Preliminary analyses of data collected during experimental phases of the 1994/95 and 1995/96 Antarctic crab fishing seasons
Abstract: Data collected from the FN American Champion during Phases 1 and 2 of the experimental ... crab fishery were analyzed with generalized additive models and depletion estimators. Results from the ... generalized additive models show that the density of fishable P. spinosissima is highest off the northern ... coast of South Georgia and at depths between about 100 and 300 fathoms. The Phase 1 results suggest that ...

Updating the Antarctic krill biomass estimates for CCAMLR Subareas 48.1 to 48.4 using available data
, based on data from scientific nets and covering the years between 2000 and 2011. The annual biomass ... variation was significant (CV=73%) but no systematic change in krill biomass was evident during the period ... . The index also suggests that realised exploitation rates were below 0.5% (i.e. catch was <0.5% of ... biomass) and that the potential exploitation rates implied by the operational catch limit (the trigger ...
