Evaluation of the results of trawl selectivity experiments by Poland, Spain and USSR in 1978/79, 1981/82 and 1986/87
Abstract / Description:
Trawl selectivity for several species of Antarctic fish was evaluated taking into account additional data obtained by Poland, Spain and USSR during selectivity experiments in Statistical Area 48 in 1978/79, 1981/82 and 1986/87 seasons. These data comprise different characteristics of experimental codends, length frequency distribution of stocks sampled, catch rates and catch composition. Details of these data were analyzed and minimum mesh sizes for several species were calculated. It is recommended that introduction of these mesh sizes should be considered for commercial fishery in Statistical Area 48.
