Lewy, P. (1986). Integrated stochastic virtual population analysis. Estimates and their precision of fishing mortalities and stock sizes for the North Sea whiting stock. COPENHAGEN, DENMARK: ICES.
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.

Misra, R. K. (1986). Fitting and comparing several growth curves of the generalized von Bertalanffy type (Vol. 43).
Zusammenfassung: The earlier version of the von Bertalanffy growth formula (VBGF) has three parameters and is a special case of the “generalized” VBGF which has four parameters. The special VBGF can easily lead to erroneous results whereas the large flexibility built into the generalized VBGF enables it to provide a biologically realistic fit to the data. The author presents a statistical method and a computer program in Fortran to fit the generalized VBGF to a sample (a sample comprises several age groups, with one or more observations in an age group) and to examine statistically the fit to a sample and to compare statistically these curves (and their individual parameters) fitted to several samples. An example is provided, which also compares the fit of the generalized VBGF with the special VBGF.
