Genomics

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

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.

The microbiome of a parasite can have an impact on how that parasite affects its host – including Atlantic salmon – according to new research.

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 tech…

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.

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…

Martec, the Costa Rican marine finfish producer, has recently announced a new partnership with Xelect to create the first large-scale genetic breeding programme for spotted rose snapper.

After four years, the MedAID project – which looked to improve the genetic performance of Europe’s sea bass and sea bream farming sectors – has drawn to a close, offering hope for advances in Europe’s sea bass and sea br…

The gene editing tool CRISPR is now being used to generate a range of traits in a variety of farmed aquatic species – including salmonids, crustaceans and carp – but there is still a way to go before it is likely to be f…

A gene affecting resistance to a viral disease in Atlantic salmon has been identified using CRISPR gene-editing technology.

A startup that has edited the genes of red sea bream so that they produce a thicker fillet has announced plans to start selling the fish in Japan.

New research into the genome of the kuruma shrimp (Marsupenaeus japonicus) could pave the way for breeding programmes that make it less susceptible to diseases such as white spot.

Aquaconnect, Algal Bio and the Regional Fish Institute have made it onto the prestigious 100 to Watch list, highlighting the companies’ capacity to make a positive impact and bring innovative solutions to the As…

Two of the world's leading aquaculture biotechnology firms have announced plans to jointly deliver genotyping services customised to the needs of individual aquaculture producers.

Newly published research into Atlantic salmon has highlighted a hitherto untapped resource of genetic variation that could help unlock even greater aquaculture production benefits.

Growth hormone transgenic Coho salmon exhibit significantly greater growth rates than selectively bred Coho salmon, in a variety of production conditions and experimental designs, according to emerging research from the …

A breeding programme based on genomic selection has more than doubled the survival rates of rainbow trout that are exposed to bacterial cold water disease (BCWD).

Despite a number of challenges that still need to be overcome, genome sequencing has a growing range of practical applications in aquaculture and, as costs come down, it is going to be increasingly widely used.
