Magadan branch of VNIRO completed scientific support of Gizhiginsko-Kamchatka herring fishery in the Sea of ​​Okhotsk

 

During the entire period of the herring fishery, an observer from the Magadan branch of the State Research Center of the Russian Federation "All-Russian Research Institute of Fisheries and Oceanography" (VNIRO), the head of the group of commercial marine fish - Filipp Burlak carried out daily observations of the fishing situation, the composition of herring catches and by-catch objects, collecting materials on the size-age, weight and sex characteristics of herring, the rate of its maturation and readiness for spawning, as well as data from trawl catches on other representatives of aquatic bioresources of the northern part of the Sea of ​​Okhotsk.

 

According to the preliminary analysis of the materials collected by the scientific observer, it can be stated that the general size, weight and sex characteristics of the structure of the commercial herring stock are relatively stable and correspond to the average values ​​of recent years.

 

Due to the sparseness of the ice fields in the throat of the Shelikhov Gulf, the herring schools were relatively unstable, which predetermined the need for an expanded search for its accumulations. This circumstance also affected the size of the average catch per vessel per day. In addition, a tendency was noted for an increase in the share of younger age individuals of the Gizhiginsko-Kamchatka herring in the catches.

 

The obtained materials will be used in preparing forecasts of the total permissible catch of the Gizhiginsko-Kamchatka herring population of the West Kamchatka subzone, and will also be in demand in the framework of developing recommendations for the rational exploitation of its stocks.
