  • Selection efficiency of encircling grids in a herring pontoon trap
  • 2011

  • Journal article (peer-reviewed)abstract
    • High bycatches of undersized herring constitute a major problem in the Baltic Sea herring trap fishery. In an attempt to reduce these bycatches, this field study evaluates the efficiency of rigid selection grids encircling a herring pontoon trap. The results show that 54-72% of the undersized herring were removed from the catch. The introduction of such grids would therefore represent a significant step towards a more efficient and sustainable herring fishery in the Baltic Sea. © 2011 Elsevier B.V.

  • Size selection of herring (Clupea harengus membras) in a pontoon trap equipped with a rigid grid
  • 2011
  • In: Fisheries Research. - : Elsevier BV. - 0165-7836 .- 1872-6763. ; 108:1, s. 81-87
  • Journal article (peer-reviewed)abstract
    • A sustainable fishery in the Baltic and Bothnian Seas requires the development and introduction of fishing gear which fishes selectively and at the same time excludes raiding seals. The purpose of this study was twofold: firstly to test and evaluate rigid grids as a method for retaining only larger herring in a pontoon trap, and secondly to analyze which factors were influencing the selection process. The results demonstrate that it is indeed possible to sort herring by size in a pontoon fish chamber. The efficiency of excluding undersized herring was at best 27%, using a selection grid covering just over 0.1% of the fish chamber wall. The factors which have most effect on the selection were the quantity of fish in the trap, the season of the year, the time of day and the presence of seals. (C) 2010 Elsevier B.V.
