Results of the 2012 eastern Bering Sea upper continental slope survey of groundfish and invertebrate resources

This report provides estimates of biomass in metrictons (t), population number, and catch per unit effort (CPUE; no./ha and kg/ha) for all taxa identified on the survey. Size frequencies (42 species) and CPUE distribution plots (41 species) are presented for the most abundant species or species of commercial interest. The five fish species with the greatest survey biomass were giant grenadier (Albatrossia pectoralis), Pacific ocean perch (Sebastes alutus), arrowtooth flounder (Atheresthes stomias), popeye grenadier (Coryphaenoides cinereus), and walleye pollock (Theragra chalcogramma)
