Abstract

In order to study the distribution and abundance of Strombus gigas (Linné 1758) larvae were collected every month from January to December 2005 in twelve sites of Quintana Roo. Plankton tows were made with a conical net of 500 ?m mesh-size. During the sample period, 417 veliger were identify. Larvae were more abundant during August, with 179 larvae (42.9%) and they were lest abundant in April, with 16 larvae (3.83 %). Small larvae (200 to 320 ?m) were more abundant in August. Analysis of Correspondence GLM was different significantly between months (p = 0.005388). High abundance of small sizes of larvae suggests that Quintana Roo North area could be a possible site of production of Strombus gigas larvae. It could be related to presence of a adult stock at Puerto Morelos, in the Quintana Roo North area in Yucatan Peninsula of Mexico
