Zusammenfassung: Integrated Stochastic Virtual Population Analysis (ISVPA) is a method by which fishing mortality and stock size are estimated using standard statistical techniques. The estimation procedure has been programmed in FORTRAN 77 for a VAX 11/750. The dataset for North Sea Whiting (Merlangius merlangus ) presented to the North Sea Roundfish Assessment Working Group have been used to illustrate the ISVPA method.
