Pure Algae

Pure Algae creates technologies for regulated land-based seaweed farming that is climate-friendly. They produce the finest seaweed for pharmaceutical, food, and feed firms throughout the year and enable local and organic manufacturing on a worldwide scale. It affects aquaculture to use their vertically built seaweed growth method, which effectively permits nutrient capture while simultaneously increasing production of seaweed, to solve their problem with high nutrient outflows.

Pure Algae is a Danish company specializing in the production of high-quality seaweed, particularly sea lettuce (Ulva spp.), using innovative land-based cultivation technology. Founded in 2018 by Esben Rimi Christiansen, the company has developed a controlled production system that ensures stable, year-round seaweed cultivation free from allergens and heavy metals. Pure Algae's technology utilizes a 40-foot container setup equipped with eight one-thousand-liter tanks, combining saltwater, CO2, nutrients, and LED lights to produce a full batch of seaweed in just one week. This Plug'n'Play solution allows for efficient, weather-independent production and has significant export potential. The company's seaweed is primarily used in dietary supplements, sustainable food innovations, and as an edible accompaniment to seafood. Pure Algae is also involved in the SeaFree project, a collaboration with universities and other companies to develop a closed, sustainable cycle that utilizes residual nutrients and CO2 from land-based shrimp and fish farming to grow high-value seaweed for the food and healthcare industries.

Biokind is a company that produces sustainable protein feed for fish and shrimp farming. The company's innovative product is created through a proprietary natural fermentation process that upcycles non-edible agricultural waste. This approach aims to replace traditional fishmeal and soy protein in aquaculture, particularly in shrimp farms, which are known to be significant carbon dioxide polluters in the sector. By utilizing Biokind's product, the company claims it can potentially reduce carbon dioxide emissions by over 5 billion tonnes. The technology addresses the growing demand for protein in aquaculture, which has seen a 60% increase in production in Europe since 1998, while also tackling the issues of overfishing and deforestation associated with conventional protein sources like fishmeal and soybeans. Biokind's solution aims to make agricultural land use more efficient by valorizing waste products, thus contributing to a more sustainable aquaculture industry.

Ecto is a digital biology company that develops technology to enhance efficiency and sustainability in aquaculture production. The company's primary offering is a digital decision support platform that leverages advanced molecular tools and digital technologies to streamline production and health management in aquaculture operations. Ecto's platform supports deep integrations with over 100 data sources throughout the aquaculture value chain, using multi-generational data to automatically build models for early detection of patterns associated with biological risks. The software covers multiple environmental factors in key phases of production affecting fish welfare and development, including hatchery, well-boat and truck transport, grow-out, and processing phases.
Founded with offices in the US and Norway, Ecto collaborates with farmers worldwide to optimize their operations. The company's solutions have enabled farmers to create 51 million additional healthy servings of protein. In October 2021, Ecto raised USD 7 million in financing led by the Rabo Food and Agri Innovation Fund and Aqua-Spark, with participation from Seventure Partners and existing investors Yield Lab and Vodia Ventures. The funding was intended to advance Ecto's position in the market for digital decision support tools for aquaculture.
Ecto's platform aims to address the challenge of data fragmentation in the aquaculture industry, where much of the data is still locked in paper records, spreadsheets, and disparate software systems. By pioneering structured data capture across the industry, Ecto enables producers to tap into aquaculture industry data to enhance the efficiency and sustainability of production. The company's technology is designed to increase output, reduce environmental degradation, improve animal welfare, and increase transparency and traceability in the supply chain.

Australis Aquaculture is a producer of premium ocean-raised barramundi, operating in Central Vietnam. The company focuses on sustainable aquaculture practices and offers a range of barramundi products under its brand, The Better Fish. Australis utilizes Climate-Smart Ocean Farming techniques in Van Phong Bay, Vietnam, where it nurtures barramundi in pristine tropical waters. The company's barramundi is known for its mild, buttery flavor and is rich in omega-3s, containing half the calories of salmon.
Australis Aquaculture has achieved several certifications for its sustainable practices. It was the first to be certified under the Aquaculture Stewardship Council's Tropical Marine Finfish standard and the first ocean-farmed fish to receive a Monterey Bay Aquarium Seafood Watch Best Choice rating. The company also holds a Best Aquaculture Practices (BAP) 4-star certification.

KnipBio, founded in 2013, is a biotechnology company specializing in the development of single-cell protein technologies for aquaculture, animal feeds, and human applications. The company's core product, KnipBio Meal (KBM), is a high-quality feed protein derived from methanol through industrial fermentation of the microorganism Methylorubrum extorquens. KBM is designed to be a sustainable alternative to traditional protein sources like fishmeal and soybean meal in aquaculture feeds. The product offers a complete amino acid profile along with vitamins, inorganic salts, fats, and carbohydrates, positioning it as a viable partial replacement for fishmeal, soybeans, meat, and skimmed milk powder in various applications.
KnipBio's fermentation process is highly efficient, producing a protein-rich biomass with a high dry cell weight of 120 g/liter and a crude protein content of 67.2%. The company claims its method is a thousand times more efficient than traditional farming practices. KBM has gained regulatory approvals in multiple markets, including FDA GRAS (Generally Recognized As Safe) designation for finfish and shrimp feeds in the US in 2019, and approval from the Canadian Food Inspection Agency (CFIA) for use in salmonid feeds up to 10% of the total diet in June 2022.
In addition to its nutritional benefits, KBM is being explored for its potential to reduce off-flavors in recirculating aquaculture systems (RAS), a common issue in fish farming. The company has been conducting trials with RAS facilities to determine if a diet containing five percent of their single-cell protein product can lower levels of geosmin (GSM) and 2-methylisoborneol (MIB), compounds responsible for off-flavors in farmed fish. Initial results have shown significant reductions in off-flavor in RAS-raised trout.
In July 2024, Larry Feinberg, the CEO and founder of KnipBio, stepped down from his position. Caitlin Wege, who had recently joined the company, was appointed as the new CEO to lead KnipBio's future endeavors.
