Salmon rendered sterile through gene editing are exhibiting encouraging behaviour and performance during the grow-out phase, according to new research results.

Ways to commercialise the production of finfish rendered sterile by novel methods sparked a thought-provoking discussion at the end of the inaugural International Finfish Sterility Workshop, which was held in Stirling this week.

In the second part of the feature, Professor Ross Houston, who is currently involved in using gene editing to improve resistance to diseases in salmon, explains the barriers – technical, regulatory and ethical – that need to be overcome before such techniques …

Despite being overfished in China and South East Asia, a suite of advances in sustainable aquaculture of a number of grouper species is bringing benefits to producers and consumers alike.

Dr Laura Braden, an eminent sea lice researcher who now works for AquaBounty, lives on Prince Edward Island, Canada, with her husband-to-be, a young baby, two German shepherds and a Norwegian forest cat. Here, she explains how genetic engineering can help save…

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.

The benefits that salmon farmers obtain by sourcing their stocks from cutting-edge breeding programmes are chronically undervalued, according to a new study.

As the search for the best way to produce sterile farmed fish stocks continues, novel methods such as germ-cell migration disruption could offer good alternatives to inducing triploidy, according to one US researcher.
