COMPLIANCE WITH ETHICAL STANDARDS

: The authors declare that they have no conflict of interest. This article does not contain any studies involving animals or human participants performed by any of the authors. The material for assessing qualitative characteristics of Pacific salmon spawners was collected from commercial catches of fishing companies.The authors of the study are representatives of the sectoral institutes of the Federal Agency for Fishery (Rosrybolovstvo), which is the state regulator in fisheries aimed at conservation of aquatic biological resources and ensuring their rational use. Any lobbying for the interests of fishing companies through increased fishing pressures on populations would impede the objectives of providing the optimum escapement of spawners to their spawning grounds and contradict to the objectives of sustainable fisheries. As a result of the study, a tool for prompt regulation of fishing is proposed to be used by the regional Commission for Regulation of Harvesting (Catch) of Anadromous Fish Species, which allows collection of objective information about the current escapement of spawners to spawning water bodies in real-time mode for making competent management decisions.

: E.S. Fadeev organized and implemented field studies in the Lake Azabachye basin, at the fish-counting cross-section of the Kamchatka River (FS no. 832), including the period preceding the fishing season, was an operator of two hydroacoustic systems and an unmanned aerial vehicle, and wrote the first version of the article. E.A. Shevlyakov designed the concept of research, took part in the planning and organization of works, and critically revised and edited the article. M.G. Feldman performed mathematical processing of the collected materials, developed an algorithm for assessing spawners’ escapement through a cross-section of the river based on data of catches. All the authors participated in the analysis, interpretation, and discussion of the results.
