Long-term dynamics of biomass and modern fishery of atka mackerel Pleurogrammus monopterygius in the Pacific waters of Kamchatka and Kuril Islands
Dynamics of commercial stock for the Kuril-Kamchatka population of atka mackerel is evaluated on the data on size-age structure of its catches and fishery statistics for 1968-2014. Long period of low abundance was observed until the early 1990s, with the minimum stock in 1976-1977 when the spawning...
