Summary of Project

Giant Grouper (Epinephelus lanceolatus) and Purple Grouper (Epinephelus cyanopodus) are both highlyvaluable emerging aquaculture species, and these industries have a strong desire to implement selective breeding programs. To do so, breeding companies need greater control over breeding processes to ensure consistent and reliable production. Cryopreservation offers the potential to facilitate 1:1 crosses at different time intervals and enables the production of larval batches without relying on spawning broodstock. This project aims to undertake the first step towards this objective, by developing a speciesspecific solution for dilution and handling of grouper milt, and to extend the viability of grouper milt during short-term storage. This project will characterise the biochemical characteristics of each species milt and utilise advanced sperm analysis and cellular assays to optimise components of the diluent solution.
