Abstract

The histological gonadal cycle of Tegula aureotincta was determined at Bahia Asuncion Baja California Sur. Monthly samples of 25 to 30 organisms were collected from January to December 2006. They were processed by histological technique, embedded in paraffin, sections 7- ?m thick were stained with hematoxylin-eosin. The sex ratio was 1:1. Both sexes presented gametogenesis and maturity stages the year through. Two major spawning events were identified in autumn-winter and spring. The maturity and spawning times have close relations with the seasonal change of sea water temperature.
