Genetics

Access to a growing array of recent and emerging technologies offers hope for breeding shrimp which are either faster growing or more resistant to specific diseases, but the performance of improved lines in pond production may often fall short of expectations.…

Gene-editing tools such as CRISPR have huge potential to improve the sustainability and profitability of the aquaculture industry, according to James Sibley – an undergrad with ambitions to be a star of the sector.

The environmental impacts of aquaculture are often in the spotlight. The need for sustainable practices is now firmly embedded in the minds of the public, governments and industry – but this sometimes presents trade-offs in fish welfare.

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.…

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…

The latest in a series of webinars organised by the team behind the F3 Challenge, which is focusing on algae and seed oils in aquafeeds, will be live streaming on The Fish Site on 20 May.
