THE ENVIRONMENTAL IMPACT OF FISHING
A variety of different fishing techniques are utilised by fishermen. Bottom or demersal trawling is the main capture technique used by Scottish whitefish fishermen and many langoustine and scallop boats and it is estimated that 77% by volume of seafood in the UK is caught in this way.
A typical trawl consists of a bag-shaped net with warps that lead to the fishing boat. The mouth of the net is kept open by trawl doors, which act like pressure boards using the force of the water to cause spread.
Our mackerel and herring fishermen also use trawls, but because these are midwater swimming fish, their nets do not contact the seabed. Shellfish such as crab and lobster are generally caught in creels.
