Prospects for the Disposal of By-Products from the Processing of Aquatic Biological Resources

The expediency of using waste generated during industrial processing of commercial aquatic biological resources is justified. By-products obtained as a result of cutting fish and non-fish objects represent a significant source of biologically valuable substances. The article provides information on the use of secondary raw materials for the production of feed products for farm animals, birds and aquaculture facilities for the production of biologically valuable products, biofuels. The paper presents an assessment of the technological potential of by-products formed during the processing of the most profitable commercial objects – crabs and salmon. Such bu-products include carapace of the cephalothorax, crab entrails, as well as the caviar film remaining during the punching of salmon fish hawks. The assessment of the total chemical composition of the waste from the cutting of the blue crab was carried out. The high biological value of the hepatopancreas and carapace crab proteins was revealed. The general chemical waste from punching of chum salmon hawks is given. The high biological value of these waste lipids was confirmed by evaluating their fatty acid composition. The possibility and necessity of using the studied waste for the production of biologically valuable products is experimentally justified.
