The contribution of this water area to the total catch of rockfishes in the Petropavlovsk-Commander subzone in 2001–2022 did not exceed 26.5%. Near the Commander Islands, S. alutus was observed at depths of 138–370 m at a water temperature near-bottom of 3.1–3.9°C, and in catches it was represented by individuals 17–45 cm length. Presumably the formation of accumulations in the upper part of the continental slope to the west of the Bering Island is due to the presence of an anticyclonic circulation, which contributes to the formation of high concentrations of zooplankton as the main food source and favorable conditions for the development of spawned larvae.","PeriodicalId":508003,"journal":{"name":"The researches of the aquatic biological resources of Kamchatka and the North-West Part of the Pacific Ocean","volume":"41 24","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140259288","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}
