three to four addi-tional jobs are produced in sec-ondary activities, such as fishprocessing,marketing,maintenanceof fishing equipment, and otherrelated industries.Andonaverageeach person working in the fishsector is financially responsible forthreedependents.

The tr ial results presentedshowedthatdependingonfarmingconditions, 20 to 50 percentfewer deformities occurred infishlarvaefedfeed,containingthefeed additive, Pediococcus acidi-lactici MA18/5M.This probioticstrain, authorised in the EU foruse in certain aquaculture appli-cations and species since 2009,is routinely added to the rearingwater in the production of livepreyforfishlarvae.
However,asanadditionviadryfeed it seems to be more effi-cient in delivering the probioticbacteria to the gut of the fishlarvae. Since 2009, BioMar hasincluded Pediococcus acidilacticiMA18/5MaspartoftheINICIOPlus range of star ter feeds forsalmonids and has developed aspecial process to add the heatsensitive live bacteria in dr yfeed.
‘We still have to await EUapproval before we can applythis knowledge and launch an

Ithas been a long andr i gorous process ,but good news ise x p e c t e d s o o n ’ ,says Michel Autin,Technical Director atBioMar West Med.He continues ‘I amvery optimistic thatthe approval will beobtained as resultsfrom smaller scalel abor ator y basedtr ia l s were repl i -cated in larger scalecommercial hatch-erieswithsimilarorevenbettereffectsondeformities’.
TheEU-approvalof theuseofthe probiotic strain, Pediococcusacidilactici CNCM MA18/5M, infeed for salmonids obtained in2009 was based on a well-doc-umented demonstration of thereduction of vertebral deform-ities in salmonids. However forthis approval to be extended toother species, additional doc-umentation needed to be pre-sentedtotheEFSA,andthiswasdonelastyear.

Fishmeal is very extensively usedin feeds for fish as well as otheranimals. A recent global surveyestimatedaquacultureconsumption
of fishmeal at 3724 thousand tonnes in2006 (Tacon and Metian 2008). Now it isbecomingincreasinglyevidentthatsuchcon-tinuedexploitationof this natural resourcewillultimatelybecomebothenvironmentallyandeconomicallyunsustainable.
Any satisfactory alternative feed ingre-dients must be able to supply compara-ble nutritional value at competitive cost.Conventional land-based crops, especiallygrains and oilseeds, have been favouredalternativesduetotheirlowcosts,andhaveproved successful for some applicationswhen they were used as substitutes fora portion of the fishmeal. But even whenthese plant-based substitutescan support goodgrowth theycancausesignificantchangesinthenutritionalqualityofthefishproduced.
Why algae?Thereadermaywonderwhy
algae, includingbothmacroalgae(‘seaweeds’)andmicroalgae(e.g.phytoplankton), and which arepopularly thought of as ‘plants’,would be good candidates toserve as alternatives to fishmealin fish feeds. One fundamentalconsideration is that algae arethe base of the aquatic foodchains that produce the foodresources that fish are adapt-ed to consume. But often it isnot appreciated that the bio-chemical diversity among differ-ent algae can be vastly greaterthan among land plants, evenwhen ‘Blue-Green Algae’ (e.g.Spirulina), more properly calledCyanobacteria, are excluded
from consideration. This reflects the veryearlyevolutionarydivergenceofdifferentalgalgroupsinthehistoryoflifeonearth.Onlyoneof the many algal groups, the Green Algae,produced a line of descent that eventuallygaverisetoallthelandplants.Thereforeitcanbedifficulttomakemeaningfulgeneralisationsabout the nutritional valueof this extremelydiversegroupoforganisms;ratheritisneces-sary to consider the particular qualities ofspecificalgae.
Protein and amino acidsFishmeal is so widely used in feeds
largely thanks to its substantial contentof high-quality proteins, containing all theessential aminoacids.Acritical shortcom-ing of the crop plant proteins commonlyusedinfishfeedsisthattheyaredeficientin certain amino acids such as lysine,
methionine, threonine, and tryptophan (Liet al.2009),whereasanalysesoftheaminoacid content of numerous algae havefound that although there is significantvariation, they generally contain all theessentialaminoacids.Forexample,surveysof 19 tropical seaweeds (Lourenço et al.2002) and 34 edible seaweed products(Dawczynski et al. 2007) found that allspeciesanalysedcontainedalltheessentialaminoacids,andthesefindingsareconsist-ent with other seaweed analyses (Roselland Srivastava 1985, Wong and Peter2000,Ortizet al.2006).
Analysesofmicroalgaehave foundsimilarhigh contents of essential amino acids, asexemplified by a comprehensive study of40 species of microalgae from seven algalclassesthatfoundthat,“Allspecieshadsimilaraminoacidcomposition,andwererichinthe
essentialaminoacids”(Brownet al.1997).
TaurineOne often-overlooked
nutrient is the non-proteinsulphonic acid taurine, whichis sometimes lumped withamino acids in discussionsof nutrition. Taurine is usu-ally an essential nutrient forcarnivorousanimals, includingsomefish,but it isnot foundin any land plants. However,although taurine has beenmuch less often investigat-ed than amino acids, it hasbeen reported in significantquantities inmacroalgaesuchas Laminaria, Undaria, andPorphyra (Dawczynski et al.2007, Murata and Nakazoe2001) as well as certainmicroalgae, for example thegreen flagellate Tetraselmis(Al-Amoudia and Flynn1989),theredunicellularalga

