Focusing on under 10 m gill nets in the south west of England, the project sourced and analysed extensive fisheries data sets, conducted interviews with skippers and organised a workshop of expert stakeholders including fishermen, scientists, policy makers and fisheries managers. These activities were used to evaluate the impacts of large mesh gill nets according to selectivity for target species, selectivity for size, impacts on unwanted by-catch species including mammals and birds, impacts on habitats and economic returns from haddock.

Discards are mainly associated with fish that are damaged by seals and lice, and lack of quota. Skippers completing the questionnaire also stated that by-catches of marine mammals and birds using large mesh gill nets are rare. These claims were consistent with third party photographic and video material, which showed little evidence of habitat damage (i.e. material hauled up in the gear). Fuel use per trip was also found to be low. Participants at the stakeholder workshop agreed that fishing with large mesh gill nets is a ‘clean’ fishing method and should be treated as a low risk fishing technique as far as enforcement of the landing obligation is concerned (Jan 2016 onwards). Over 10m trawler operators argued that they were developing more selective methods to eliminate haddock discards since haddock would be a choke species when the landing obligation commences. Any less haddock quota would therefore have a big impact upon their fishing operations. Policy makers and fisheries managers recognise that large mesh nets are highly selective for haddock. However, quota will always be perceived to not be enough and if more quota is given to one part of the industry then it would have to be taken from another part of the industry. MEDIN 3.1.1
