Marine wild-capture fisheries depend on the capacity of ocean to provide a flow harvestable resources sustain industry. Paradoxically, conventional fishing often undermines these by degrading environment and overexploiting fish stocks. Many UK have declined for over century due biased focus their social-economic value lack recognition that they are social-ecological systems need be managed as s...

The current harvest policy for the Pacific halibut fishery uses a 32-inch minimum size limit in the directed commercial fishery, and total annual catches in each of the eight regulatory areas are based on area-specific exploitation rate targets. In nondirected fisheries retention of halibut is prohibited. Post-release survival rates are gear dependent and partially based on observer accounts of...

Here we present a case study toward producing quantitative scientific advice on the application of the EU Common Fisheries Policy (CFP) in the Black Sea. We provide estimates of fishing mortality rates at levels which will lead to rebuilding and maintaining stocks above biomass levels that could produce maximum sustainable yield (MSY) under the IPCC RCP4.5 future climate scenario together with ...

Penelitian ini bertujuan untuk mengetahui tingkat pemanfaatan ikan tuna yang didaratkan di PPP Carocok Tarusan belum mencapai potensi sumber daya berkelanjutan (MSY) optimal dan masih memungkinkan ditingkatkan hasil tangkapannya berdasarkan kegiatan penangkapan. Berdasarkan penelitian, hubungan antara effort CPUE menunjukkan bahwa sumberdaya pernah mengalami overfishing pada tahun 2018, 2019 20...

Climate change is projected to cause significant reductions in global fisheries catch during the 21st Century. Yet, little understood of climate impacts on tropical fisheries, which support many livelihoods, as case Western Indian Ocean region (WIO). Here, we focus two central WIO countries ― Kenya and Tanzania run a multi-species fish model (Size Spectrum Dynamic Bio-climate Envelope Model; SS...

The oceans are by far the largest carbon sink and estimated to have absorbed roughly 40 percent of anthropogenic dioxide emissions since beginning industrial era. climate services performed can be described as an interaction between a physical biological pump. Whereas role pump is well established, full scale provided has only recently been understood. This made up different marine species, fro...

Abstract. Providing reliable observations of aerosol particles' absorption properties at spatial and temporal resolutions suited to climate models is utter importance better understand the effects that atmospheric particles have on climate. Nowadays, one instruments most widely used in international monitoring networks for situ surface measurements light multi-wavelength dual-spot Aethalometer,...

The silver scabbardfish Lepidopus caudatus is a mesopelagic species living on the shelf and slope down to 600 m in temperate seas all around world. In Mediterranean, caught mainly by longlines with marked seasonality. early 90s Strait of Sicily (Central Mediterranean Sea), new fishery targeting L. was developed. This uses an ad hoc pelagic trawl gear called “ spatolara .” Vessels using have inc...
