| Description |
Boring organisms, particularly polychaetes and sponges cause considerable damage to the pearl oyster Pinctada fucata reared in the farm. The most serious pests are the polychaete Polydora ciliata and the boring sponge Cliona vastiflca. The incidence of attacks by the boring organisms on oysters from the pearl culture farm at Veppalodai and Tuticorin harbour and from the natural beds have been studied and the oysters from Veppalodai were found to be the most affected. Of the several methods tried to control boring organisms, immersion of the oysters in fresh water was found to be most effective in controlling the polychaetes. Brushing the external surface of the shells with 1 % formalin was found to be effective in controlling the boring sponge.
