Resumen:
Munida subrugosa was sampled monthly from November 1997 to November 1999 in the Beagle Channel by
means of an epibenthic trawl. The reproductive cycle started in May, re｣ected by the occurrence of
ovigerous females. Maximum size of oocytes, maximum value of gonadosomatic index in females
(16.8 gmmcarapace length [CL]71) and males (1.6 gmmCL71), and the proportion (70%) of ovigerous
females with full egg-clutches occurred in June. Since the proportion of ovigerous females in October was

females with full egg-clutches occurred in June. Since the proportion of ovigerous females in October was
5% and the planktonic larvae reportedly hatch in September, the embryonic development lasted 90^
120 days. Females and males attained physiological maturity at 9.9 and 8.0mmCL respectively, and males
reached morphometric maturity at 24.4mmCL. Fecundity was correlated with female size (r¼0.85) and
was between 124 and 10,750 eggs per female. Average diameter of recently extruded eggs was 0.69mm
