Type: dissertation
Abstract: In India a study conducted by CIFE and CIBA (1997), concluded that\nshrimp farming does more good than harm and it is not eco-unfriendly\n(Krishnan and Birthal, 2002). Upsurge in coastal aquaculture activity\ninduced by high profitability is reported to have caused adverse impacts on\ncoastal ecosystems and social environments (Parthasarathy and Nirmala,\n2000). The crustacean farming sector has received criticism for excessive\nuse of formulated feed containing high protein, of which around 50% gets\naccumulated at the pond bottom as unconsumed (Avnimelech, 1999; Hari\net al., 2004, 2006). The wasted feeds undergo the process of degradation\nand results in the release of toxic metabolites to the culture system.\nReduction of protein in the feed, manipulation and utilisation of natural\nfood in the culture system are the remedy for the above problems. But\nbefore reducing the feed protein, it should be confirmed that the feed with\nreduced protein is not affecting the growth and health of the cultured\nanimal. In the present study, biofloc technology is identified as one of the\ninnovative technologies for ensuring the ecological and environmental\nSustainability and examines the compatibility of BFT for the sustainable\naquaculture of giant prawn, M. rosenbergii. This thesis starts with a general introduction (Chapter-1), a brief review of the most relevant literature (Chapter-2), results of various experiments (Chapter-3-6), summary (Chapter-7) and recommendations and future research perspectives in the field of biofloc based aquaculture (Chapter – 8). The major objectives of this thesis are, to improve the ecological and economical sustainability of prawn farming by the applicationof BFT and to improve the nutrient utilisation in aquaculture systems.
