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 ...

Estimating fishing gear selectivity for trawlers using length-frequency data from concurrent commercial trawl and longline fishing for Patagonian toothfish in Division 58.5.2 and the ratio of their hazard functions
Abstract: The upper-arm of the length-dependent fishing selectivity function for trawlers fishing ... for Patagonian toothfish around Heard Island (Division 58.5.2) was modelled as the exponential of a ... from commercial operations of each of trawlers and longliners fishing concurrently for 3 seasons ... assuming that, for the upper range of lengths, fish are fully selected by longliners but not by trawlers ...

An alternative method for estimating the level of illegal fishing using simulated scaling methods on detected effort
this new method are similar to those of the Agnew and Kirkwood (2005) method, and this suggests that ... the current method is adequate under circumstances of low evasion and when good knowledge exists that ... zero observations reflect zero illegal fishing. The new method performs better in the case of zero ... detections and can potentially better handle the evasion of detection by illegal activity. Both the new and ...
