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
. An alternative estimation strategy was tested using simulation whereby catch-at-age and aged mark-recapture data ... mortality equation (CCODE model) uses an ODE with constant within-year catch per unit time for each age ... class, and as a result allows catch to be removed directly from the population. Compared to the BODE ... to achieve their target catch for the year, the CCODE model is the more realistic. In simulation studies ...
