Abstract
To determine the distribution and abundance of S. gigas veligers, duplicate plankton samples were collected bimonthly from August 1997 to July of 1998 in six sites at Chinchorro Baok. Plankton tows were realized with a conical net 0.5 m diameter and 202 µm mesh opening. 58.52% of veligers were found in rainy season, 35.46% in cold season and only 6.02% were collected in dry season. Higher abundance occurred at stations Penelope. Centro Key and Centro West Key. 89.08% of veligers corresponded to stage I, 3.76% lo stage II, 0.25% to stage III, 6.52% to stage IV, and only 0.38% were competent, and suggest that Chinchorro Baok is an important source of veligers. Larval density varied from 0.00093 veligers/10 m3 at Lobos key in May to 7.42 veligers/10 m3 at Penelope in Augusl Larvae abundance was related with juvenile "zero-phase" abundance in the bottom.
