Broodstock collecting off Groote Eylandt

Published

Researchers from the Department of Primary Industry and Resources Northern Territory (NT) Fisheries Division and rangers from the Anindilyakwa Land Council (ALC) spent last week collecting mature Blacklip Rock Oysters from the waters off Groote Eylandt.

Thirty nine mature Blacklip Rock Oysters were flown back to the Darwin Aquaculture Centre (DAC) where they will be used as broodstock. Breeding began on Friday, and will see the larvae progressing through the hatchery over the next three weeks. The DAC team aims to produce 100,000 spat (juvenile oysters) to send back to Groote Eylandt. Research into the growth and survival of tropical rock oysters (TRO) includes ongoing collection of data by NT Fisheries and the ALC rangers to establish the best systems and locations for farming oysters.

The TRO project is funded by the Cooperative Research Centre for Developing Northern Australia (CRCNA) and involves research teams in the NT and Western Australia seeking to reform technical and regulatory processes to support and grow oyster farming in Northern Australia.

The project also seeks to support hatcheries to condition and spawn broodstock year-round, build increased oyster production, growth and survival and to increase capacity within Aboriginal communities to participate in the sustainable growth of commercial aquaculture businesses.

For more information on the TRO project go to the CRCNA website.
