Introduction to Fisheries and Aquaculture Technologies
16. Fish Feed Development from Indigenous Ingredients and their Method of
Application
01. Contact division/person/unit Freshwater Station, Bangladesh Fisheries Research
Institute, Mymensingh.
02. Location of application Nursery ponds and perennial rearing ponds in all over
the country.
03. Key characteristics of the a. Formulation of feeds based on nutritional requirements
technology offish using locally available cheap raw materials.
b. Culture of fish with higher stocking densities.
c. Higher growth and survival rate.
d. Effective feed conversion ratio.
04. Production guidelines a. Carp Nursery feed: Fish meal 21%, rice bran 28%,
mustard oilcake 42%, ata 8%, Vit. + mineral 1%.
b. Cost of Feed: Tk. 13.00-14.00/kg.
c. Polyculture feed : Fish meal 10%, rice bran 50%,
mustard oilcake 31.5%, ata 2%, Vit. + mineral 0.5%,
molasses 5%.
Method of application Nursery feed: @ 10-20% of body weight of the fish
2-4 times daily.
Polyculture feed: @ 2-5% body weight of fish once
or twice daily.
Production With nursery feed : @ 400,000-600,000
fingerlings/ha produced within 3 months; FCR 1.5 : 1
With polyculture feed : @ 6-7 tons of fish/ha/yr.
AFCR2: 1
Cost involvement and benefit Nursery feed:
Total cost: Tk.1,35,715
Total income : Tk. 3,36,000
Net profit : Tk. 2,00,285
Polyculture feed:
Total cost : Tk. 1,26,515
Total income : Tk. 2,70,000
Net profit : Tk. 1,43,485
05. Risk involvement and a. Protection against loss of nutritive value due to
management in adopting the improper storage.
technology b. Care against wastage of feed due to over feeding or
improper application.
06. Impact of environment a. No adverse effect on enviro-nment.
b. Use of excess feed than the recommended dose may
deteriorate water quality.
07. Procedure of transfer Through DoF and NGOs.
08. Expected outcome a. Increase fish production 5-7 times more than the
present rate of production.
b. Improvement of socio-economic condition of farmers.
c. Better utilization of closed water bodies.
09. Recommendations a. Quality feed ingredients should be ensured.
b. Use of feed in excess needs to be avoided.
