It is among our favourite seafood. But be careful about
eating wild caught mussels.
It attaches itself to a hard surface by producing threads!
is considered a pest outside its natural range.
This edible clam is sometimes very common on our Northern shores,
crowding any hard surface: rocks, pilings, floats. It is well adapted
to waters that are murky and sediment laden.
Features: 5-8cm. The two-part
shell is thin, smooth and usually brownish edged in green. The animal
attaches to hard surfaces with byssus threads, usually in clusters
of many individuals.
uses: Green mussels are considered the economically most
important mussel in our region. They are farmed in many parts of Southeast
Asia as seafood. They grow fast and in dense numbers. Like other filter-feeding
clams, however, mussels may be affected by red
tide and other harmful algal blooms. During such times, the mussels
concentrate toxins and people who eat them may get seriously ill.
Outside its natural range of the Asia-Pacific region, the Green mussel
is considered an introduced pest and an unwelcome invasive species.
There, unchecked by natural predators, the mussels multiply rapidly
and clog industrial pipes, foul aquaculture and disturb local ecosystems.
