Towards the development of a stock assessment for Patagonian toothfish in Division 58.4.4, SSRU C on Ob and Lena Banks
assessment of stock status of D. eleginoides in SSRU C in Ob-Lena Banks was made using a CASAL catch-at ... -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 ... current model is the historical IUU catch. The current model only includes the catch history since 2007/08 ...
