Decision Support to Sustainable Management of Bottom Trawl Fleet
A decision support concept (DSC) for sustainable management of the bottom trawl fleet was created in line with ecosystem-based management. It is based on principles that integrate ecological, social and techno-economic aspects of trawl fisheries in a multicriteria analysis approach. For the sake of greater transparency and improved stakeholder participation, elements of the proposed multicriter...
متن کاملA simplified model for bottom trawl fishing gears
Computational modeling is a valuable complementary tool to assess behavior of bottom trawl fishing gears. A simplified model of the gear that mainly affects to the net is proposed. The model is constrained to steady towing conditions, flat seabed and gear symmetry. Simulations proportionate a number of relevant outcomes like distribution of tensions at the warp, balance of forces at the otterbo...
متن کاملGeostatistical Assessment of Sampling Designs for Portuguese Bottom Trawl Surveys
New sampling designs for the Autumn Portuguese bottom trawl survey (ptBTS) were investigated to explore alternative spatial configurations and possible increments on sample size. The currently used stratified random design and five proposals of systematic based designs were assessed by a simulation study, adopting a geostatistical approach based on likelihood methods of inference. The construct...
متن کاملA dataset from bottom trawl survey around Taiwan
Bottom trawl fishery is one of the most important coastal fisheries in Taiwan both in production and economic values. However, its annual production started to decline due to overfishing since the 1980s. Its bycatch problem also damages the fishery resource seriously. Thus, the government banned the bottom fishery within 3 nautical miles along the shoreline in 1989. To evaluate the effectivenes...
متن کاملSpecies composition in the Carangidae family during dark and light periods using the bottom trawl survey
The study aimed to estimate the effect of ecological factors such as day and night on catch species composition in fishing landings in the perisan Gulf in May 2016. In this study, were catched about 34937.18 kg marine speceis and identified of 64 groups of species and family including 56 groups of bonyfishes, 6 groups of invertabrate, 2 groups of cartilage fishes. Meanwhile, the Bushehr, Hormoz...
