Protein production for aquaculture feed
About 20% of the global animal-based protein consumption is now provided by fish, and 50% of that fish is farmed.
A major advantage of fish farming, a strong basis for food sustainability, is the very high Feed Conversion Ratio (FCR).
Salmon are cold blooded and naturally buoyant (i.e., less energy required for heating and swimming), which is why they have an excellent FCR – it takes as little as 1Lb of dry feed and 1.2Lbs on average to grow 1Lb of salmon. When compared to other livestock, the potential sustainability advantages are obvious. However, it typically takes 3Lbs of wild-fish that are generally not used for human consumption to produce fishmeal for 1Lb of dry feed and thus 1Lb of salmon. Demand for fishmeal is increasing significantly, thus prices are escalating and quantities are declining. Alternative, sustainable and economic sources for high-quality protein replacements to fishmeal are needed.
White Dog Labs offers a sustainable solution by producing Single Cell Protein (SCP), with similar protein and amino acid content as fishmeal. The solution combines MixoFerm high yield, with its FlexFeedstock capability (e.g., by-products from ethanol plants), and a low-cost plant that is co-located with existing infrastructure such as dry-grind ethanol plants.
A summary of the MixoFerm solution’s advantages include:
- Consumption of low cost and sustainable feedstocks, e.g., ethanol by-products
- High cell mass on ATP yield – opens up opportunities for anaerobic fermentation
- Opportunities to co-locate SCP production with ethanol plants, providing additional cost reduction
Moreover, White Dog Labs’ microorganism development capabilities allow for:
- Higher value SCP with an improved amino acid content
- Enhanced nutritional value such as included vitamins and organic salts
- Continual product improvement and differentiation