LipidsIn addition to its high content of high-
quality protein, fishmeal provides lipids richin ‘PUFAs’, or polyunsaturated omega-3 andomega-6 fatty acids. These are the ‘fish oil’lipidsthathavebecomehighlyprizedfortheircontributiontogoodcardiovascularhealth inhumans.But it isnotalwaysappreciatedthatalgaeatthebaseoftheaquaticfoodchaininfactoriginatethese‘fishoil’ fattyacids.Thesedesirable algal fatty acids are passed up thefoodchaintofish,andtheyareindeedessen-tialnutrientsformanyfish.
Algae have been recognised as anobvious alternative source of these ‘fishoil’ fatty acids for use in fish feeds (Milleret al. 2008), especially eicosapentaenoic

Use of algae in aquacultureMany different algae already play a vital
role in aquaculture. It is widely known thatthe addition of microalgae to larval fish
culture tanks confers a number of benefits,suchaspreventingbumpingagainstthewallsofthetanks(BattagleneandCobcroft2007),enhancing predation on zooplankton (Rochaet al.2008),enhancingthenutritionalvalueofzooplankton (Van Der Meeren et al. 2007),aswellas improving larvaldigestive(Cahuet al.1998)andimmune(Spolaoreaet al.2006)functions.
Furthermore, it has also been shownthat larvae of some fishes benefit greatlyby direct ingestion of microalgae (Reitanet al. 1997). One study has even shownthatthat livezooplanktoncouldbeelimi-natedfromthelarvaldietofRedDrumifmicroalgaewere fed alongwith a formu-lated microparticulate diet (Lazo et al.).
It is not surprising that the biochemicalcompositions of certain marine micro-algae are well-matched to the nutritionalrequirements some marine fish. Larvalfeedsareprobablydeservingof themostattentionineffortstodiscoverhowalgaecan best be used in fish feeds, becausemicroalgae are a natural component ofthe diet of many larval fish, either con-sumed directly or acquired from the gutcontents of prey species such as rotifersandcopepods.Existingprotocolsthatuse
microalgae to improve the PUFA profileof live prey (Table 1) demonstrate howeffectively an algal feed can enhance thenutritionalvalueoftheselivefeeds.
Use of algae in formulated fish feeds
Variousspeciesofmacroalgaeandmicro-algae have been incorporated into fish feedformulations to assess their nutritional value,andmanyhavebeenshowntobebeneficial:ChlorellaorScenedesmus fedtoTilapia(Tartielet al. 2008);Chlorella fed to Korean rockfish(Baiet al. 2001);Undaria orAscophyllum fedtoSeaBream(Yoneet al.1986);Ascophyllum,Porphyra,Spirulina,orUlva fed toSeaBream(Mustafa and Nakagawa 1995); Gracilaria or
Ulva fed to European Sea Bass (Valenteet al. 2006); Ulva fed to Striped Mullet(Wassefet al. 2001);Ulva orPterocladia fed to Gilthead Sea Bream (Wassef et al.2005);Porphyra,oraNannochloropsis-IsochrysiscombinationfedtoAtlanticCod(Walkeret al.2009,2010).Unfortunately,it has rarely been possible to determinethe particular nutritional factors respon-sible for these beneficial effects, eitherbecausenoattemptwasmadetodoso,orpoordesignofthestudy.

