Abstract

Sepia pharaonis and Trichiurus lepturus are two species target catch of Bottom Trawl. These two species because of the value of export and money are very important economically. This study Biomass and the mean Catch per Unit of Area (CPUA) Sepia pharaonis and Trichiurus lepturus of Bottom Trawl fisheryfrom Oman Sea (Sistan and Balochestan province coastal waters) were investigated. Data were collected in one research cruise by using R/V Ferdows-1 during September and October 2016. The study area was stratified into 5 strata (M to Q) and 4 Substratum covering the depths of 10-20, 20-30, 30-50 and 50-100 m in the Oman Sea. A total of 92 stations were randomly selected and the biomass and CPUA were estimated by swept area method. Result indicated that maximum and minimum the mean CPUA of Sepia pharaonis was 894. 0 Kg. nm-2 and 64. 1 Kg. nm-2 in the region M and Q respectively. Maximum and minimum the mean CPUA of Trichiurus lepturus was 2485. 3 Kg. nm-2 and 49. 9 Kg. nm-2 in the region N and Q respectively. Maximum and minimum biomass of Sepia pharaonis was estimated 240. 3 tons and 46. 6 ton in the region P and Q respectively. Maximum and minimum biomass of Trichiurus lepturus was estimated 899. 3 ton and 21. 7 tons in the region N and M respectively. Also maximum and minimum the mean CPUA and biomass of Sepia pharaonis and Trichiurus lepturus were obtained in depth of 50-100 m and 10-20 m respectively. Result this study is useful for management of these two species resources from of Oman Sea.
