CPUE, CPUA and biomass of Pomadasys kaakan in the waters of Bushehr province (Persian Gulf)

The CPUE, CPUA and biomass of Pomadasys kaakan was assessed in the waters of the province of Bushehr in 2011. The study area was divided into three areas (Northern, Central and Southern) and depth zones (10-20, 20-30 and 30-50 m).Stratified random sampling was used to collect the data. Samples were taken from 45 stations. The total length and total mean length were calculated to be 27-56 cm and 42.7±4.95 cm, respectively. The total biomass was estimated to be approximately 5943.55 tons. The total CPUE and CPUA were calculated as being 803.25 kg/h and 9269.05 kg/nm2 , respectively. The lowest mean CPUE was observed in the 20-30 m depth zone and was 8.82 kg/h and the highest mean CPUE was observed in the 10-20 m depth zone as 21.45 kg/h. The lowest and highest mean CPUA were calculated in the 20-30 m and 10-20 m depth zones as being 95.91 kg/nm2 and 259.35 kg/nm2 , respectively. Also, the central area of Bushehr showed the highest CPUA with an estimate of 8913.9 kg/nm2 . The results of this study demonstrated that the highest distribution and biomass of P. kaakan were concentrated in central areas and 30-50 m depth zones.
