How to feed fish with cassava peels to boost growth and productivity.
Fish is a valuable source of animal protein in human diets and also as protein in compounding of feed ration for animals. There is a need to increase production of fish for human consumption to meet the ever increasing demand by the population. There is a potential to produce locally that which is needed and even extend trade by exporting,but certain constraints are limiting growth. The cost of fish feed is a major constraint to productivity and farmers are always searching out ways to cut cost without affecting productivity. The fish farmers are very innovative when it comes to feeding the fish,they usually start with compounded feed(finished) to start them up after which they source out locally produced feed(home- made) and then they finish them off with compounded(finished) feed. In a bid to feed fish to boost productivity and growth several combinations have been used with success,read. Farmers have used cassava to feed fish in various combinations. Fish farmers often use a combination of cassava flakes with crayfish at mid-season and towards the harvesting time. Fish are fed with only cassava flakes also @1 week to harvest. The use of cassava peels have also been used to compound fish feed with tremendous success, learn how A study conducted to determine the growth response of fish to cassava peels shows that fish thrive very well on the peels using high inclusion rates. The study conducted at Department of Fisheries Technology, Federal Polytechnic Nekede, Owerri in 2012. The test used factorial design of five treatments of cassava peel meal at 0, 25, 50, 75 and 100% graded level . The cassava peel meal was sundried for 48 h, ground and added to the feed fed to 150 fingerlings of Oreochromis niloticus into 10 tanks in triplicates and fed twice daily at 5% body weight for 60 days. The result shows that fish fed with 100% cassava peel meal had the highest mean weight gain of 10.46±0.01 and specific growth rate of 1.23±0.04. The poorest result was shown by fish fed 25% cassava peel meal with the lowest survival rate, weight gain, feed intake and specific growth rate, respectively. more
