Feed giant Skretting is collaborating with another feed alternative ingredient supplier -- Silicon Valley-based startup NovoNutrients -- as it fast tracks its search for sustainable solutions to major nutrition challenges in the aquaculture industry.

NovoNutrients Protein, rebranded from "Novomeal," makes protein-rich aquatic and animal feed ingredients from waste carbon dioxide, hydrogen and single-cell bacteria.

Skretting will test NovoNutrients' product at its aquaculture research center in Norway, with the aim of reaching a procurement contract between the two firms.
