According to model calculations the total stock of saffron cod in 2020 amounted to 163,8 thousand tons.

In 2010-2020 the total catch of the saffron cod ranged from 4,3 to 14,5 thousand tons averaging 8,5 thousand tons. The most effective fishing by Danish seine is carried out in September and October with average catches of 9,1 and 11,5 tons per day respectively.","PeriodicalId":129863,"journal":{"name":"Problems of fisheries","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125859783","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}

It has been suggested that maturation every six months of only a part of females indicates the genetic predetermination of individual fish to the appearance of this feature. The breeding of domestic breeds of rainbow trout with bicyclic spawning will also greatly contribute to the realization of the biological potential of this species and open up new prospects for trout breeding in Russia.","PeriodicalId":129863,"journal":{"name":"Problems of fisheries","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130341430","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}

Such devices are promising for use due to their relatively low cost, ease of deployment and application. Experimental procedures were carried out from May 11 to June 9 in the Kruglaya and Tungusskaya bays (the northern part of the Okhotsk Sea) during the period of herring spawning. With the help of underwater robots, spawning grounds should be surveyed by short point diving and short transects. Series of screenshots of bottom, recorded on a mobile device, could be georeferenced automatically. The work should be accompanied by the recording of tracks, station coordinates and other attribute data in a mobile geographic information system (GIS). Unmanned flights over spawning grounds must be carried out in the mode of automatic linear and polygon missions or manually. For the orthophotos production, the optimal height is 150 m with a forward overlap of images no less than 80% and a side overlap no less than 50% (no less than 20% in case of very good bottom visibility and survey conditions). During harsh survey conditions, zigzag flights over spawning grounds at a height of 50 m are preferred with shooting a series of photographs without intersection and no orthophotos production. The materials of underwater and unmanned surveys, integrated into the desktop GIS, provide high accuracy and efficiency in estimating the area of spawning grounds, the maximum degree of documentation and verifiability of the obtained materials.","PeriodicalId":129863,"journal":{"name":"Problems of fisheries","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131748241","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}
