The Ross Sea toothfish fishery: proposal for conditional transition of classification from exploratory to established
Abstract: The Ross Sea toothfish fishery in Subarea 88.1 and 88.2A&B has been classified by ... CCAMLR as an exploratory fishery since 1998. The current classification of this fishery as ‘exploratory ... ’ has led to the widespread misconception that little information is available for this stock, and that ... a rigorous assessment of the stock status and estimation of long-term precautionary yield has yet to ...

A system-of-equations approach to modeling age structured fish populations: the case of Alaskan red king crab, Paralithodes camtschaticus
-structured populations using trawl survey age/size frequency data. The analysis builds upon a Ricker spawner ... -recruit structure and provides a cohort-based estimation method that retains the underlying dynamic ... properties of a delay-difference model. The framework shares a common spawner-recruit function across age ... -class equations. This exploits the commonality among cohort members and serves as an instrumental ...

Diet and prey consumption of Antarctic petrels Thalassoica antarctica at Svarthamaren, Dronning Maud Land and at sea outside the colony
Abstract: The diet of the Antarctic petrel Thalassoica antarctica was studied during two years at ... Svarthamaren, an inland colony situated in Dronning Maud Land, Antarctica and in the pack-ice outside ... Svarthamaren. The analyses showed that the most important food (wet weight) at Svarthamaren was Crustaceans (68 ... %), followed by fish (29%) and squid (3%), whereas individuals collected in the pack ice took mostly fish (95 ...
