Record #210336:

Estimation of natural mortality using catch-at-age and aged mark-recapture data: a multi-cohort simulation study comparing estimation for a model based on the Baranov equations versus a new mortality equation / S.G. Candy.

Title: Estimation of natural mortality using catch-at-age and aged mark-recapture data: a multi-cohort simulation study comparing estimation for a model based on the Baranov equations versus a new mortality equation / S.G. Candy.
Author(s): Candy, S. G.
Date: 2011.
In: CCAMLR Science. (2011.), Vol. 18 (2011)
Abstract: Uses model simulation to test estimation strategy for natural mortality in fish stocks using multiple cohorts and multiple years of catch-at-age and aged mark-recapture data. Develops two alternative estimation models: "fully parametric" Baranov ordinary differential equation (ODE) model; and "semi-parametric" constant catch ODE model which disaggregates fishing and natural mortality differently from Baranov ODE. Model is required to assess natural mortality at Patagonian toothfish fishery in Heard and McDonald Islands.
