A 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 کاملcatch composition of the bottom trawl fishery along the coasts of karataş-adana (northeastern mediterranean sea)
the catch composition of the bottom trawl fishery along the coasts of karataş was evaluated in the 2002-2003 fishing season. a total of 110 species were registered, the fishes showed the highest diversity (90 species) followed by 15 crustaceans species and 5 species of cephalopods. the highest catch per unit effort (cpue) value (66.8 kg h -1 ) was recorded in september when the fishing season w...
متن کاملThe effects of 118 years of industrial fishing on UK bottom trawl fisheries.
In 2009, the European Commission estimated that 88% of monitored marine fish stocks were overfished, on the basis of data that go back 20 to 40 years and depending on the species investigated. However, commercial sea fishing goes back centuries, calling into question the validity of management conclusions drawn from recent data. We compiled statistics of annual demersal fish landings from botto...
متن کاملAfricas Role in Multilateral Trade Negotiations
1846 Countries in Sub-Saharan Africa won fewer concessions on their exports in the Uruguay Round than did other developing countries, but they still emerged facing fewer or lower restrictions than others. They should be more active in the next Round, focusing negotiations not on trade preferences but on bound most-favored-nation tariff reductions. Summary findings Openness and liberal trade pol...
متن کاملThe Use of Gis to Analyse the Spatial Distribution of Fishing Effort in Coastal Fishery
Based on two models focussing on the analysis of the spatial components of the fishing effort distribution, we present a global approach which has been formalised in order to develop a computerized simulation tool called FAST (Fishing Activity Simulation Tool), distributed as an extension of ESRI ArcView GIS Software. FAST defines a logical framework under which the knowledge about fishing effo...
