Modified silage process for fish and fish processing waste

Dried fish silage was made from fresh and frozen whole fish, and fresh and frozen viscera and processing waste. The Modified Silage Process (MSP) uses less acid and lower temperature than common fish silage processes and recovers over 90% of the fish solids and oil in a stable dry meal. Feeds made from different fish and processing wastes using the MSP performed as well as a commercial feed. Feed conversion ratios (FCR) for MSP feeds were 0.86 with juvenile salmon. An economic evaluation of the MSP using the Net Present Value model illustrates where the MSP may contribute to the processing of fishery byproducts in Alaska or other remote and seasonal situations.
