Potential impact of harvesting on Tanner crab ( Chionoecetes bairdi ) on state of its commercial stock off the coast of Kamchatka
Potential impact of landing on the stock and biological state of Tanner crab is analyzed for two fishery districts at Kamchatka in 2013-2020. In the Kamchatka-Kuril fishery subzone, the number of commercial males without limbs and with old shell increased in catches that may be associated with activ...
