Ziel der Reise / Objectives of Cruise:

During the FFS Solea cruise SO687, we met the technical challenge of achieving an alternative size selection pattern for trawl gears. For this purpose, an experimental gear was designed with alternative technical solutions to simultaneously avoid catches of the smallest and largest fish available in the targeted population. The design of the experimental gear attempted to achieve three different selective events occurring when a fish encounter the trawl : 1. the fish can escape when it is too big (e.g. guided out of the net) 2. the fish can escape when it is too small (e.g. escape through codend meshes) , or 3. the fish is caught when medium sized The main aim of the present study is to widen the horizon for size selectivity in trawl gears, by demonstrating that alternative selectivity patterns for trawls in general are feasible through new developments in fishing technology .
