Flexibles Gitter für die Größenselektion von Ostseehering
In the Institute for Fishery Technology in Hamburg a new sorting grid for herring trawl fishery was developed which is more adapted to the commercial fishery than existing constructions. Therefore a flexible design was choosen with braided snoods as grid elements and rubber rings for shape stabilization. First tests were carried out with twin trawlers in the Western Baltic in February 1999. They proved principally the serviceability of this grid construction under commercial fishing conditions. The percentage of small sized herring was essentially reduced. Due to only few hauls more detailed quantitative statements are not possible yet.
