Zusammenfassung: This paper describes a method and a FORTRAN program for the estimation of von Bertalanffy growth parameters, total mortality rates and gear selection/recruitment parameters from a time series of length-frequency samples weighted by catch per effort (e.g., numbers caught per hour by length class each quarter of the year). The length frequencies are separated into normally distributed components each of which represents a cohort. This method is constructed to allow for continuous, seasonally variable recruitment all year-round and is intended to be used especially for tropical and other fish stocks displaying an appropriate recruitment pattern.
