A generalized linear model (GLM) was used to assess the factors affecting the red king crab fishery efficiency in the Russian EEZ in the Barents Sea in 2010-2018. It was found that the efficiency dynamics mostly depend on production factors (type of trap and vessel), rather than environmental factors (depth, temperature, salinity, bottom type, distance from the coast). Stepby-step inclusion of factors in the standardization model has shown that the annual fishery efficiency dynamics in addition

... to the year effect (40% of the explained variance) are mostly influenced by the following factors: vessel, trap type, number of traps in order, month (or week). It is possible that the temperature factor significance will be increased with an increase in the fishing season, whereas now, subject to the short fishing seasons in 2014-2018, its contribution is insignificant.
