The estimate of non-standard size fish (less than LM50) in industrial trawler fishing shrimp in the fishing grounds of the Hormozgan province

This study was conducted to estimating the amount of non-standard sizes (with lengths less than LM50) fishes of shrimp trawls in the Hormozgan Province coastal water during shrimp fishing season. Sampling was carried out using the Tabas otriger commercial trawler during 55 hauls. Eight commercially valuable species including Pampus argenteus، Parastromateus niger، Plicofollis dussumieri، Saurida tumbil، Nemipterus japonicus، Scomberomorus guttatus، Platycephus indicus and Otolithes ruberwere were investigated in this study. S. guttatus (94. 33%)، P. argenteus (93. 19%)، O. ruber (91. 57%)، P. niger (89. 86%)، P. indicus (66. 66%)، S. tumbil (60. 4%)، N. japonicas (35. 38%) and P. dussumieri (4. 42%) had most high non-standard length in catch، respectively. LOPT were calculating for P. dussumieri. The results showed a high pressure on the species of the shrimp trawl that can be the reason of species composition change in the Persian Gulf fisheries.
