6. 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 ...

7. INCORPORATING SAMPLING VARIATION AND RANDOM READER ERROR INTO CALCULATION OF EFFECTIVE SAMPLE SIZE IN THE APPLICATION OF AGE LENGTH KEYS TO ESTIMATION OF CATCH-AT-AGE PROPORTIONS

   observations that contribute to the objective function via a multinomial likelihood. The multinomial likelihood ... an effective sample size (ESS) that can be used as the nominal multinomial sample size. The method ... accounts for both the variation associated with sub-sampling of the random length frequency (LF) sample for ... ageing, and random reader error when ageing fish.
