SGTCOD has conducted a large number of studies both theoretical and experimental, and most sea investigations are carried out using German research vessels. For the Baltic Sea cod trawl fishery, the work concentrates mainly on finding a best solution for T90 and T0 (diamond) codends, as well as the Bacoma codend Baltic cod fishing. For T90 codend we have studied the effect of turning netting, the number of meshes, and twine construction, among others. The results are evaluated and conclusions are introduced into subsequent sea studies.
The group has had three meetings: Ancona, Italy 2009; Hirtshals, Denmark 2010; and Reykjavik, Iceland 2011.
