Shellfish Breeding and Hatchery Management (2+1)

10.2.6 Spawning

The eggs are yellow in colour at the time of spawning and turn to grey or brownish grey or black before they hatch and release the larvae in 14 days.

The eggs will measure from 280 to 380 micro meter in diameter, while the early and late zoea larvae measure at 1.0 and 1.4 mm in length, respectively. A berried female measuring 140mm will relase 2 million larvae. The size of berried females from the wild ranged from 93-175 mm (400-1000g) and that of ablated females will be 135-140 mm (340-700g).
