of spat takes place during November-December and March-April. Of the several cultch materials tried,
oyster shell, used automobile tyres, rigid PVC, lime-coated tiles and asbestos were found to be suitable.

panels. Tliespjt grew initially at the rate of 2-3 cm per month. Spat transferaed to suspmded wire bag
grew faster than the feral ones. The oysters attained^ 7.0 cm shell-height in about 7 months. The size
at fiiBt maturity was 12-14 mm for males and 24-26 mm for females^ Study of 4he condition and edibility
