Project will allow Hendrix Genetics to select individual trout with improved metabolic rate, which predicts feed conversion.

In a press release, the multi-species breeding company Hendrix Genetics writes that it initiated a new study with US start-up GenetiRate, which has developed a technology that can predict feed conversion based on metabolic rates measured on fish larvae or muscle tissue.

The project is set to start soon, with a review of the results scheduled to occur at the end of 2020. The study will use the technology to study Troutlodge breeding stock has the potential to make significant genetic progress for our customers and the industry

The ability to select trout with significantly improved feed conversion would mean increased profitability for farmers. Producers gain the benefit of increased growth rate while maintaining feed intake.

GenetiRate was founded by Dr. Benjamin Renquist from the University of Arizona and recently won the Seafood Innovation Award at the North Atlantic Seafood Forum. GenetiRate has run successful trials using its technology with other aquatic species. If successful, the project will allow Hendrix Genetics to select individual trout with improved metabolic rate, which predicts feed conversion.

“We are excited to begin these trials to understand how our selection process can be applied to improve both growth and feed efficiency in rainbow trout. We appreciate that Hendrix Genetics recognizes the value in applying our technology to better serve their customers’ needs. By improving feed efficiency, GenetiRate and Hendrix Genetics Aquaculture aim to help the aquaculture industry meet the sustainability demands of the consumer at the restaurant or grocery store,” says GenetiRate Founder and President Benjamin Renquist.

Director of R&D Hendrix Genetics Aquaculture Robbert Blonk stated: “Feed conversion is notoriously difficult to measure on an individual level in aquaculture species. However, this new technology allows us to measure individual feed conversion and thus improve efficiency of the Troutlodge breeding stock. Ultimately, this translates into an improved final product with increased profitability and sustainability for the entire industry.”
