Study finds sustainable alternative protein source for shrimp, salmon

For the first time, a single cell protein could replace a key ingredient in aquaculture feeds.

Results from a recent study showed potential to lower aquaculture feed costs and provide a new sustainable alternative protein source.

A study showed results for the first time that a single-cell protein could replace a key ingredient in aquaculture feeds for fish and shrimp.

The study looked at KnipBio Meal as a food for white shrimp, Atlantic salmon, and smallmouth grunts.

"All three species experienced similar or better growth and survival rates when fed a diet containing KnipBio Meal when compared to fish given a diet of conventional commercial feed," said KnipBio. "In blind taste tests, panelists rated the shrimp raised on the KnipBio Meal mixtures as statistically similar to control shrimp."

Researchers at Massachusetts-based biotechnology company KnipBio collaborated with the New England Aquarium, the University of Massachusetts at Boston, Roger Williams University and the USDA Agriculture Research Service.

“In addition to creating healthier fish, there are other inherent benefits to using KnipBio Meal as a replacement for agricultural protein in fish feed," said KnipBio CEO Larry Feinberg. "An estimated 100-acre KnipBio facility can match the protein production of a 10,000-acre soy operation, dramatically reducing the environmental footprint for production.

"The process also eliminates the need for fertilizers and pesticides and reduces energy use.”
