• Tilapia is a popular food fish that has been pond farmed for thousands of
years.
• Cage culturing makes it possible to grow tilapia in bodies of water where
draining and seining would be difficult or impossible.
• Examples of tilapia species and variants commonly grown in cages are
Nile tilapia (Oreochromis niloticus), Blue tilapia (Oreochromis aureus) and
the man-made variants Florida Red and Taiwan Red.
Introduction
Objectives
•To encourage the involvement of graduates in aquaculture sector.
•To increase the income of rural folks and reduce the migration to
urban area.
•To produce 6.5 metric tons of fish with the value of RM78,000.00
(USD23,000.00) per year.
Project Site
• Perak River, Perak, Malaysia.
•The longest river in Perak with
the length of 400km.
• It originates in the mountains
at the Perak-Kelantan -
Thailand border, and empties
into the Strait of Malacca.

Project Scope
• Small-scale freshwater cage culture of red tilapia in Perak River for 10 years.
• The proposed model for this small scale freshwater cage culture of red
tilapia consists of 4 floating cages with the dimension 3 × 4 meters and
depth of 1.5 meters.
• The fish will be harvested twice a year with the average weight of 800g
per fish.
Project rationality
Rationality:
• Tilapia can be cultured at high densities in mesh cages that maintain free circulation of water.
•The breeding cycle of tilapia is disrupted in cages, and therefore mixed-sex populations can be reared in cages.
•Flexibility of management
•Ease and low cost of harvesting
•Close observation of fish feeding response and health
•Ease and economical treatment of parasites and diseases
•Relatively low capital investment compared to ponds and raceways.
Methodology
Project Description:
Frame Galvanized steel and wooden planks
Netting Nylon (mesh size 0.75 – 1 inch)
Floats Empty barrel
Mooring Cement anchorage and tied to nearby trees or poles
Methodology (Cont.)
Water Quality:
Temperature (oC) 28 – 30oC
Dissolved Oxygen 5 – 7 ppm
pH 7 – 7.5
Free ammonia 0 – 0.5 ppm
Nitrite Less than 0.3 mg/l
Nitrate Less than 300 ppm
CO2 Less than 20 mg/l
Water Current 10 – 20 cm/sec
Minimum water depth 2 meter
Methodology (Cont.)
Stocking:
• Tilapia fingerlings of 4-inch average
size will be obtained from a nearby
private hatchery
•Each cage will be stocked with 1200
tilapia fingerlings
•Fingerlings will be acclimatized on the
site especially for temperature
Methodology (Cont.)
Feeding:
• Commercial pellets
• Feeding adjustment – daily, weekly / biweekly
(flexible; based on feeding activity)
• Fish sampling will be utilized in feed
adjustment
Fish Size (g) Feeding rate (% Biomass/Day)
<10 9-7
10-40 8-6
40-100 7-5
>100 5-3

Methodology (Cont.)
Sampling and harvesting:
• Sampling will take place monthly
• It will be sufficient to randomly sample about 50 specimens/cage. Fish will be
collectively weighed and counted to get the average weight
• An adequate number about 20-30 fish per cage will be individually weighed
and measured to obtain the condition factor.
• A week before the tentative date of harvest, a pre-harvest sampling will take
place to determine the harvest time and/or actions which could be needed
• To remove fish during sampling or harvesting, the cage is partially lifted out of
the water and fish are captured with a dip net.
• Depending on size variation, the harvest could be selective (harvest the
target size and keep smaller fish for further growth) or could be a complete
harvest.
• Therefore, four weeks or more maybe required for complete the harvest
Finance and Labor
Financial Source:
Soft loan of RM30,000.00 (≈USD 10,000.00) are given to young
“agropreneur” – youth between the age of 18 until 35 to start agriculture
projects by Agrobank Malaysia with a grace period of 1 year. If the
project is successful, the young agropreneur can increase the soft loan to
a maximum of RM300,000.00 (≈ USD 100,000.00).
Labor:
As this is a small scale aquaculture with 4 cages, minimum labor is
required and only involve family members.
