Promotes a healthy gut

Whether yoghurt or miso, fermented foods are recognized worldwide for their ability to keep human stomachs healthy – and livestock are no different. Whether fish, pigs, or pets, FeedKind protein has been proven to help promote and maintain a healthy gut and all the benefits that brings, from better nutrient absorption to improved feed conversion and growth rates.

We have seen improvements in growth rates across several species including Atlantic salmon, rainbow trout, and weaning piglets.

Sustainable protein to meet global demand


FeedKind is a safe, nutritious, traceable and price competitive protein that has been commercially validated through extensive trials.

Our patented production process uses no agricultural land and very little water. Completely additive to the food chain, it helps us meet the world’s growing demand for food without placing extra stress on our planet’s resources.

FeedKind can be a sustainable substitute for other proteins such as fishmeal and soy protein concentrate, which are currently the primary sources of protein used in commercial aquaculture and livestock farming.

One commercial scale FeedKind protein plant, if used to replace soy products for fish feed, would free up enough land to feed as many as 250,000 people. The land area represented is equal to an area the size of Chicago, Illinois.


Calysta offers the shrimp aquaculture industry a new level of transparency by introducing a sustainable protein allowing users to determine whether a shrimp was fed FeedKind with a simple test. When combined with leading certification standards, producers, retailers and consumers can be guaranteed that their food is free from the taint of modern slavery.

More widely, this provides additional piece of mind for consumers, retailers and manufacturers over the source, safety and sustainability of their food. We are already
closely collaborating with a number of the world’s most influential companies to bring FeedKind’s built-in traceability to the aquaculture and livestock supply chains, bring greater transparency to ensure products are ethical, sustainable and produced to the best standards possible.

Increases Growth Rate

Rigorous studies done at Akvaforsk and Aquaculture Protein Centre, Norway showed that growth rates of Atlantic salmon increased when fishmeal was replaced by FeedKind Aqua protein. Despite a lower apparent digestibility coefficient of crude protein, the fish retained significantly more nitrogen at increased levels of FeedKind protein, which drove improvements in feed efficiency and feed conversion ratios.

Fully Customizable

Pelleted or powdered, extra amino acids or lower fat content, Calysta can work with clients to create customized products to fit their needs. FeedKind protein can be modified with Calysta’s industry leading biotechnology and custom tailored for individual species or applications.