Choosing the right algaeOften the algae chosen for fish feeding
studies appear tohavebeen selected largelyfor convenience, because they are low-costand commercially available. For example,microalgae such as Spirulina, Chlorella andDunaliella canbeproducedbylow-costopen-pond technologies and are marketed as drypowders, and their nutritional profiles are
well-documented.Macroalgaesuchasthe‘kelps’ Laminaria, Undaria, and Durvillea,and the brown rockweed Ascophyllum,occur in dense stands that can be har-vestedeconomically,andtheyhavealonghistoryofuseassourcesofiodine,assoilamendments,andanimalfeedadditivestosupplytraceelements.
In recent years there has been greatinterest in the potential of algae as abiofuel feedstock, and it has often beenproposedthattheproteinportionremain-ingafterlipidextractionmightbeauseful

The digestive system of fish andshrimp is sensitive and responsiveto a number of stressing factorsthatfrequentlyoccurandarecause
of disease and poor performance. In ordertolessenthenegativeimpactsofthoseandachieve sustainable, safe, and cost-efficientaquaculture production, nutritionists mustfocus not only on nutritional specificationsbut also on promoting digestive health.

While afirst nutritional approach is the increasinglyaccessible information on nutrient require-ments as well as on the more effective useof alternative and available ingredients, asecond approach is supplementation withnaturalgrowthpromoters(NGPs).NGPsnotonly providebenefits in termsof health andperformance but also do not bear any risk

Once in the gastrointestinal tract, sodiumbutyrate dissociates into butyric, which isstrongly lipophilic and capable to diffuseacross themembraneof gramnegativebac-teria (Gálfi and Bokori 1990), leading to adisruptionofthemetabolicprocessesandtheconsequent bacterial death.

elucidating greater epithelial cell proliferationwith the administration of sodium butyratewhen compared to other salts as sodiumacetate and sodium propionate (Sakata andTamata1978a,1979;Sakata1987).
In a study conducted in broilers, dietarysupplementation of 0.05% sodium butyrate(92%) significantly increased the length(+35.5%) and width (+ 55.7%) ofvilli at 21 and 42days, respectively(Mallo et al. 2011). As a result ofimprovedvillidevelopment,absorp-tive surface area is enlarged, lead-ing to better feed utilisation andenhanced animal health status andperformance.
Gustor Aqua has also gainedinterest due to increasing use ofplant-based diets. Several investiga-tions have reported soya-inducedenteritis in salmonids (Baeverfjordand Krogdahl 1996; Knudsen et al.2008; Krogdahl et al. 2003) andcommon carp (Urán et al. 2008).This observation has led special-ists to not include more than 5-15 percentof soya in salmon diets in order to prevententeritis.
Whencopingwiththissituation,sodiumbutyrate arises as a tool to prevent thedevelopmentofsoya-inducedenteritisandallow for a more convenient formulation
ofcommercialfeed.Thissolutionisattrib-uted to the anti-inflammatory propertiesofsodiumbutyrate,whosemodeofactionis by modification of transcription factors(NF-kB) that control the expression ofinflammatory response genes (Hamer et al.2008,LeGallet al.2009).Theresult isahealthy absorptive surface areaensuring
optimal absorption of important nutrientsaswater,mineralsorfattyacids.
In a experiment conducted with catfish(Pangasius hypohthalmus), a dietwas supple-mentedwith0.5KgGustorAqua/tonoffeedand fed twice daily during 56 days. Results(Table 1) showed significant improvements
in weight gain (+35%), specific growth rate(SGR) (+30%), feed conversion ratio (FCR)(-16%) and protein efficiency ratio (PER)(+35%) relative to the non-supplementeddiet. In a second experiment with shrimp(Penaeus monodon),adietwassupplementedwith1kgofGustorAqua/tonoffeedandfedduringtwomonths.AsshowninTable2,the
supplementationofsodiumbutyratesignificantly enhanceddigestibilityofdry matter (DMd) (+12%), crudeprotein (CPd) (+5%) and energy(Ed) (+7%), leading to numericalimprovements in weight gain, sur-vivalandFCR. Inbothexperiments,the observed positive results canbe attributed to the abovemen-tioned modes of action describedforsodiumbutyrate.

