This article aims to analyze Russia’s efforts, both domestically and internationally, to combat illicit crab harvesting and safeguard its marine resources. A comparison of total crab imports and allowable catch in Russian waters from 1990 to 2022 indicates a peak in shadow activities during the mid-2000s, with a cessation of large-scale illegal fishing observed since 2013. A narrative analysis of institutional shifts reveals that the bolstering of internal oversight, heightened accountability for harvesters, and enhanced global cooperation have been pivotal in fostering these positive dynamics. Concerning trends, however, emerged towards the beginning of the current decade, indicating potential instability within the legal framework of the crab industry. Persistent statistical discrepancies in trade with South Korea, diminishing institutional capacities within Russia to combat shadow activities, and heightened media scrutiny of illicit crab harvesting underscore the need for sustained vigilance in addressing both internal and external dimensions of this multifaceted problem.
