Regarding to estimate the catch per unit of area (CPUA) and demersal resources biomass in the Persian Gulf and Oman Sea, a series of monitoring research cruises were carried out from 2004 up to 2008 using the R/V Ferdows-1 equipped with stern trawl. The study area was from Khuzestan province in north-west of the Persian Gulf to Sistan-o-Baluchestan province in the east. The results of distribution pattern showed that the best fishing ground was restricted to the east and west of Hormuzgan province with emphasize on Bandar Abbas to Jask region. The next more abundance area belongs to Bushehr province waters due to the vast continental shelf area and also higher catch per unit of area. Amongst five strata of Sistan-o-Baluchestan province waters, the highest biomass and abundance were found in the fishing grounds of Gordeem, Rashedi and Konarak. A comparison between different depth layers, it was found that in the Persian Gulf, there is an ascending trend for biomass and CPUA with increase of depth with the highest values in depths of 30-50m. On the contrary, in the Oman Sea the highest biomass and CPUA were found in lower depths with the maximum value in depths of 10-20m.
