Introduction to Fisheries and Aquaculture Technologies
22. Development & Management of Fisheries Resources in Floodplain
01. Contact division/person/unit BFRI Sub-station, Santaher, Bogra.
02. Location of appl ication Beels, Haors, Baors etc.
03. Key characteristics of a. Determination of suitable stocking density of carps in
technology floodplain.
b. Identification of productive area.
c. Control of fishing gear.
d. Enhancement of fish production.
04. Management guidelines a. The biological life cycles of three beels to be
determined on the basis of various informations. The
stocking density, species selection and ratio of fish in
each beel is also recommended.
b. Fishing nets and gears used in the beels have been
identified and also to determine the harmful affect of
those gears in fish life cycle and also recommendations
have been made to use those gears in particular water
bodies.
c. Comprehensive informations have been made available
on natural food availability on the basis of physico-
chemical properties of water in beels. This information
can be used for assessment of comparative productivity
features of different floodplain ecosystem in
Bangladesh.
05. Impact of environment Improvement of natural habitat of floodplain will allow
to increase fish production.
06. Procedure of transfer The management guideline can be used by the
Government and non-government agencies.
07. Expected outcome Fish production in beel floodplain ecosystem will be
increased.
08. Recommendations The fish production as well as socio-economic status of
fishermen will be improved through proper stocking
management offish in beels.
23. Environment Friendly Coastal Aquafarming of Shrimp and Finfishes on Crop-rotation
Basis
01. Contact division/person/unit Marine Fisheries and Technology Station, BFRI, Cox's
Bazar.
02. Location of application Coastal areas of Bangladesh.
03. Key characteristics of the a. No successive two crop of shrimps or finfishes in the
technology same pond.
b. Alternate crops of shrimps during dry season and
finfishes during wet season if two crop are practiced.
c. If a single crop is raised annually shrimp in a year
would be followed by fish during next year.
