Elasmobranch bycatch in the Italian Adriatic pelagic trawl fishery
Elasmobranchs are among the most threatened long-lived marine species worldwide, and incidental capture is a major source of mortality. The northern central Adriatic Sea, though one of the most overfished basins of the Mediterranean Sea, supports a very valuable marine biodiversity, including elasmobranchs. This study assesses the impact of the northern central Adriatic pelagic trawl fishery on...
متن کاملCan South Africa Afford to Become Africas First Welfare State?
This paper assesses the economy-wide impact of implementing and financing a universal or basic income grant (BIG) in South Africa. The various financing scenarios suggested by the proponents of the grant are presented, and these are compared using an applied general equilibrium model for the South African economy. The results indicate that the required changes in direct and indirect tax rates n...
متن کاملDevelopment of a bycatch reduction device (BRD) for shrimp beam trawl using flexible materials
This study aimed to design a bycatch reduction device (BRD) for shrimp beam trawl, which is manufactured by flexible materials to reduce bycatch for the gear in the South Sea of Korea. The model test was carried out to understand the shape of the gear in the water and to measure the variation of flow speed due to the BRD in a circulating water channel. Catches were compared between a shrimp b...
متن کاملA ‘Simple Anterior Fish Excluder’ (SAFE) for Mitigating Penaeid-Trawl Bycatch
Various plastic strips and sheets (termed 'simple anterior fish excluders'-SAFEs) were positioned across the openings of penaeid trawls in attempts at reducing the unwanted bycatches of small teleosts. Initially, three SAFEs (a single wire without, and with small and large plastic panels) were compared against a control (no SAFE) on paired beam trawls. All SAFEs maintained targeted Metapenaeus ...
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...
