Estimating unaccounted fishing mortality in the Ross Sea region and Amundsen Sea (CCAMLR Subareas 88.1 and 88.2) bottom longline fisheries targeting Antarctic toothfish
. However, fish that are captured by fishing gear that is not subsequently retrieved are generally not ... unaccounted fishing mortality from lost lines in these fisheries is provided. These estimates suggest that on ... average 208 tonnes of Antarctic toothfish mortality may be unaccounted for annually. While the current ... estimates may be improved through the adoption of better data reporting practices, these estimates were ... loss rate within a spatial cell multiplied by the number of sets with positive hook loss in that cell ... be adjusted upwards to account for higher catch rates associ- ated with longer soak times.
