Xelect has launched a one-stop genetic broodstock health check for trout producers, bringing the benefits of genetics in aquaculture to even small companies.
The GeneXpertise service provides advice on genetic best practice, a detailed report on the genetic health of a customer’s population along with guidance on which crosses to make and which to avoid.
“Xelect’s experts can help you develop your genetics roadmap and set you on course for the years to come,” said Xelect chief executive, Prof Ian Johnston. “For example, we can check the genetic health and selection suitability of your broodstock population, or we can provide direct recommendations for your next stripping season,” he added.
Trout are highly fertile and a single female can produce thousands of juveniles. This rapidly leads to ‘inbreeding depression’ – a loss of genetic variation resulting in increased deformity, reduced vigour and poor survival. Once that happens there’s no way back, without purchasing new broodstock animals from a different source.
The service is not a replacement for Xelect’s full breeding programme but can give producers access to experts at a scale that suits them. “It’s also really quick – just a few weeks from start to finish,” said director of operations, Dr Tom Ashton.
The company has also a developed a free online 2 Minute Broodstock Genetic Health Check to help business owners know what they should look out for.
