1. Towards the development of a stock assessment for Patagonian toothfish in Division 58.4.4, SSRU C on Ob and Lena Banks

   Abstract:  Following the advice from the CCAMLR Working Group in WG-SAM in 2012, a preliminary ... -length model. In this preliminary assessment, the model was started in 1990 and catch, proportions at ... length in the catch, and recapture data from SSRU C from 2007/08 to 2011/12 were fitted in the model. The ... suggest suitable fits to the data, however, there appears to be a pattern of increasing YCS over the time ...
