Groundfish EFH Tasking for September Council Meeting

3

NWFSC/SWFSC Groundfish EFH Tasking for September Council Meeting

Specific tasks listed in briefing book, referenced by Council member

Prioritizing tasks based on available resources for completion by the Council's Sept. action (scoping)

For example:• Analyses of the effects of existing management measures

on groundfish EFH• Preliminary analyses of proposals (e.g., mapping and

cataloging impacts of proposals on fishing effort)

4

Theme 1: How do current EFH proposals relate to other factors?

• In relation to• Current trawling effort and availability• Catch• Each other• RCAs

• Conclusion: Straightforward GIS analysis, intended to be complete by September Council meeting.

5

Theme 2: What do we already know?

• What have been the effects of • Gear switches• RCA• Catch shares

• Conclusion: part 1• We will summarize existing studies addressing these

issues• Complete analysis is mult-dissertation worthy

• Conclusion: part 2• Preliminary analysis of Amend. 20 as part of BiOp

6

Theme 3: Do mid-water trawls really hit the bottom?

• Concern that the true effect of mid-water trawling on bottom habitats is not accurately characterized

• Conclusion: Tabulation of bottom-dwelling organisms (as proxy for hitting bottom) in hauls from catch data• For September Council meeting

7

Theme 4: Did you guys use those EFH boundaries anyway?

• Issues• Any mistakes?• Did EFH factor into decision-making?

• Conclusion:• List of wrongly/poorly placed boundaries (e.g. Potato

Bank)• Table of decisions/etc. using EFH• Policy side to deal with these

Center for Independent Experts (CIE) Panel Review of the

Joint Pacific Sardine and Hake (SaKe) acoustic-‐trawl surveys

January 21-24, 2014Seattle WA

CIE Review of the Joint Hake-Sardine survey Terms of Reference:1. Evaluate the historic, independent sardine and hake surveys 2. Evaluate the current joint SaKe survey 3. Evaluate the tradeoffs of transitioning from independent surveys

to a joint sardine-hake survey.4. Evaluate the potential of the SaKe survey to provide status and

trend info for hake and CPS5. Evaluate the costs and benefits of :

• Separate and joint hake and sardine surveys • Biennial v. Annual• Ecosystem v. no ecosystem information.

• Provide recommendations to increase the efficacies and efficiencies (e.g., through advanced technologies) the survey

NWFSCSWFSC

• Conclusion 1: Joint survey is strongly supported

• Hake and CPS assessment support• Basis for ecosystem studies• Climate response

• Response: All right, then• Centers continue to develop and implement

joint efforts

NWFSCSWFSC

• Conclusion 2: A development phase is needed before “annual production”

• 5 years• Techniques/methodologies• Resource development

• Response: yes!• 2014 – survey and development year

• Net testing – interchangeability• Acoustic development

• Integrate experiments with surveys

NWFSCSWFSC

• Conclusion 3: Improve coordination• Between Centers• With Canada and Mexico

• Response: Long-term and ongoing efforts• Working group for planning and design• Better coordination on data storage and

processing• Work to expand international (i.e. biologically-

appropriate) coverage

NWFSCSWFSC

• Conclusion 4: Research Areas• Transect spacing, direction of survey,

simultaneous use of 2 vessels• Development and validation of geostatistical

techniques• Migration behavior and rates• Target strengths and species id

• Response: Prioritizing and Pursuing• Multiple review efforts (SRG, Program Review,

CIE)

NWFSCSWFSC

• General Issues Raised• Possibly oversampling (transect density)• Length of time of survey• Understanding ecosystem dynamics is as

important as biomass estimates• Juvenile indices• 2nd vessel (Lasker) to provide additional

opportunities• Climate change

NWFSCSWFSC

• A joint survey with oceanographic sampling provides “a grand opportunity to work towards a true ecosystem-based survey that provides advice for stock assessment of the main commercial species plus the ecosystem information needed to fully understand productivity changes… that are currently occurring or coming at us soon.”

2014 Summer SaKe Survey and beyond

SWFSC

• Survey Dates June 24-September 14, 2014

• First two legs are a Synoptic Acoustic-Trawl survey of CPS in the California Current Ecosystem

• Last two legs are hake specific research investigating survey methods, life history, and associated ecosystem

Moving Forward / Moving Parts

SWFSC

• This year• Survey + research• Planning meeting aimed at addressing issues

• Moving Parts• Results of methodological tests• Ship time• Other resources• Standardization of data• Interoperability of data and equipment

New FSV to addressCalifornia Current ecosystem questions The Lasker is the fifth in a series of

Oscar Dyson-class ships (208 ft; 63m) home ported in San DiegoEquipped with technologies for fisheries and oceanographic research, including advanced navigation systems, acoustic sensors.

• Five-frequency split-beam echosounders

• Scanning, Multi-beam and Imaging Sonars

The ship is engineered to produce less noise than other survey vessels.
