Abstract

The biomass and distribution of Penaeus semisulcatus were investigated in the Southern water of Bushehr province in 2014. Total CPUE of Penaeus semisulcatus was calculated 264/313 kg/h. There was no significant difference in CPUE of Penaeus semisulcatus indifferent regions and depth layers (P>0.05). From the depth layers and various regions, maximum mean CPUE were observed in 10-20 m layer zone with 10.92±3.21 kg/h and Rase Khan to Motaf region with 15.35±3.88, respectively. There was no significant difference in mean CPUE of Penaeus semisulcatus indifferent regions and depth layers (P>0.05). Total CPUA of Penaeus semisulcatus was calculated 1460 kg/nm2. CPUA did not differ significantly between various regions and depth layers (P>0.05). Total biomass of Penaeus semisulcatus was estimated 524 tons in the entire study area. Maximum biomass was estimated in Rase Khan to Motaf region with 389 tons and 20-30 m layer zone with 205 tons.
