Inclusion of Monosex Tilapia (Oreochromis niloticus) with Freshwater Prawn (Macrobrachium rosenbergii) in Polyculture Systems in the Ponds of Coastal Region: Impact of Stocking Density of Tilapia on Production and Profitability

Giant Freshwater Prawn is one of the freshwater commodity which have an economy value where Nilem carp has also potentially to be cultured to produce fingerling size as a “baby fish”. The purpose of this experiment is to determine the optimal survival, growth, FCR, and productivity of Giant Freshwater Prawn and Nilem carp cultured on polyculture system and also biomass productivity of bio filter (snail, water spinach, and Cabomba). The different stocking density of Nilem carp as a treatments were as followed: A) 25 fish m-3 B) 50 fish m-3, and C) 75 fish m-3. Density of Giant Freshwater Prawn was 20 individuals m-3 for all treatments. The result showed that the optimal of survival, growth (length and weight), productivity and FCR for Giant Freshwater Prawn was found at density of 25 fish m-3 (A) than that of density 50 fish m-3 (B) and 75 fish m-3 (C) (P<0.05). The highest of biomass productivity of bio filter (snail, water spinach, and Cabomba) was found at density of 25 fish m-3 (A) than that of density of 50 fish m-3 (B) and 75 fish m-3 (P<0.05). Water quality such as DO, temperature and pH showed almost the same at all treatments.

Education Levels

The study was carried out to know the present status of Macrobrachium rosenbergii culture in Bagerhat district, Bangladesh from March 2012 to January 2013. Education levels of farmers were found as illiterate (12.3%), primary (36.19%), secondary (20%), SSC (13.33%), HSC (12.38%) and graduate (5.71%). M. rosenbergii culture was the primary and secondary occupation of 80% and 20% farmers respectively. Average stocking density and production in extensive, improved extensive and semi-intensive culture were 9609, 11502 and 22847 per ha and 193, 284 and 488 kg/ha/year respectively; rearing period ranges from 6-10 months and survival rate varied from 55 to 60%. In improved extensive and semi-intensive culture 82.86% and 71.43% farmers applied farm-made feed instead of company feeds respectively and 11.43% and 37.14% farmers used both feeds. 91.43%, 80% and 68.57% respondents responded on normal to high mortality in extensive, improved extensive and semi-intensive culture respectively. Lack of finance and appropriate technology, scarcity of quality PL, diseases and inadequate extension work were major problems of prawn culture.
