Abstract

The ovarian development and the size at sexual maturity of Panulirus infatus (Bouvier) of the Mexican Pacific and Gulf of California coastal waters were determined monthly between August 2001 and July 2002, using 191 females with carapace lengths (CLs) ranging from 44.94 to 94.18 mm. The seasonal cycle of ovarian development was divided into seven stages. The diameter of mature oocytes differed depending on ovarian maturity stage (inactive = 44-115 μm, developing = 115-192 μm, ripe = 285-438 μm, re-developing = 85-158 μm, re-ripe = 133-183 μm, spawned = 29-87 μm, and recovering = 33-58 μm). Size of the smallest mature female was 53.02 mm CL, and the size at which 50% of females reached sexual maturity was estimated as 63.73 mm CL. Mature females were present every month, indicating a continuous reproductive pattern, although gonadosomatic index values were highest between February and July, with the maximum value in June. Results from this study indicate that the present minimum legal size, based on other spiny lobster species, is too large for P. infatus. © The Royal Society of New Zealand 2009.