It is the combination of different modesof action what leads to host benefit whenEcobiol aqua is supplemented. B. amylolique-faciens is capable to secrete lactic acid andbarnase.Whiletheformerwillreducepatho-genic bacteria andwill be usedby beneficialbacteria such as Lactobacillus as substrate togrow,thelaterisapotentbacteriocine.Asaresult,theantimicrobialpropertiesofEcobiolAquahavebeendemonstratedagainstpatho-
gensaffectingbothcoldandwarmwateraquaticspeciessuchasAeromonas hydrophi-la, Aeromonas salmonicida,Yersinia ruckeri and Vibrio parahameolyticus (Nuez-Ortín2011).Thisinhibitoryactivity promotes optimalgut flora balance, which inturn results in less nutri-ent competition, enhanceddiseaseresistance,healthierabsorptive surface area,and consequently betternutrientutilization.
It is also known thatprobiotic bacteria canrelease extracel lularenzymes that help in thedigestion process. Thisabilitywas investigated ina recent study, in whicha total of 96 shrimp(Litopenaeus vannamei)with an average weightof 0.85 g were placed in12 aquariums and fed tosatietywith twodifferenttreatments (6 replicates/treatment); 1) unalteredcommercial shrimp feed(35% CP), and 2) com-mercialshrimpcontainingEcobiol Aqua at 2 kg/ton feed. Final biomass
was calculated as the sum of the indi-vidual weights of animals allocated ineachtreatment.AsshowninFigure1,thedifference in final biomass was numeri-cally higher until day 40, however, thisdifference became significant after day50. As the experiment was conductedin controlled conditions with absence ofpathogens, the most likely explanationforthisimprovementcanbefoundintheextracellular enzyme secretion capacityof the vegetative form of Bacillus amy-loliquefaciens. In order to investigate onthis assumption, a total of 6 shrimp per
treatment with an average weight of 6 gwere selected and fasted for 12 hours.Hepatopancreas were excised and theactivity of lipase, protease, and amylase
was analysed according to Hernández(1993), Versaw and Coupett (1989) andVega-Villsante et al. (1999), respectively.Results(Figure2)showedincreasedenzy-maticactivityinhepatopancreasafterfeedintake, suggesting enhanced digestibilityand consequently better final biomass.Secretionofamylases,cellulasesandxyla-nases has also been reported forBacillus amyloliquefaciens(Cortyl,2010).

The annual global production offishmeal and fish oil is currentlyaround fivemilliontonnesofmealand one million tonnes of oil
(Figure1),except inyearswhen the fishingintheSouthPacificisdisruptedbythewarmwatersofanElNiňo,mostrecentlyin2010.Around 22 million tonnes of raw materialis used,ofwhich approximately 75percentcomesfromwholefishand25percentfromby-products of processing fish for humanconsumption(IFFOestimates).

whilst not increasing the total amount offishmeal used, is coming through the partialreplacementoffishmealinthedietsofalmostall species (Taconet al2011,Figure3).Thisdrive to replace fishmeal is being driven bytheriseinthepriceoffishmealandimprovingnutritional knowledge, but also by concernabout the fluctuating supply due to ElNiño,etc. Of course the price of all commodi-
ties has risen steeply inrecent years and it isimportant to comparethe price of fishmealwiththealternatives.
Themostcommonlyused alternative to fish-meal is thatofsoymeal.Figure4showsthatoverthelasttwentyyearsthepriceratiooffishmealtosoymeal has increasedsignificantly, which isindicative of the factthat fishmeal is beingreduced in less criticalareas such as growerfeeds, but remains inthe more critical andlessprice-sensitiveareasof hatchery and brood-stock feeds. Fishmeal isthereforebecomingless
of a commodity and more of a strategicingredient used in places where its uniquenutritionalpropertiescangivethebestresultsandwherepriceislesscritical.

