![]() This is an effective way of catching shrimp and has less impact on the sea floor than the beam trawl. This method of fishing has a lot of by-catch and a ‘seaflap’ is often used to reduce this amount of by-catch. Instead of tickler chains, they use a rope with rubber bobbins that roll over the sea floor to scare the shrimp. Shrimp trawlĪ shrimp trawl is a light-weight form of the beam trawl. This method has a large amount of bycatch, a considerable impact on the sea floor, and a high fuel usage. The fish are startled up from the sea floor with steel ‘tickler chains’ that rake through the sea floor. These shoes glide over the sea floor while fishing. This beam is supported by ‘shoes’ on either side. In these trawls the horizontal opening of the net is provided by a beam, made of wood or metal, which is up to 12 m long. ![]() Beam trawlsĪ beam trawl net consists of a cone-shaped body ending in a bag or codend, which retains the catch. Several methods using trawl nets are listed below. The opening of trawl nets can be held open in many different ways. ![]() ![]() When this occurs in a fishery, it is called a mixed fishery as not only the one target species is caught. Bottom dwelling species often live in mixed groups, so not only the target species are caught but also other kinds of species end up in the net. This catching method is widely used in the fishery on whitefish (like cod, whiting, and haddock) and flatfish (like sole and plaice). The trawls are towed from the sides or the rear of the boat. Trawl nets are cone shaped nets that end in codends, which are dragged through the water column and over the sea floor. ![]()
