The Potency Of Curing Fish Waste Pellet For Growth And Protein Level Of African Sharptooth Catfish (Clarias gariepinus)

摘要

Fish curing in Kenjeran, Surabaya produces waste such as fish offal, tail and fins which still has some nutrients, especially protein content, so it can be used as fish feed. Fish feed is an important factor in fish growth. Farmers usually use commercial fish pellets, but the price is relatively more expensive. Curing fish waste which is less expensive can be used as materials for pellets. The purpose of this study is to utilize curing fish waste as a material fish pellets for growth African catfish. Experimental design of this research is Completely Randomized Design (CRD) with 1 factorial. The pellets varieties were of K.O, K.l, K.2, K.3, and K.4. The pellets were given to the fish for 30 days. Data of growth rate, survival rate and FCR and protein level data of the pellet and the fish flesh were analyzed by one-way ANOVA statistical method. The analysis shows that the K.4 treatment has a best result of relatively growth of length (72.64%)and relatively growth of weight (488,97%). Protein level of fish flesh is 20.97%. The survival rate of 98%, FCR most efficient pellets exist is K.4.