This has grown from almost nothing, tothe point where today around 25 percentof theworld’sproductionofcrude fishoil issold to this market. This has occurred at atimewhen thedemand for salmon feedhasgonefrom1.8milliontonnestonearlythreemilliontonnes.Theothercriticalfactoristhattoobtainfishoiloftherightquality(freshness,lackofoxidationproductsand levelsofEPAand DHA) the nutraceutical market pays apremiumof25-30percentoverthatforfeedoil (current price for feed-grade fish oil isapproximately$1,800/tonne).
In order to increase the production ofsalmonfeedin-linewiththemarket(aswell
as tryingtominimiseanypriceeffect) feedproducershavebeen increasinglysubstitut-ingfishoilwithvegetableoil.Thevegetableoil of choice is rapeseed (or canola) oil,which,while not having any EPAorDHA,doesatleasthaveshort-chainomega3fattyacids and fewer omega-6 fatty acids thanmost other commonly available vegetableoils such as soya oil. The point has nowbeen reached where over 50 percent ofthe added oil in salmon diets comes from
vegetable sources and this trend seemslikelytocontinue.
As salmon are poor converters of short-chained omega-3 fatty acids to long-chainfattyacidsthefattyacidprofileofthefinishedsalmon fillet is verymucha reflectionof thefattyacidprofileinthefeed.TheresultisthattheEPAandDHAcontentoffarmedsalmonis decreasing and the omega-6 content isincreasing.
This trend seems set to continue in theyearstocome.Itseemslikelythatthesalmonmarket will differentiate into ‘high EPA andDHA’ salmon demanding a price premiumandregularsalmon,which,whilestillcontain-ingsomeEPAandDHAwillhavelevelswellbelowthatfoundinwildsalmon.
Is it sustainable?One of the most often asked questions
about fishmeal and fish oil is whether ornotthepractice issustainable.This isahugetopicfordiscussionandonethatisnoteasilycovered in the last sectionofa shortarticle.Toanswer thequestiononehas togobackandlookatthesourceoftherawmaterialandlookatthematter,fisherybyfishery.Themostwidelyacceptedmeasureof sustainability fora fishery is theMarineStewardshipCouncil’s

Back in 2008 IFFO became aware thatthe fishmeal and fish oil industry needed anindependently set, third-party audited stand-ard, which could be used by a factory todemonstratetheresponsiblesourcingofrawmaterial and the responsible manufacture ofmarine ingredients. IFFO convened a multi-stakeholdertaskforceincludingfeedproduc-ers,fishfarmers,fishprocessors,retailersandenvironmentalNGOswhooverthenext18months complied the standard which waslaunchedlate2009.
The IFFO RS standard has been quicklyadopted by the industry and the point hasnowbeen reachedwhereoverone thirdofthe world production comes from certifiedfactories. The standard requires that anywhole fish must come from fisheries thataremanagedaccordingtotheFAOCodeofConductforResponsibleFisheries.Thestand-ardalsodemandsthatthefactorycandemon-strate good manufacturing practice includingfulltraceabilityfromintaketofinishedproduct.

There is a growing need for fish feedproducers and farmers to demonstrate thatall the raw materials in their feeds are beingresponsibly sourced.

Feed for fish and shrimp raised inaquaculture needs high levels ofprotein and energy. Traditionallyfeed for carnivorous or omnivo-
rous fish and for shrimp provides thesemainly as fishmeal and fish oil, whichalso contributes to the health promotingaspects of fish and shrimp in the humandiet.
Aquaculture of fed species today takes60–80percentof the fishmealand80per-cent of the fish oil produced, mainly fromtheindustrialpelagicfisheriesor,inagrow-ing trend, from the trimmings producedduring processing for human consumption.Trimmingsaredefinedasby-productswhenfish are processed for human consump-tion or if whole fish is rejected becausethequalityat the timeof landingdoesnotmeet requirements for human consump-tion. The International Fishmeal and FishOil Organisation estimates trimmings arenowusedforaround25percentoffishmealproduction.
The industry is, therefore, heavilydependent on marine resources but pro-duction from these resources cannot beincreasedsustainably,eitherforhumancon-sumptionortheindustrialfisheries.Atbest,sustainably managed fisheries will continueto yield around the current harvest of fivemillion tonnes of fishmeal and one milliontonnesoffishoil.
FeedproducerssuchasSkrettingrequiretheir marine raw material suppliers todocumentthatthefishmealandfishoilarederivedfromresponsiblymanagedandsus-tainablefisheriesanddonotincludeendan-geredspecies.Therefore,tomeetagrowingdemand for fish, aquaculture must identifyalternativestothesemarineingredients.

