Imposex, Organoestañosos, Tributilestaño, S. chocolataAbstract
El imposex es la imposición de caracteres sexuales masculinos sobre el sistema reproductivo femenino de caracoles gasterópodos prosobranquios. Este fenómeno se ha asociado a compuestos organoestañosos empleados como
agentes biocidas en las pinturas antiincrustantes aplicadas sobre muelles, embarcaciones e instalaciones de cultivo,
principalmente con el tributilestaño (TBT). El presente trabajo pretende evaluar la ocurrencia de imposex en los caracoles
marinos Stramonita chocolata que habitan en la playa La Mina de la isla San Gallán (Ica, Perú). El porcentaje de imposex
fue del 33,3 %. El índice de la longitud relativa del pene (RPLI) fue de 36,23. La relación entre la longitud de la conchilla y
la longitud del pene en machos y en hembras no fue estadísticamente significativa.
