Trends in world mollusc production
In 2005, worldwide mollusc aquaculture produced 13,468 million tonnes (an increase of 2.34 % compared with 2004) with a value of 11.4 billion dollars.
Mollusc aquaculture is mainly done in Asia but significant production also takes place on other continents, with the exception of Africa.
Production trends for families of mollusc
The most commonly produced family is the Ostreidae (oysters) with more than 4.6 million tonnes. Then come the Vereridae (clams) at 3 million tonnes, the Mytilidae (mussels) and the Pectinidae (scallops). The last family, Solecurtidae, corresponds to a species produced solely in China.

Nine species account for 85 % of worldwide production; Pacific oyster alone represents one third of mollusc aquaculture
