Abstract :
Abstract This study was performed in 1999. A series of 4 cruises were conducted by R/V Ferdows 1. The studied area was from Meidani (58° 55 E) to Gwatre Bay (61° 30 E) having depths of 10 to 100 m. and divided in to 5 sub regions (A, B, C, D, and E) from west to east which had 30 minutes longitude. Each region was divided in to 4 depth stratum: 10-20, 20-30, 30-50 and 50-100 m. The area of each layer was estimated by plan meter. In each cruises, sampling was carried out for more than 90 stations using a bottom trawler for 1 hours, the following measurements were carried out. Length frequency, length- weight relationship and biomass of 3 fish species of Perciformes such as Pomadasys kaakan, Pampus argenteus and Nemipterus japonicas were estimated by separate depth layers and the studied area. Furthermore, the animal geography distribution of all 3 species were determined, seasonally. The annual biomass of mentioned species was 2413.77, 241.41 and 1263.58 tons, respectively.
