Genetics

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.

Shrimp producers are going to have to embrace new technologies and production techniques if they are going survive, according to Rabobank’s senior seafood analyst Gorjan Nikolik.

Wider application of genetic improvement in aquaculture, with a focus on selective breeding, will help boost seafood production without the need to hugely increase the volume of inputs – including feed, land and water – required by the sector.

The Aquaculture Innovation Showcase is coming in September. Ahead of the event in London, The Fish Site spoke to TransAlgae’s VP of research and development, Ofra Chen, to discuss how algae can revolutionise the health and nutrition of farmed fish.

A project which aims to selectively breed feed-efficient lines of tilapia in order to improve the economic viability of aquaculture in areas where feed is expensive and scarce has recently been launched.

Southeast Asia's largest, yet long-troubled shrimp farming firm, PT Dipasena Citra Darmaja, has been given a much-needed boost as the Asset Management Company (PPA) managed to seal a US$240 million commitment to help finance the firm's revitalization.
