Abstract
Panulirus penicillatus and Panulirus longipes bispinosus are the main species of spiny lobsters caught by commercial fishermen in the New Caledonian lagoon. The growth of the males and females of these two species is described by a Von Bertalanffy curve based on observing growth in captivity and in the field, and according to the statistical analysis of cephalothoracic length-frequency histograms obtained from commercial catches. A minimum suitable catch size has been calculated from the study of the males of P. penicillatus, which have the most rapid growth. For practical reasons, due to the artisanal frame of this fishery, this limit size (Cephalothorax Lengthlim = 7.5 cm) is recommended for both species and both sexes.
