Report of the Workshop on Standard Trawls for Baltic International Fish Surveys

The first Workshop on Standard Trawls for Baltic International Fish Surveys was held in Gdynia, Poland 8-10 January 1997. The Workshop found it not possible to select a single fishing gear that is optimal to cover all the species and size classes presently assessed in the Baltic Sea, considering also the two size classes of research vessels operating in the area and the much varying bottom topography to be covered. The Workshop presented in its report (Anon., 1997a) three options, giving details on ground-gear construction, netting material, mesh sizes, bridles, sweeps, trawl doors, and so on.
