Since 2008, due to the change in the fishery research financing system,
a decrease in research variety was noticed. After changes in fisheries
legislation, the use of the "quasi-budget" financing through the implementation
of "scientific" quotas was discontinued. Obvious enough, that the destruction
of valuable living resources caught during research fishing led to inability of
fisheries research to ensure innovative development of the branch, as well as
to preserve the scope of research achieved by 2008. Despite this, the studies
carried out in 1994-2014 have significantly expanded the understanding
of the Atlantic salmon biology in the Northern Dvina River. The observations
produced extensive material on migration dynamics, catch on effort in fishing
gear, length and weight indicators, sex and age structure of spawning herds
of Atlantic salmon of the Northern Dvina River.
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.
