Comparison of the capture efficiency of 0-group fish in pelagic trawls
Precision and relevance of pre-recruit studies for fishery management related to fish stocks in the Barents Sea and adjacent waters. Proceeding of the sixth IMR-PINRO Symposium Bergen, 14-17 June 1994 In 1992 and 1993 experiments were carried out during the international 0-group fish surveys in orde...
