Significance The incidental catch of threatened species is still one the main barriers to fisheries sustainability. What would happen if we closed 30% ocean fishing with goal reducing bycatch? Analyzing 15 different around globe, found that under static area management, such as classic no-take marine closures, observed bycatch could be reduced by 16%. However, dynamic management based on and closing same total but fragmented in smaller areas can move year year, reduction increase up 57% at...
Since 1991, fishing operations on tuna schools associated with drifting Fish Aggregating Devices (FADs) have become widespread in the purse seine fishery Gulf of Guinea. In offshore South Sherbro area (0–5° N, 10–20° W), FAD-associated catches represent about 75 % total catch. This FAD exploits concentrations skipjack mixed a smaller amount bigeye and yellowfin similar size (46 cm), some large yellowfin. Catches unassociated are mainly composed breeding phase skipjack. Here we studied diet...
Summary Seabirds have been incidentally caught in distant‐water longline fleets operating the Southern Ocean since at least 1970s, and breeding numbers for some populations shown marked trends of decline recovery concomitant with fishing effort within their distributions. However, lacking is an understanding how forms among‐individual heterogeneity may interact fisheries bycatch influence population dynamics. We develop a model that uses comprehensive data on spatial temporal distributions...
The use of fish aggregating devices (FADs) in tropical tuna fisheries has increased significantly during recent decades. Concurrently, concern about juvenile mortality, bycatch, and marine debris associated with FAD increased, this led to the implementation management measures more sustainable designs (e.g., non-entangling or biodegradable FADs, limits on active etc.). This document reviews data collection reporting requirements tuna-Regional Fisheries Management Organizations (t-RFMOs)...
One hundred and fifty-one Centroscyllium fabricii stomachs containing food were analysed on board freezer vessels in north-west Atlantic 1992. Three length groups established to study variations diet with length. The most important prey group was waste products from fish processing by the fleet fish. Diet varied length, smaller specimens feeding crustaceans molluscs, offal forming main larger predators.
