CAGE FISH CULTURE
Bangladesh
This brief outlines the basic construction
method used in Bangladesh for fish cages. It
provides a step by step guide on how to make
them.
Cage culture is one of the best options for
women’s groups and non-resource base farmers
to cultivate fish using open water or common
pool resource (CPR) e.g. rivers and canals, for
consumption and income generation.
The River Erosion Project (REP) of Practical
Action-Bangladesh used cage culture
technology involving women in four sub-district
of Gaibandha where 1m3 floating cage were used.
A cage measuring 1 cubic meter, made of black polyethylene net, a bamboo frame, plastic floats, ropes - is
used to culture around 200-300 fish for a period of 4 to 6 months and able to produce 20 to 30 kg fish.
All cages have a top cover to prevent fish jumping and escaping and to avoid predation by birds.
