Catch size composition of North Pacific Armorhead (Pentaceros wheeleri) in the Emperor Seamounts by the Korean trawl fishery up to 2019

The North Pacific Fisheries Commission revised the CMM to expand the mesh size of the bottom trawls operating in the Convention Area to 130mm or above from 2019. Korean bottom trawlers have operated from 2013 to 2019. Observer was on board during vessel operation, and the observers randomly measured the total length and weight of North Pacific Armorhead. The catch-length composition of 2019 in which the revised CMM was applied was compared to the catch-length composition in 2018 and that of years prior to 2019. The catch composition in 2019 was larger in size than the other years. The weight over total length of the North Pacific Armorhead was also higher in 2019 than in 2018.
