Improved productivity and efficiency of the culture based fishery for giant freshwater prawn in Sri Lankan reservoirs. (Old ID 26163)
Role
Principal Investigator
Description
Productivity of the fisheries resources of Sri Lankan reservoirs has been improved through application of culture based fishery (CFB) practices. In addition to a variety of finfish that serve to provide protein to local communities, the addition of stocked giant freshwater prawn (GFP)-Macrobrachium rosenbergii, has added significant value, due to high market price, 10 times higher than that of finfish. Currently, the GFP are captured as a bycatch to finfish and the stocking practices are ad-hoc, resulting in very low yield per seed prawn stocked. The fishery is managed as a single multi-species fishery, and although the project will focus on research of GFP, some aspects of the research will involve the entire fishery, particularly modelling of stocking and yields. This will provide benefits for production of all species, with an emphasis on enhancement of GFP production through specific research of stocking practices, production dynamics, harvest and socio-economic aspects 0of the fishery and the supply chain.
