There are three types of scallop found in the D'Entrecasteaux
Channel.
|
- Pecten fumatus - Commercial Scallop
- (Edgar, 1997)
|
- Habitat: Sand; 0 - 80 m depth
- Distribution: WA to Central Qld, including Tasmania
- Maximum Size: Length to 145 mm
- Diet: Plankton (Filter feeders)
- Comments:
- The uppermost valve is flat with a curved shell
usually buried under the sand. Larval scallops float in the plankton
for up to 6 weeks, then settling on hard substrate. They don't move
to soft sediments until they reach approximately 6 mm in length. The
largest animals are up to 15 years old. This has traditionally been
the main species targeted commercially. The population of commercial
scallops in the D'Entrecasteaux was devastated and is only just
recovering.
