Abstract

A field survey was carried out to assess the availability of Lambis species in by-catches of four fish landing centres (Tuticorin, Velapatti, Vembar and Ramanathapuram) in Gulf of Mannar coasts. At each centre, by-catch trash from 10 fishing vessels were screened for 15 days randomly between April and May 2012. Five species of Lambis namely L. lambis, L. chiragra, L. crocata, L. scorpius and L. truncate were recorded from the by-catches. Among the species, L. crocata was more commonly observed shells in by-catch survey and high number of Lambis species turnover was recorded in Vellaptti landing centre. The results indicate that indiscriminate collections of prohibited species are still underway in the Gulf of Mannar coasts.
