Abstract—
The article presents analyses of the dynamics of injuries of the snow crab opilio in catches taken during surveys in 2008–2022, as well as data collected by observers in the fishery for this species in the Russian part of the Barents Sea in 2014–2022. The average proportion of injured crabs in catches taken during research surveys increased from 5–11% in 2008–2010 to 45% in 2022. The increase in the number of injured individuals in catches is higher for large males. The modeling results showed that the increased proportion of injured individuals in the period preceding commercial exploitation is associated with an increase in intrapopulation interactions, while during active commercial exploitation, it is associated with fishing pressure on the population, when some individuals, including crabs injured during capture, are returned to the sea after processing.
期刊介绍：
Oceanology, founded in 1961, is the leading journal in all areas of the marine sciences. It publishes original papers in all fields of theoretical and experimental research in physical, chemical, biological, geological, and technical oceanology. The journal also offers reviews and information about conferences, symposia, cruises, and other events of interest to the oceanographic community.
