Cryopreservation – involving the freezing and ultra-low temperature storage of ova and sperm – has been demonstrated with varying degrees of success across a range of farmed aquatic species, but more standardised techniques are needed to ensure that it works c…

Although the $4 billion giant river prawn (Macrobrachium ronsebergii) sector has largely stagnated over the last decade, new breeding programmes could help pave the way for its resurgence.

A new paper argues that there’s an urgent need to improve understanding of the genetic mechanisms involved in host resistance to whitespot syndrome virus (WSSV) and sea lice – two of the greatest health challenges facing shrimp and salmon farming respectively.…

Dr Melony Sellars, CEO and managing director of Genics Pty Ltd, recently developed four new real-time PCR assays that can help detect the presence of decapod iridescent virus (DIV1) in shrimp.

Scientific techniques developed for the human health industry can hugely improve the performance of aquafeeds, according to Timothy Bouley.

Triploidy is widely used in aquaculture to improve growth rates, reduce possible impacts of farmed animals on wild aquatic ecosystems and enhance product quality, but there’s room for improvement and for alternative technologies.

Genomic selection is an effective means of improving aquatic animal health, with recent studies suggesting it can be used for a range of conditions including whitespot resistance in shrimp, herpesvirus resistance in Pacific oysters and Vibrio resistance in sol…
