Some population parameters of commercially-important fishes in the Philippines

The estimates of the von Bertalanffy Growth Function (VBGF) parameters and mortality parameters (Z and M) for some of the commercially-important species caught in the Philippine waters are presented using the FAO-ICLARM Stock Assessment Tools (FiSAT) software. The data collected from various major fishing grounds in the Philippines were utilized in the analysis. Whenever possible, the ELEFAN I method, Shepherd's method, Powell-Wetherall's Plot, Modal Progression Analysis (MPA), Length-converted catch curve, as well as, the method to estimate the maximum possible length, were utilized to compute for the population parameters.
