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
Abstract: Attempts to estimate natural mortality, as a single constant M, simultaneously with ... for population numbers at age obtained by integrating a first order ordinary differential equation ... . The model based on a new 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 ...
