The By-catch Composition of Shrimp Trawl Fisheries in Bushehr Coastal Waters, the Northern Persian Gulf
This paper is a comprehensive study of the shrimp trawl by- catch from Bushehr coastal waters (N. Persian Gulf). Sampling operation was carried out in two shrimp fishing seasons using the (Saber and Jahanara) commercial trawlers Generally, 87.5% of the total catch was by-catch and 12.5% was target species (shrimp). The catch composition included: 114 species from 45 teleostei families, 13 speci...
full textThe catch per unit of effort catch per unit of swept area and biomass of Threadfin Bream (Nemipterus japonicus) by swept area method in coastal waters of bushehr province
The aim of this study was to investigate and estimate the CPUE (Catch Per Unit of Effort), CPUA (Catch Per Unit of Swept Area), biomass and length frequency of Threadfin Bream (Nemipterus japonicus) in Coastal waters of Bushehr. This study was carried out in March 2011. The study area was divided into three area (Northern, Central and Southern) and depth zones (10-20, 20-30 and 30-50 m) and str...
full textSpecies diversity and catch per unit effort (CPUE) of Gobiidae in Salmanshahr, coastal area of the southern Caspian Sea
The gobies are non-commercial fishes in the Iranian waters of the Caspian Sea for which population dynamics and stock status are poorly known. In this survey, we tried to define species diversity and catch per unit effort (CPUE) of Gobiidae by using beach seine nets in Salmanshahr, the southern Caspian Sea. From March 2011 to April 2012, 224 specimens representing 4 gobiid species, belonging to...

full textAssessment of species composition and CPUE (catch per unit effort) of commercial fish caught with bottom gillnet in Jask coastal waters
Tiger– toothed croaker (Otolithes ruber) is considered as a commercially important target species for fishermen in south of Iran, due to its high economic value and marketability. This investigation was carried out using bottom monofilament gillnet with mesh size (stretch mesh) of 8.5 cm and net height of 6 m, made of nylon twine (Polyamide) and a hanging ratio of 50% in order to determine spec...
