Research Project: ALASKA FISH PROCESSING BYPRODUCTS Project Number: 5341-31410-004-00
Project Type: Appropriated

Start Date: Nov 03, 2009
End Date: Jan 12, 2012

Objective:
The over-arching goal of this project is to develop new knowledge to increase the value of underutilized seafood processing byproducts as food and feed ingredients in a sustainable manner. This will be achieved by accomplishing the three listed objectives. 1. Develop new and improved feed ingredients and high value human food products using fish processing co-products. 2. Develop economical processes and methods for the collection, stabilization and storage of raw seafood byproducts to optimize their chemical, nutritional, and physical qualities for uses including food and feed ingredients, fertilizers and bio-chemicals. 3. Develop ingredients from fish processing co-products that meet larval and stage specific physiological requirements of marine fish when used in modern dietary formulations.

Approach:
Fractions prepared from pollock and salmon byproducts such as fish meals, hydrolysates and stick water will be identified that promote growth in targeted aquaculture species fed plant protein based diets. Also, aquaculture ingredients from fish byproducts such as enriched fatty acid and phospholipid fractions will be identified that increase performance in targeted species. A continuous system for purifying and stabilizing salmon and pollock oils extracted from byproducts will be developed that can be used in smaller rural processing plants. Machine vision systems will be developed that can identify individual byproduct components such as liver and then efficiently separate the parts for further processing or packaging. Processes will be developed that improve the functional properties of fish skin gelatin films and other gelatin products in collaboration with scientists at WRRC in Albany, CA. Constituents of testes and other meals that positively affect shrimp and fish growth will be identified for use as aquaculture ingredients. The minimum levels of dietary omega 3 fatty acids required to sustain good growth and health of trout at different life stages will be determined. Economic analyses of the cost effectiveness of different methods of handling seafood processing byproducts will be provided to stakeholders. Collaborative studies between ARS and University of Alaska scientists will be conducted in the pilot plant and laboratories in Kodiak and Fairbanks, AK, and feeding trials will be conducted at the University of Idaho and the Oceanic Institute in Hawaii.
