Establishment of norms for the output of granular salmon caviar from the chum salmon of the Okhotsk region with a machine method of punching

The efficiency of Pacific salmon fishing is largely determined by the quantity and quality of the products produced. Chum salmon (Oncorhynchus keta) is the second most commercially important species among Pacific salmon. In order to determine the norms of waste, losses, output of finished products and consumption of raw materials in the production of granular salmon caviar from the chum salmon of the Okhotsk catch area of the North Okhotsk subzone, pilot control work was carried out within the boundaries of the Khabarovsk Territory. As a result, the average values of waste, losses, consumption of raw materials and output of finished products in the production of granular chum salmon caviar on an egg–punching machine with an installation for washing caviar-grain were established. The yield of granular chum salmon caviar was 80.1%, the consumption coefficient of raw eggs per unit of finished product was 1.248.
