Nemipterid fishes are considered as one of the commercial fish family having considerable catch amount in the Persian Gulf and Oman Sea. There was an annual monitoring survey during 2003-2013 in the Oman Sea using a research bottom trawler for stock assessment purposes. The whole area was stratified into five strata (or sub region) and four depth layers of 10-20, 20-30, 30-50, 50-100 m. The results showed that the best fishing ground for this family were both in western and eastern study area of the Oman Sea, Sistan-o-Baluchistan Province. Amongst five classified sub regions, the Meidani, Galak, Rabech and Biahi in the western part showing the most density with CPUA value of 293.7 kg/km². A comparison between different covered depth layers, it was found that the highest CPUA (331.2 kg/km²) belonged to the depths more than 30 m and with decreasing depth there was a descending trend in catch per unit area value with the lowest value for 10-20 m depths (28.6 kg/km²). This 10 years data show the important finding of increasing of density and catch per unit of area of Nemipterid fishes.
