FISHERY, BIOLOGICAL STATUS AND STOCKS OF THE KORFO-KARAGINSK HERRING IN THE RECENT PERIOD
The results of the analysis of fishery, biological state and estimates of the of korfo-karaginsk herring stock in 2011-2021 are presented. It is shown that after the lifting of the ban on the specialized herring fishery in 2011 and the increase in the catch, its volume gradually decreased and then stabilized at the average level of 43 thousand tons. The main catch is in November-December, and it is mainly carried out with midwater trawls. The basis of commercial catches in 2011-2013 consisted of fish of the 2007-2009 generations of age 4+. Then a long predominance of older age groups was observed. The main spawning area was Anapka Bay, that is typical for this population at the average level of its abundance. The results of avia and egg surveys showed a trend towards a decrease in the spawning stock. According to model estimates, both spawning and total stocks also declined in the period under consideration after the 2017 biomass peak. It is assumed that the catch in the coming years will remain at the same level and amount to 40-50 thousand tons.
