برآورد حجم توده زنده و پراكنش ميگوي ببري سبز (Penaeus semisulcatus) در آب هاي حوزه جنوبي استان بوشهر (خليج فارس)

Estimating the biomass and distribution of Penaeus semisulcatus in the Southern water of Bushehr province (Persian Gulf

حجم توده زنده و پراكنش ميگوي ببري سبز در آب هاي حوزه جنوبي استان بوشهر در سال 1393 مورد بررسي قرار گرفت. CPUE كل ميگوي ببري سبز 264/313 كيلوگرم بر ساعت محاسبه شد. تفاوت معني داري در ميزان CPUE ميگوي ببري سبز در بين مناطق مختلف و لايه هاي عمقي مشاهده نشد (0/05

he 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.
