Estimation of natural mortality using catch-at-age and aged mark-recapture data: a simulation study comparing estimation for a model based on the Baranov equations versus a new mortality equation
-recapture data were generated for 12 years of fishing. Two alternative estimation models were programmed in ... R. Both use the same Poisson likelihood for annual number of recaptures by age class, and both model ... the age-structured population for each fishing year by annual recursive use of difference equations ... realistic. In simulation studies of multiple years of releases, both the BODE and CCODE models gave accurate ...
