The customised
programme is the first of its kind for Pacific red snapper (Lutjanus peru) and aims to assist
Earth Ocean Farms (EOF) to select for specific traits in the snapper stock that
show higher yields through improved growth and phenotypic traits. The elements
of the selection include insights into feed conversion and product yield.

The in-house genotyping team at CAT
have developed a custom panel of genetic markers to accelerate genetic
improvement in red snapper, analyse performance and ensure the overall health
of the stock.

“It is exciting to apply our
knowledge to new species,” said John Buchanan, president and CEO of CAT,
in a press rlease. “By using a customised approach, our expert team will
be able to quickly show significant improvements for EOF. Ensuring a healthy
genetic diversity among EOF’s broodstock will provide future options as
flexibility and continued improvement are the keys to profitability.”

“The future of sustainably raised red snapper is vitally
important to take the pressure of the overfishing of the wild Pacific and
Atlantic red snappers while meeting the market demand for this delicious fish,”
added Pablo Konietzko, EOF’s director general. “Implementing a
family-based breeding programme is a complex and challenging task, and that is
why we chose to work with the expert team at the Center for Aquaculture
Technologies. The CAT team not only understand fish breeding and genetics, they
also carry practical aquaculture expertise. Their client-oriented approach will
ensure that we will meet our company growth objectives for our mid- and long-term
goals.”

Scientists agree that the potential
of aquaculture production to supply nutritious seafood protein to a growing
world population is greatly enhanced by the rigorous application of genetics
and selective breeding programmes to choose preferred traits and apply these to
breeding and management programmes.
