This research was carried out to assess the effect of depth on distribution pattern, on density, and Catch Per Unit Area (CPUA) of Nemipteridae family in Oman Sea. Sampling was carried out using Ferdose I investigative vessel by trawl floor in cape of meydani (55° 58) east to Govater (61°25׳) east in the waters of the Oman Sea (Sistan and Baluchistan) in September-October 2013 (during 25 days). The whole sampling area was divided into five regions (A, B, C, D, E), with depth layers of 10-20 m, 20-30 m, 30-50 m and 50-100 min a total 82 trawl stations. The highest biomass and CPUA of Nemipteridae were recorded in the stratum D (Kenarak,Chabahar, Ramine-Kijdof) approximately 1075.5 tons and 2002.8 kg/nm², respectively. Moreover, the highest biomass and CPUA were observed in depth layer of 30-50 approximately 919.8 tons and 2641.9 kg/nm², respectively. Finlay the distribution map of this family was drawn with Arc-GIS version 9.3 software. The results showed that the main habitat of this family is D station (Kenarak,Chabahar, Ramine-Kijdof) in depth 30-50 m that can be affected by several factors such as food abundance and environment factors.