At the same time, a growing propor-tion of the pelagic catch, which includesthe industrial fisheries, is going to themore lucrative markets of processing forhuman consumption, as processing tech-nology improves and as new consumerswith different tastes enter the market.Simultaneously, theomega-3supplementsindustry is competing for the best qual-ity fish oils and readily outbids the feedproducers.
According to the FAO report‘The State of World Fisheries andAquaculture 2012’, aquaculture is “setto remain one of the fastest grow-ing feed sectors”. Having doubled inthe past decade to almost 60 milliontonnes globally, it is expected to growby up to 50 percent in the next. Thismakesidentifyingalternative,sustainablesources of protein and energy a majorpriority. Researchers are looking foralternatives that will provide low feedconversion ratios, maintain high fish
welfare and produce fish that are goodtoeat,both intermsofeatingexperienceand nutrition.

In2010researchersatSkrettingARCfinal-isedanewconceptknownasMicroBalance™.MicroBalance™ technology is based on theidentificationof several essentialmicro-nutri-ents in fishmeal that were shown to be thelimiting factors, not the amount of fishmeal.Supplementing the diet with the right bal-ance of essential micro-nutrients and otherfunctional micro-ingredients helped reducefishmealcontentinfishfeed.
Applying the concept enabled Skrettingcompaniestoproducecommerciallysuccess-ful feedswithas littleas15percent fishmealwithout detracting from feed performance,fish welfare or end product quality. A keyadvantage of MicroBalance is the flexibil-ity toadapt the rawmaterial combination inresponse toprices, lessening for farmers theimpactsofpricevolatility.
Today Skretting can formulate fish feedwith levels of fishmeal as low as 5–10percent. Fishmeal canbe replaced solelybyvegetablerawmaterialsorbyacombinationofvegetablerawmaterialsandnon-ruminantprocessed animal proteins (PAPs). It shouldbenotedthatPAPsarewidelyusedincoun-triesoutside theEUandprovideextremelygood quality, safe nutrition to supplementfishmeal.
Typicalexamples includebloodmealalsoknown as haemoglobin meal, poultry meal,and feather meal. PAPs were banned fromanimal feed and fish feed in the EU follow-ing the BSE crisis in the 1990s. Recently aproposal for the reintroduction of PAPs in
fish feedwasapprovedbyaqualifiedmajor-ityofEUmember states,meaning thatnon-ruminantPAPswillbeauthorisedforfishfeedfromJune1,2013.

Performance ratiosFeed conversion ratios (FCRs) have
advanced significantly over the past threedecades. InAtlanticsalmon,forexample,theFCR has decreased from 1.30 in the 1980sto slightly above 1.00 today, mainly due tothedevelopmentofhigh-nutrient-densedietsand to improvements in feed management(reducing feedwaste).This representsmoreefficient useof feed rawmaterials; especiallyasfishmealandfishoilcontentswerereducedinthesameperiod(Table1).

Production of shrimp in an indoor farming system with bioflocs
by Eric De Muylder, CreveTec, belgium
Feed management in extensive andsemi-intensive shrimp farmingsystems is not optimal to obtainthebestresults.Feedingfrequency
is limitedtofourorsixtimesperday.Thefeed isspreadoverthewholepondwhichis labor-intensive. There is an importantperiod between feeding and actual con-sumption by the shrimp, which results inleaching of important nutrients and feedquality loss. This is caused by the lowdensity of shrimp in the ponds and theshrimp can only find the fed by chemicalattraction,whichtaketime.
The feeding affects the water qualityparameters in theponds.Anoxygendrop isobservedafter feeding.Acontinuousfeedingwillresultinamorecontinuouswaterqualityand less stress for the shrimp.Often shrimpare not fed at night to avoid low oxygen,which results in important loss of potentialgrowth.
In intensive farming, the natural produc-tion of the tank is represented by bioflocs.These bioflocs directly interfere with thewater quality. Intensive farming also allowsthe mechanization of feeding without extralabor.Feedconsumptionisfacilitatedbecause
all feed pellets interact with shrimp movingaroundinthetank.
BioflocsShrimp are filter feeders and are able to
benefitfrombioflocsinthewater.In a shrimp farming system with bioflocs,
severalstrategiesarepossible.Utilizationofalowprotein feed and addition of a carbon sourceresults in very low levels of ammonia, becausetheyareassimilatedbythebioflocsandconvertedinto proteins. Typically, these systems have acarbon: nitrogen ratio of over 20. However,theconversionof ammonia andothernitrogen

