The losses of Greenland halibut (<i>Reinhardtius hippoglossoides</i>) and two crab species (<i>Lithodes aequispina</i> and <i>chionoecetes angulatus</i>) during deep-sea net and longline fishery in the Okhotsk Sea
The losses of Greenland halibut (<i>Reinhardtius hippoglossoides</i>) were assessed as the amount of discarded fish (in weight relative to the total amount of catch) during deep-sea fishery using bottom nets and long-lines in the Okhotsk Sea. It was shown that, due to various reasons, losses amounted approximately 37% during bottom net fishery and 23,4% during long-line fishery in 2007 years. These losses should be considered in support of the Total Allowable Catch estimates for Greenland halibut. Significant losses were also encountered during bottom net fisheries for golden king crab (<i>Lithodes aequispina</i>) and deep-sea tanner crab (<i>Chionoecetes angulatus</i>). The losses of each crab species reached 20-25%.
