However, fishing was banned in 1979 due to large catches of undersized fish. In connection with an increasing focus on damage to benthic fauna from bottom trawling, the Institute of Marine Research started a three-year NFR project in 2007 to investigate whether the bottom impact can be reduced by taking parts of the cod quotas with pelagic trawls. Compared to the 1970s, the selection in today's trawls is much better (partly due to the larger mesh size in the bag and the use of selection grids) and the legislation has provisions for the protection of juvenile fish (rules on maximum mixing of undersized fish and authority to close areas with a lot of small fish).
In connection with recent fishing trials, a number of new questions have arisen related to pelagic trawling, which it is important to answer in order to document that pelagic trawling for cod, haddock and saithe is in accordance with the principles of responsible fishing and to ensure that fishing becomes profitable. These questions include choice of grating concept, optimal playing distances in grating when fishing for resp. cod and haddock.
Goals:
• To improve the selection capacity of pelagic trawls by using tandem grates and square mesh panels in the trawl bag.
• To determine the optimal playing distance in the grate when fishing for haddock.
• To reduce the loss of commercial size cod.
• To reduce the cladding of the trawl net with solder when using the T90 net line.
• To test catch-limiting devices to avoid catching too large hauls.
• To investigate whether the use of pelagic trawls in cod and haddock fishing can reduce energy consumption per kilo of fish caught and thus improve profitability and reduce emissions of environmentally harmful gases, e.g. NOx.
