1. Models of tag shedding for double tagging as a function of time at liberty and approximate solutions for the single tagging model in CASAL

   Abstract:  The model of tag shedding implicit in CASAL is that of Kirkwood and Walker (KW) (1984 ... ) which models the annual tag shedding (i.e. loss) rate as a constant for individual tags. The CASAL ... software applies this model correctly for fish released with a single tag but does not have the facility at ... present to correctly apply the KW model for fish released with two tags. The solution of Dunn et al. (2005 ...

2. 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.
