Trochus: status, hatchery practice & nutrition

Trochus shell is highly sought after for buttons and costume jewellery. Australia, Indonesia and the Pacific Islands supply about 7000 tonnes of shell annually, and there is concern about depletion of the fishery. These proceedings arose from a workshop that took place at the end of a project that involved the Northern Territory University and universities in Eastern Indonesia, which studied prospects for culture of trochus for reseeding depleted reefs. The project's success led to funding of a second phase project by ACIAR.
