Abstract

Samples of Nassarius reticulatus (L.) were obtained from May to July 2000 on the W Portuguese coast. N, reticulatus imposex (superimposition of male characters onto female prosobranchs) increased with the proximity of harbours. The percentage of imposex-affected females (%I) varied between 0 and 100%. The penis length index (PLI) and the relative penis length index (RPLI) were between 0 and 10.7 mm. and 0.0 and 92.1%, respectively. The vas deferens sequence index (VDSI) ranged from 0 to 5. The average oviduct stage (AOS) varied between 0.0 and 1.3. Sterile females (22 specimens) were found at 8 of the 40 sampling stations with frequencies between 5 and 50% of the total females sampled at each site. Sterility occurred only in females highly affected with imposex. Tributyltin (TBT) and triphenyltin (TPT) female body burden varied from