One of the problems with shrimp (andothercrustacean)culture isbroodstockdietsandnutrition.
Currently, most, if not all, hatcheriesaroundtheworldusefreshorfrozen,unproc-essedmarineorganismsasfooditems.Theseincludesquid,variousmolluscs(mussels,oys-tersorclams),marinepolychates,crustaceanssuchasshrimp(Peixotoetal.,2004;Prestonetal.,2004,Comanetal.,2006)andArtemiabiomass(Anhetal.,2008,Gandyetal.,2007).Thesefeedsareusuallytoppedupwithnutri-tionaladditivessuchasvitamins,mineralsandfattyacids(Hoaetal.,2009).
Maturationdietsbasedonthecombination
of freshand frozenmarineorganismsusuallyresultsinhighreproductiveperformancesforboth domesticated and wild caught brood-stockshrimp.
However, this practice is far from ideal,exposingtheculturedanimalstoseveralmajorissues-
Biosecurity: Freshand frozen foodorgan-ismscan,potentially,becometransferringvec-torfordifferentpathogensanddiseases.Thisismore sowhencrustaceans arebeenused(Coman et al., 2006). Although, recognisedfortheircontributiontothematurationproc-ess through supplementing maturation hor-mones and other nutrients, the importationofcrustaceanssuchasArtemiawasbannedinseveralcountriesinanattempttoreducetheriskofdiseasetransfer.
Similarly, in many countries the use ofshrimp heads or shrimp meal in maturationdietswasbanned..Itisnotknownifnon-crus-taceanorganismscantransmitshrimpvirusessuch as white spot syndrome virus (WSSV)and yellow head virus (YHV) or others butduetotheirorigin,postharvestmethodsandstorage,theyareallpronetobecomeavectorforotherpathogens.
Nutritional profile: Due to the fact thatfresh/frozen foodorganismsarebeencaughtin the wild, their nutritional profile varied.Season, location, life cycle, pre and postharvesting methods can and will affect theirnutritional profile. This inconsistency in thequality and nutritional profile makes it hardto standardise protocols even within thesamecompany.Differentcountriesandevenregions within a country will have differentaccesstofresh/frozenfoodorganismsandwill
used them differently resulting in high fluc-tuation in FCRs and performances betweenfarmers, regions and countries culturing thesamespecies.
Waterquality: Inmanycaseshighwaterflow is needed following feeding of fresh/frozen foodorganisms. Inmanycasesdaily(orevenfewtimesduringtheday)siphon-ing is essential to keep goodwater qualityand tank hygiene. This is obviously labour-intensive task that might also affect thebroodanimals.
Domestication: It is commonly acceptedthatwildbroodstockshrimpneeds fresh/fro-zen food organisms. For example, Conan etal.,2006 raised thehypotheseiswhether theremoval of crustacean component from thematurationdietfordomesticatedP.monodonbroodstock has contributed to the brood-stocklowperformances.
Consideringthecostofbroodstock(espe-cially ‘SPF’), these are serious risks and inmany cases resulting in high mortality and/orreducedproductivity, leadingtosignificantfinancialloss.
Untilnow,shrimpbroodstockfedmatura-tion-formulateddiet,pelletedorextrudeddidnotmatchtheperformancesofanimalsfedonfresh/frozenfood(Woutersetal.,2002.Bragaetal.,2010).Formulateddiets tendtobreakdown due to the unique feeding behaviourof the animals, resulting in polluted waterandveryhighFCR.Moreover,palatabilityandingestionratesareusuallylow.Evenusingthesame foodorganismsasdrymeals in formu-

