Description:

"ASAP (A Stock Assessment Program) is an age structure stock assessment modeling program originally developed by Chris Legault and Victor Restrepo while they were at the Southeast Fisheries Science Center (Legault and Restrepo 1998). Modifications made in subsequent iterations are described at the top of Appendix 1. ASAP is a variant of statistical catch-at-age models. This latest version can integrate annual catches and associated age compositions (by fleet), abundance indices and associated age compositions, annual maturity, fecundity, weight, and natural mortality at age, and annual environmental covariate effects on stock-recruit parameters or natural mortality (when estimated). It also can incorporate (size-based) calibration estimates that relate abundance index time series with periodic changes in gear. However, it is also flexible enough to handle data poor stocks without age data (dynamic pool models) or with only new and post-recruit age or size groups. Further information and instructions for new features and options are described in the ASAP version 4 User's Guide provided with the installation"--Introduction.
