Utilisation of agricultural and fishery by-products in aquaculture in Kerala state, India
1999
Francis, George | Focken, Ulfert | Becker, Klaus
The south-western Indian state of Kerala is endowed with ideal conditions for fish culture. The inland water area of the state, comprising 242,000 ha of brackish water-bodies, 3,300 ha of fresh water tanks and ponds, 30,000 ha of reservoirs and 85,000 ha of rivers and rivulets, however accounted for only 34,000 tonnes of fish yield in 1990 which makes up about 2.34% of the total inland fisheries production in India as a whole. The situation is sought to be corrected. About 10,000 ha of inland waters are proposed to be brought under fish culture and fish production increased by 15,000 tonnes as an initial target. A burgeoning demand for nutritionally adequate fish feed could be foreseen at this juncture. One of the major challenges facing the feed industry is the need for developing feeding strategies based wherever possible upon the use of non food grade locally available feed resources. Unconventional materials, the use of which as fish feed do not conflict with human food security, have to be identified and their nutritional quality ascertained in order to cater to this demand. Fishery and agricultural by-products like prawn peeling waste, rice bran, coconut cake, groundnut cake, tapioca waste, tamarind and jack fruit seeds, which are readily available at minimal cost have been identified as potential fish feed constituents. Their chemical compostion was determined and the suitability of one of these (tapioca meal) for inclusion in tilapia feeds are tested.
