Extending ecological monitoring to underpin the development of feedback management approaches for the Antarctic krill fishery
Abstract: CCAMLR has agreed to consider and develop a feedback management approach for the krill ... fishery. Such a management approach may also require the development of a new or extended monitoring ... programme for dependent species, especially if the krill fishery is to operate over large spatial scales and ... in areas where no existing monitoring, including CEMP monitoring, is present. Here we consider some ...

IS THE BYCATCH OF VULNERABLE INVERTEBRATE TAXA ASSOCIATED WITH HIGH CATCH RATES OF FISH IN THE ROSS SEA LONGLINE FISHERIES?
by fishing activities requires knowledge of the distribution of those communities relative to the ... locations. This study used the catch of VME indicator organisms reported during the 2008/09 Ross Sea ... on a set-specific basis. Analysis of the data available showed that vessel and longitude were ... significant factors in predicting the VME indicator organism catch rate. Toothfish catch, when forced into the ...
