The grern mussel, Perna vjridis spawns throughout the year at Ennore near Madras. This assures continuous availability of mussel seed at frequent intervals almost throughout the year. The, length at first maturity 1s 16 mm (age: about 16 months). Experiments conducted to understand the spattall pattern at Ennore reveal that, on average, 112 spat/month settle in an area of 56.25cm2 of granite stone collector. The maximum settlement of 869 spat/month has been recorded during June. The effects of biotic and abiotic factors on settlement pattern of spat are discussed.
