Despite the abundance of information accumulated over the years of fishing and research, the uncertainty of the dynamics of the stock remains quite high. The article describes and analyzes all currently known sources of information about the state of the stock –data from surveys, fishing statistics and the age structure of catches. Several types of models are being built – production models and age-structured model. The MSY value at the level of 28–32 thousand tons were obtained as a result of applying three different approaches to stock modeling: production models, combining cohort and production models and constructing a yield-recruit curve based on cohort models data. Despite the much greater uncertainty in the estimates of biomass, the current fishing intensity can be considered close to optimal based on the estimates obtained.","PeriodicalId":129863,"journal":{"name":"Problems of fisheries","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130257667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since 1950, a sharp increase in water temperature has been observed, and thermal regime shifts occurred in 1977 and 2014. Composition and structure of zooplankton communities are virtually the same as in the western Bering Sea basin. Zooplankton community is comprised by a small number of widely distributed species, which belong to macrozooplankton and constitute a valuable food source for upper trophic levels. Nekton biomass is small, an order of magnitude lower than on the shelf. Neighboring continental slope and underwater ridges, as well as seasonal migrations of lower boreal and lower boreal-subtropical species support high species richness of nekton community. Pelagic and benthopelagic species of fish and squid, which occur on the shelf and slope, usually do not migrate into the Convention area in large quantities, except for walleye pollock, which was actively harvested in this area in 1983–1992. However, in the up-coming years, it is impossible to resume pollock fishery in the Convention area, based on the modern state of pollock resources.","PeriodicalId":129863,"journal":{"name":"Problems of fisheries","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121638922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over the past 5 years, they have been in the range of 2245–2808 tons. The closure of industrial fishing in 2007 led not to an increase, but to a decrease in fish stocks, due to a decrease in the rate of their linear and weight growth, deterioration of exterior and commercial qualities. The material damage caused by the closure of industrial fishing at the Ivankovsky reservoir since 2007 has been determined. To determine the material damage caused by the closure of industrial fishing at the Ivankovsky reservoir, retail prices for 21 types of fish were determined. The resulting value for each type of fish was correlated with the volume of fish that was not caught due to the absence of fishing in the period from July 2007 to 2022. Data on catch volumes in the Ivankovo reservoir are taken from the Orders on approval of the total allowable catches and recommended catch of aquatic biological resources in 2007–2022.
