Updating the rates of output of pollock processing products based on statistical analysis of experimental data. Message 2. Updating the rates of walleye pollock processing products in the West Bering Sea, East Kamchatka, North and South Kuril zones

Abstract

The purpose of this study is update the norms for the output of walleye pollock processing products for the Far Eastern fishery basin based on a statistical assessment of the results of experimental control works aimed at improving the fishing regulation system in terms of verifying actual catches. Methods used: experimental and control work was carried out according to the «Methods for determining the consumption rates of raw materials in the production of products from hydrobionts». 145 experimental and control works were carried out, the mass of raw fish directed to their implementation was 21499.4 kg. Calculations of the results of experimental and control work using the «Complex of programs for processing the results of experimental control works in the production of frozen products from raw fish (except for sturgeon and salmon)». Novelty: it has been established that the use of modernized fish cutting equipment or new generation machines can increase the yield of headless walleye pollock by 3,8 %, and output skinless and boneless walleye pollock fillets in season «B» increased by 2,9 %. For the first time, the output of skinless, boneless fillets from walleye pollock in season «A» was established, which amounted to 26,9 %. Result: this article is a continuation of the great work carried out by the Federal State Budgetary Scientific Institution «VNIRO» to update the rates of output from walleye pollock. In the first message, the rates of output from the Sea of Okhotsk pollock were considered, in the second message the data on the output of production from the West Bering Sea, East Kamchatka, North and South Kuril zones. Practical significance: the developed rates for the yield of walleye pollock processed products in 2020 included in new collection of «Basin rates for waste, losses, finished product yield and raw material consumption in the production of frozen and fodder products from fish of the Far East region».
