dc.description.abstractDemersal resources in the Gulf of Oman are one of the main objectives for both industrial and traditional fisheries. In order to implement a rational management of these resources; the research project of “stock assessment of demersal resources in the Gulf of Oman” were carried out as a monitoring survey in 2003 The objectives of project were: 1) Identification of catches composition of demersal fishes 2) To estimate the biomass and CPUA of demersal resources 3) To determine the distribution pattern of commercial fishes 4) To determine the ratio of commercial, non-commercial fishes and amount of bycatches The studied area was restricted to the borderline with Pakistan in Gwatr (61 25 E) in the east and strait of Hormuz (57 00 E) in the west and isobath of 100m in the south, covering depths of 10 to 100 m with a total area of 1700 nm2. The R/V Ferdows-1, a stern trawler equipped with a fish bottom trawl was used for sampling. To collect the catch data, 107 stations were selected in a random stratified design distributed in different depths and area. The total area was stratified to 7 primary strata, and 4 different sublayers of 10-20, 20-30, 30- 50 and 50-100 m. The swept area method was used to assess and estimate the amount of biomass and CPUA (catch per unit of effort). The total catch was classified to 3 main groups of: a) The commercial demersal fishes, b) The non-commercial demersal fishes c) The non-demersal group The total biomass of all groups was estimated 88346 tons of which 52478 tons belonged to jellyfishes. In this year there was an unpredictable and high bloom of jellyfishes scattering in all area of the Gulf of Oman. The total biomass of fishes was estimated 35808 tons of which 19391 tons were commercial fishes. Meanwhile the amount of non-commercial fishes was calculated about 15102 tons.en_US
