Species Associations and Day-night Variability of Trawl-caught Fishes from the Inshore Sponge-coral Habitat, South Atlantic Bight!
Biomass, species composition, diversity, and community structure of demersal fishes were studied during the spring of 1978 in the sponge-coral habitat of the South Atlantic Bight. These results were compared with sampling at an open-shelf site. Otter trawl catch rates were an order of magnitude higher in the sponge-coral habitat than at the open-shelf site. Density and biomass estimates in the ...
متن کاملJob Satisfaction in the Shrimp Trawl Fisheries of Chennai, India
Shrimp trawling represents an important fishing métier in South India, generating high levels of employment and economic value. It is also a contested métier, ostensibly contributing to environmental degradation and social inequality. This paper investigates the job satisfaction of crew members (captains and workers) on board the shrimp trawlers of Chennai (former Madras). Research took place i...
متن کاملThe 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...
متن کاملQuantifying the Escape Mortality of Trawl Caught Antarctic Krill (Euphausia superba)
Antarctic krill (Euphausia superba) is an abundant fishery resource, the harvest levels of which are expected to increase. However, many of the length classes of krill can escape through commonly used commercial trawl mesh sizes. A vital component of the overall management of a fishery is to estimate the total fishing mortality and quantify the mortality rate of individuals that escape from fis...
متن کاملBycatch of lined seahorses (Hippocampus erectus) in a Gulf of Mexico shrimp trawl fishery
Bycatch studies have largely ignored population level effects on fish species of little commercial interest. Here we analyze bycatch of the lined seahorse (Hippocampus erectus) in the bait-shrimp trawl fishery in Hernando Beach, Florida, providing the first fisheries data for this species. Based on catch per unit of effort (CPUE), size, sex, and reproductive status of trawled H. erectus, 1) app...
