Abstract
The growth parameters W∞ and K of the von Bertalanffy growth equation were estimated from size-frequency data of the sea hare Dolabella auricularia using an objective, computer-based method. The results obtained from two locations in the central Philippines were comparable, although based on only a few individuals; the means for both sites were W∞=493 g and K=0.9 (yearly basis). A value of Z=3.66, corresponding to an annual survival rate of 2.6%, was estimated for the juveniles and adults from a length-converted catch curve. Spawning and recruitment were found to occur throughout the year with peaks in May to July and September to October.
