Summary In recent years, the trawling industry has shown interest in developing a new trawl that allows the capture of cod, haddock and saithe without bottom impact. This will greatly reduce towing resistance and thus fuel consumption and CO2 emissions. One of the problems with float trawls is that the selection properties of the existing selection systems - ie rigid sorting grids - are reduced when fishing in relatively high densities of fish, which is a prerequisite for profitable float trawl fishing. Through this project, the project team has used all the accumulated knowledge about bottom trawl selectivity (in the North Sea, in the Baltic Sea, and in the Barents Sea) to develop a new selection system, based on flexible net panels (Exit Windows or T90 masks), which can be used in float trawl fishing for cod. haddock and saithe.
Goal: to develop a selection system based on EW or T90 in the float trawl fishery for whitefish.
Sub-goals
• To develop a selection system, based on flexible grid panels (Exit Windows or T90), which has significantly greater sorting capacity than current grating systems, and which reduces the risk to the crew during handling, especially in bad weather.
• To be able to sort undersized fish in front of the back of the trawl bag with the new selection system so that the survivability of fish that are released is enhanced.
• To have a selection system that should be light and easy to handle on deck.
• To develop a specially adapted selection system, using Exit Windows or T90 in fishing for haddock.
• To assess energy consumption when using float trawls.