Recently, a new maturation diet(NutraFeed®) for crustaceans that cancompletely replace the use of fresh/frozenfeed was developed. The diet is semi-moist(around 30-35% moist) and manufacturedas short pellets at any length and diameterneeded. The diet is stable in the water for24hoursandwillnotbreakdownwhentheshrimpisholdingandchewingit.
NutraFeed®dietsarebasedsolelyondrymeals without any fresh or frozen products.Theyarecertifiedaspathogenfree(allingre-dientspassGammaradiation)withashelflifeof six months (refrigerated) or 12 months(frozen).Toboostthehormonalcycle,herbalextracts (NutraGreen® products) are incor-poratedintothediets.Theseare100percentnatural additives aimed at improving brood-stock performance including; enhancing eggandlarvaequality,spermmortality,vitellogen-esis, aswell as immunesystemanddigestivesystemsupport.
Large experiment To compare the performances of the
maturationdietagainsttraditionalfresh/frozenfoodorganism, a large experimentwas con-ducted independently by one of the biggestshrimp producers in the world. The results(seeTable1)showedsignificantperformanceimprovements when the broodstock fed onNutraFeed®semi-moistdiet.
Moreover, using the semi-moist diet alsoproved to be cost effective compared totraditional diets. Two hundred white shrimpL. vannamei were fed control diet (squid,polychates and nutritional booster) orNutraFeed® SM diet. The broodstock werekept in identical tanks and under the sameenvironmental conditions. Growth, mortali-ties,spawningevents,fecundity,hatchingratesandnumberofnaupliiweredeterminedover124days.
The diet was also used with domesti-cated P. monodon broodstock in Australiawith remarkable results.

What is your role at Offshore Mariculture?
As Chairman, I hope to stimu-latediscussion.ButIamalsoverymuchtheretolistenandlearn,aswell.Iwillaskthedumbquestions,to save others from the embar-rassment.
Who is Offshore Mariculture aimed at?
Industry – those who aspireto grow their aquaculture oper-ations, and to expand fur theroffshore, into deeperwater.Andisn’tthatallofus?
What are the themes of Offshore Mariculture?
The expansion offshore isstar ting now. More correctly, ithas started.We have the capa-bility,wehavethe incentives,andwe have shown we can do thisinanenvironmentallyresponsibleway.
The technology that allowsoffshore farming is now refinedtoanewlevelofoperationaleffi-ciency in Kona, Panama, Chile,Canada, Norway … farms inmoreandmoreexposedsitesareabletooperatewithgreatereffi-cientlyandprofitably.
There is also exciting researchout ofAustralia and Kona thatsuggests that offshore culturesystems may actual ly offerimprovedbiologicalperformanceofthefish,withfasterfishgrowth,higher survival, better FCRs andlowerstress.
And the environmental datais overwhelmingly positive.Withover a decade of operation inthe offshore environment, there
is now a resounding body ofevidence of no significant envi-ronmental impact – usually nomeasureable signature fromoperations at all. Attheconference,FAOisgoing to be reportingon a soon-to-be-pub-lished study from agroup of experts thathavecollatedtheglobaloffshore culture expe-riences to date, con-sideredalltheavailabledata, and reached thissameconclusion.
What can participants expect to see and do?
Theycangetupdateson s igni ficant newadvances in numeroust e chno logy a rea s :mooring systems fordeepwater,newnettingmaterials,new submersible pen systems,andnewfeedsdevelopmentthatreduces the reliance on foragefisheries.
With so many industry shows, why should people attend Offshore Mariculture?
It focuses exclusively on thechallenges and opportunities ofoffshoreculture.
What are you most excited about for Offshore Mariculture?
What was once aspirational isnow demonstrably achievable.Theconferenceoffersanoppor-tunity to clarify the commercialopportunities for expansion intothetrulyoffshorerealmoverthenext decade – to separate theclever research from the com-merciallyrewarding.
What are you going to make sure you see/do at Offshore Mariculture?
I am keen to see more of the
Norwegian developments inoffshoretechnology.
Iamalsoeagertoseethelevelofoperational efficiency that the
Turkish aquaculture industry hasbeenabletoachieveonexposedfarm sites. How far offshore,how deep, and what sea condi-tions?
How does this event compare to previous ones?
There is growing recognitionfrom NGOs and internationaldevelopment agencies that themuch-vaunted‘Blue Revolution’has to happen.We must makeithappen! It is theonlywaythatwe can feedninebillion increas-ingly affluent, health-consciousconsumerswiththeseafoodthatthey crave and need, withoutfurther impacting already heavilyexploitedwildstocks.
And there is growing recogni-tion that the offshore pioneersare making this vision becomingreality.And that reality is hap-peningrightnow!
Any other news or things you would like to discuss?

TheUShasdemonstratedoverthe last 10 years how not todevelop an offshore aquacultureindustry.The responsible, sustain-ablegrowthofaquacultureintherest of the ocean realm shouldnot be hobbled by similar inef-fectuality.
