The Asian green mussel
Perna viridis
Linnaeus (1758) was spawned in hatchery and the larvae were
successfully reared to setting. The larvae grew through the straight hinge, umbo, eyespot and pediveliger
stages in the pelagic phase before metamorphosing into the plantigrade stage and setting as spat on a
suitable substratum.
Isochrysis galbana
was used as a standard algal food until settlement of spat after
which a mixed algal diet of
I. galbana
and
Chaetoceros calcitrans
was provided. Spat fall began on 21st day
and continued up to the 35th day on a variety of substrates. The shell length
