US aquaculture’s first forays into gene-edited catfish have produced fish that appear to be more resistance to disease – but the tech could face a long road before achieving regulatory approval.

The diatom Phaeodactylum tricornutum already enjoys use in China’s aquaculture sector but faces contamination threats from zooplankton – but researchers have identified a novel gene that could allow the algae to…

Researchers are exploring fish and shellfish responses to health and environmental pressures with an eye to create stronger breeding programmes and sustainable animal protein.

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…

The US Food and Drug Administration (FDA) is putting AquaBounty’s AquAdvantage salmon through an additional environmental assessment (EA) following a lawsuit from multiple organisations that resulted in a court order cal…

Gold River Productions, a segment of Trans American Aquaculture, will supply shrimp post larvae (PLs) to the universities to support their research efforts in sustainable food production and aquaculture nutrition.

Benchmark is searching for six new scientists to bolster its global genetics department.

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 techniq…

Scientists from Nofima has created a new method for assessing the immune status of salmon smolt, giving researchers and farmers a better idea of how the fish will adapt to seawater.

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…

Maryland’s Hoopers Island Oyster Co has launched its Restoration Division and completed its initial projects for the Watermen’s Associations in tributaries along the Chesapeake Bay.

Genome mining techniques have helped to explain how sea cucumbers produce defensive chemicals that enable them to fend off foes in the murky depths.

Whether cod farming can be profitable, despite the high production costs, is the subject of a new study by Norwegian researchers.

Researchers from James Cook University have mapped the complete genome for Australian tiger prawns, potentially unlocking disease resistance and productivity gains for the aquaculture sector.

A new £1.7 million research effort from Scotland's Roslin Institute and the University of Stirling's Institute of Aquaculture hopes to identify genetic mechanisms that could make Atlantic salmon more resistant to sea lic…

Genetic selection could hold the key to improving feed conversion ratios (FCRs) by allowing salmon farmers to select fish that grow well with fewer feed inputs.

Professor Ross Houston, who currently leads the aquaculture genetics team at The Roslin Institute, University of Edinburgh, will join Benchmark Genetics (BG) as the Director of Innovation on 1 March 2022.

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 Paci…

Researchers with Nofima are hoping to establish a method that can make fish more robust and tolerant to various stresses.
