Description Not Available
The e¡ect of temperature on the development,
growth, survival and settlement of Perna viridis was
studied under controlled conditions to provide information
needed for the development of commercial
hatchery technology for green mussel P. viridis. Total
mortality of the larvae occurred after 24 h at temperatures
of 33 1C and 35 1C. At 24 1C, larvae took
longer to settle than at temperatures of 27 1C, 29 1C
and 31 1C. For optimum larval development (8^13 h),
growth (17.270.84 mmday^1) and survival (55.27
0.84%), a hatchery rearing temperature of 31 1C is
required. For settlement no signi¢cant di¡erence
was seen between the percentage settlement at
29 1C (49.373.34%) and 31 1C (45.871.76%). However,
the process of settlement began and ended earlier
at 29 1C (from15 to18 days) thanat 31 1C (from18
to 20 days). Thus for larval settlement a temperature
of 29 1C is recommended.
