Seaweed is one of the underutilized types of raw materials in the Far East, the recommended annual catch of which is more than 150 thousand tons. Of the 500 species of flora of the Far Eastern seas, no more than a dozen are mined for the food industry. An important direction of the effective exploitation of macrophytes can be their use as feed and fertilizer in agriculture. An analysis of the possibilities for the widespread use of marine plants in agriculture determines the need for scientific research of marine plant materials according to a comprehensive program uniform for the entire Far Eastern basin.
Among the extraction of aquatic biological resources in the Far East and in Russia as a whole, Pacific salmon occupy the second place in the total catch of fish. A feature of the physiology of Pacific salmon is pronounced transformations during the period of putina, namely, changes in color, body shape, head, jaw curvature and tooth enlargement, different mass indicators of fish and the chemical composition of muscle tissue. In this regard, a differentiated approach is needed when developing standard-setting indicators for verifying Pacific salmon catches. The conducted studies allowed us to determine the norm-forming indicators in the production of frozen fish from pink salmon and chum salmon from different production areas, depending on their biological state.
The output of roe from pre-spawning Pollock was analyzed according to the standards set in the Law on Fisheries aimed at conservation and rational use of Pollock populations in the Western Bering Sea fishing zone, Karaginsky and Petropavlovsk-Commander subzones during fishing season in 2020. The output of Pollock roe (raw fish eggs) was evaluated at 10-days intervals, monthly and for the entire fishing season from January through February 2020 in the Western Bering Sea fishing zone, Karaginsky and Petropavlovsk-Commander subzones. It was concluded that the output of Pollock roe (raw fish eggs) calculated as a percentage of the total weight of raw fish, which were subjected to processing irrespective of sex (females and males treated together) during the 2020 fishing season, when legal specialized fishing for pollock was conducted in the Western Bering Sea fishing zone, Karaginsky and Petropavlovsk-Commander subzones, did not exceed the values determined in the Order №267 issued on 23 May 2019 by the Ministry of Agriculture of the Russian Federation.
Standardization, being an important element of the technical regulation system, acts as a tool for ensuring the safety and quality of food products, regulating safety indicators and basic technical requirements for the product. The analysis of the current interstate and national standards for canned shrimp, as well as the Codex Standard for canned shrimp CXS 37 - 1991 was carried out. Modern requirements for canned shrimp in terms of organoleptic, physical, chemical and safety indicators were determined. As a result, implementing the "regulatory guillotine" for documents that establish mandatory requirements for products, a single document on standardization for canned shrimp at the interstate level has been developed.
Application of enzymatic hydrolysis of macrophytes in the technology of feed for juvenile sea cucumber was justified. A basic recipe for compound feed based on fermented marine vegetable raw materials has been developed. Biological tests in the department for the reproduction of sea cucumber on the basis of the Pacific branch of the FSBSI VNIRO (TINRO) (Primorsky region, Popova island) confirmed the effectiveness of the use of fermented algae in the composition of feed. The average daily weight gains of sea cucumber individual increases, and the feed ratio decreases in comparison with feeds based on natural marine plants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
