Project Description

I provide technical and research support for the following project: ‘Aquaculture of Australian edible sea urchins’: Sea urchin gonad (or roe) is an increasingly desirable food item in various parts of the world and fetches very high prices. As an alternative to harvesting field stocks of urchins, which are now decreasing globally, there is considerable interest in sea urchin production through cultivation (echiniculture). Part of the study examines the effect of temperature on the fertilisation kinetics and larval development of the lamington urchin (Tripneustes gratilla).

My work involves for example husbandry of the urchins in our seawater facility and collecting Kelp (Ecklonia sp.) for feeding them. I also take care of our microalgae cultures – microalgae are an essential food for larval and juvenile aquacultured animals. Popular microalgal species used in their culture include Pavlova sp.and Chaetoceros muelleri. I also process sea urchin gonads for further analysis in the histology unit of our department.
