The use of fishmeal in fish feed diets is considered unsustainable for the long-term development of aquaculture and there are increasing pressures on the industry to find substitutes. Consequently, fishmeal has been largely and successfully taken out from the diets of several omnivorous farmed species using substitutes from plant proteins and processed animal proteins (PAPs).

However, this approach has proven more difficult to implement across carnivorous species without affecting their growth performances and welfare. Fishmeal in aquafeed diets remains an important source of essential amino acids on which carnivorous species are particularly dependent for their growth. On the other hand, plant proteins are also known to be sources of anti-nutritional factors that cause adverse physiological effects on fish gut and metabolism, increasing the risk of chronic or acute health disturbances.

In this context, single-cell proteins, such as yeasts, have long been identified as desirable functional ingredients to support fishmeal replacement strategies in aquaculture diets and counteract the negative effects of plant-based protein sources on carnivorous farmed species.

At Towards Sustainable Aquafeed conference, organized on September 7 at VICTAM Asia and Health & Nutrition Asia in Bangkok, Otavio S. Castro, global species manager aquaculture at Phileo by Lesaffre®, will present the latest advances within the company to maintain feed efficiency, growth and health of carnivorous fish and shrimp in low fishmeal diets using Prosaf®, Phileo’s highly purified and functional yeast extract.

Eleven presentations will focus on recent developments for aquafeed producers and practical steps for more sustainable and profitable aquafeed and aquaculture production.
