Preliminary investigations of an assessment model for skates and rays in the Ross Sea
Antarctic skates in SSRUs 88.1H, 88.1I, 88.1J, & 88.1K of the Ross Sea. The developmental model ... attempted to create a catch history of all skates and rays in the Ross Sea, and integrate these data with ... assessment model. We conclude that aspects of the catch history were very uncertain, including the species ... composition, the weight and number of skates caught, the proportion discarded, and the survival of those ...
