    Abstract

    The predatory gastropod Cymarium cingularum was found to occur in large numbers in the pearl oyster farm at Krusadai from February to July. 1986. They feed mainly on spat end young oysters below the size 40 mm in OVM and thereby causing large scale mortalities of pearl oyster stock. This menace was eradicated by periodical checking and hand picking manually. In all 50,901 oysters were found dead in the 4,010 cages inspected and 934 Predators were collected and destroyed. The gastropods ranged between 21 and 88 mm In length.
