Commercial Fish Meal
Protein Hydrolysates
Protein Hydrolysate Processing
п‚— Hydrolysate technology can offer smaller
processors a cost effective method to handle their
seafood processing byproducts.
п‚— Possible to produce high quality oils and protein
feed and fertilizer products
Protein Hydrolysis - Enzymatic Process
Experimental Hydrolysate
Production in Kodiak

Oil from Aquaculture Raised Catfish
п‚— Catfish oil can be extracted for viscera and used as
food and feed ingredients
п‚— Oleic and linoleic acids accounted for ~ 86% of
unsaturated fatty acids (different from marine oils)
Fish Bone
Fish bone is combination of
minerals and protein
Mineral supplements and premixes
Fish Bone Meal Products
Dried Fish Bone Snacks
Can We Add Value to Parts, Pieces,
and Organs ?
