A new method for estimating the abundance of Patagonian toothfish (Dissostichus eleginoides)

The Patagonian toothfish Dissostichus eleginoides has been the subject of a rapidly expanding longline fishery in the Southern Ocean, Traditional methods of estimating stock size have proved difficult to apply because the fish are found on the continental slope at depths of 1000 m. During September...

Description
Summary:The Patagonian toothfish Dissostichus eleginoides has been the subject of a rapidly expanding longline fishery in the Southern Ocean, Traditional methods of estimating stock size have proved difficult to apply because the fish are found on the continental slope at depths of 1000 m. During September 1997, the Aberdeen University Deep Ocean Submersible (AUDOS) was used to estimate numerical density and size of toothfish in waters around South Georgia and the Falkland Islands. These are the first estimates that are independent of the commercial fishery
