Penchaszadeh Biología TBT imposex Volutidae marine pollution Odontocymbiola magellanica (Gmelin, 1791) is a volutid snail from Patagonian shallow waters. Sampling byscuba diving in depths of 6-10 m was performed in Golfo Nuevo, Golfo San José and Golfo San Matías, Patagonia,in order to study the imposex occurrence. O. magellanica showed between 85% and 100% imposex near harborswith high marine traffic in Puerto Madryn, Golfo Nuevo, and a Relative Penis Size Index (RPSI) between 0.77 and3.84; in scuba diving zones with sport boats traffic the imposex percentage decreased between 35% and 59% and theRPSI was between 0 and 0.15; in zones with low marine traffic the percentage of imposex was null. Although thespecies is under imposex occurrence in the area we observed females spawning in 2002. A posterior study in 2004near the harbor zone showed the persistence of imposex in these marine gastropods. In Golfo San José the imposexwas null and in San Antonio Este, Golfo San Matías the imposex was 100 % and the RPSI 0.12. Imposex occurrencesuggests the presence of TBT in the areas near harbors. 2005 artículo científico 0037-8607 https://www.redalyc.org/articulo.oa?id=52408802 en http://www.redalyc.org/revista.oa?id=524 Comunicaciones de la Sociedad Malacológica del Uruguay application/pdf Sociedad Malacológica del Uruguay Comunicaciones de la Sociedad Malacológica del Uruguay (Uruguay) Num.88 Vol.9 |
