Comprehensive catch data are fundamental to support the sustainable management of large pelagic fisheries. However, reported by Indian Ocean Tuna Commission (IOTC) on behalf its member countries currently under-represent extent these fisheries in Ocean. We reconstructed catches species for from 1950 2020, aiming improve comprehensiveness existing and provide more ecologically relevant datasets ...

Depredation by cetaceans on fisheries is a major issue globally, both in terms of conservation and economics. The present study conducted Cyprus, Eastern Mediterranean Sea, aimed to understand the extent, level, type cetacean depredation albacore tuna pelagic longline fishery, particular quantify evaluate economic consequences identify potential dolphin-longline conflict areas mitigation practi...

We studied age, growth, and maturity of the oceanic whitetip shark Carcharhinus longimanus in the North Pacific, and the reproduction in the North and South Pacific, captured with tuna longline from Nov. 1967 to Oct. 1995. Vertebral rings were examined from 111 males (precaudal length: 54-172 cm) and 114 females (precaudal length: 50-195 cm). Minimum and maximum numbers of translucent rings wer...

This paper summarises key findings from several experiments to determine the most effective branch line weighting options for pelagic longline fisheries. Initial (0-2 m deep) and overall sink rates of a range of line weighting options – each comprising a different combination of weight and leader length (distance between hook and weight) – were compared and several options identified that offer...

Introduction Longline fishing gear has a higher by-catch rate than any other type of commercial gear. Nowadays, there is an urgent need to find efficient management strategies mitigate and the use new hook types could be one them. This study investigates effects longline fishery (which targets swordfish, Xiphias gladius , in South Adriatic Sea) replacing traditional J-type with circle (C-type h...

—The biomass levels of several target species of the Atlantic pelagic longline fishery, including various tunas of the genus Thunnus and swordfish Xiphias gladius, are estimated to be close to those required to support the maximum sustainable yield. In contrast, several species captured incidentally are severely depleted. Live release of incidental catch is one means of reducing the fishing mor...
