Abstract

To find out the composition of the bottom Trawl catch a sampling was used in the Bushehr waters in August and September of 2017. After sampling, the Catch composition was included the species of Jinga Shrimp (Metapenaeus affinis), the Green Tiger Prawn (Penaeus semisulcatus), Kiddi Shrimp (Parapenaeopsis stylifera), or Fiddler Shrimp (Metapenaeopsis stridulans) and Trachypenaeus granulosus. P. semisulcatus with 92. 74% was the dominate species, after it, M. affinis with 6. 7%. Also, CPUA for P. semisulcatus was 49/1045 and for M. affinis was calculate as 57. 87 kg / nm2. The CPUE for P. semisulcatus was estimated 44. 41 ± 17. 05 kg / h. The amount of biomass for P. semisulcatus was 3842. 924 t and for M. affinis was 191. 43 t. A total of 3320 fish including 25 species were caught in this study. Of these 25 species, G. poieti with 25. 2% was the most frequent and A. obricus with 0. 12% had the lowest catch. Also, G. poieti, N. japonicus, D. punctate, S. crumenophthalmus, C. talamparpides and N. peronei with 100 percent occurrence were the most frequent species and N. thalassina has the smallest abundance. The S. commersonnianus with a average length of 59. 13 cm has the highest length and S. insidiator with 7. 75 cm has the smallest length. Generally, the density of P. semisulcatus in the eastern part of the province, as well as in the western part, is the lowest and its abundance is moderate in medium and high depths. Therefore, we can say that its distribution is horizontal.
