Researchers find uses for fish waste

The Fishery Industrial Technology Center (FITC) Agricultural Research Service seafood processing byproducts project has resulted in a number of ways to use fish waste products, and is studying even more uses. The project, which has been going on for 11 years, was started with one goal: finding out how to convert fish processing waste into aquaculture feed ingredients.

“This was the area where there was the greatest utility for the products that we could easily make,” FITC professor Scott Smiley said. Fish processing byproducts or waste are the parts left over after food portions are removed. The major waste components are heads, frames (what’s left of the body when fillets are cut off), viscera (guts including testes, ovaries and livers) and skins.

Smiley said Alaska harvested 2,090,379 tons of fish in 2008. Much of that results in waste. For example, about 35 percent of fish weight for landed salmon that is canned becomes waste. Only 65 percent goes into the can. Pollock surimi results in 80 percent of the product becoming waste. Read more ...
