Midwater trawling is trawling, or net fishing, at a depth that is higher in the water column than the bottom of the ocean. It is contrasted with bottom trawling.
Midwater (pelagic) trawling is a much "cleaner" method of fishing, in that the catch usually consists of just one species and does not physically damage the sea bottom. However, environmental groups have raised concerns that this fishing practice may be responsible for significant volumes of by-catch, particularly cetaceans (dolphins, porpoises ...
A number of the Cape's small boat fishermen, whale watch captains, and fishing charter operators blame midwater trawlers for depletion of herring stock. That depletion, they claim, has had a ...
A fishing trawler is a commercial fishing vessel designed to operate fishing trawls. Trawling is a method of fishing that involves actively dragging or pulling a trawl through the water behind one or more trawlers. Trawls are fishing nets that are pulled along the bottom of the sea or in midwater at a specified depth. A trawler may also operate ...
Trawling occurs mainly over sandy sediments, but areas of muddy substrate and coarser, gravely substrates are also trawled. [4] A five-year benthic trawl experiment was implemented between 2014 and 2019 with the purpose of determining the environmental impact of demersal trawling in South African waters.
Bottom trawling is trawling (towing a trawl, which is a fishing net) along the seafloor. It is also referred to as "dragging". The scientific community divides bottom trawling into benthic trawling and demersal trawling. Benthic trawling is towing a net at the very bottom of the ocean and demersal trawling is towing a net just above the benthic ...
European seabass (Dicentrarchus labrax), once target of a pair-trawl fishery in the English Channel, now banned due to the high level of cetacean bycatch. Pair trawling is a fishing activity carried out by two boats, with one towing each warp (the towing cables).
A Florida tree trimmer has died after getting caught in a wood chipper. The tragic accident occurred at around 9:30 a.m. on Tuesday, Jan. 28 as a contracted tree trimming vendor was working at ...
