Utilization of enzyme hydrolysis from Shrimp Head in improve the quality catfish

Protein is one of the most important components that can support growth and development catfish. The price feed with high protein content which relatively expensive a big problem in catfish farming process. On hand, there shrimp head waste source 42.16% - 49.8% has not been utilized disposed as waste. Through this research, was carried out by an enzyme hydrolysis process to produce soluble extract (SSE) using protease enzyme. SSE produced then given aged 14 days addition sources for During 1 month trial, significant difference results treatment 2% compared control gave very good effect on weight randomly distributed tank containing 50 average initial 0.6-0.8 grams. provision simultaneously standard fish feed, namely 3 times day. increase after being treated about 2 grams/week. This indicates be used alternative supplement future because reducing level pollution due waste, it also new discovery field fisheries.
