Fishmeal replacement strategies: Just a question of protein?

Martin Guerin, Adisseo Asia Pacific PL, Singapore

In the early years of aquaculture, fishmeal was the ingredient of choice of aquafeed formulators. It was seen mostly as an excellent protein source with the right amino acid profile and the added benefit of fish lipids, which made it a nutrient dense raw material. Due to its higher cost compared to plant proteins, efforts were already made early on to substitute fishmeal with other protein sources.

However it is in the last 20 years that the question of sustainability of the supply of fishmeal has taken a driving seat in reducing fish meal levels in aquafeeds. As levels of fishmeal decreased in formulations and as nutritional knowledge improved, fishmeal was no longer seen as mainly a source of protein and fat, but also of other important nutrients that plant proteins are unable to supply.

Today’s fish nutritionists need to find alternative sources of methionine, EPA/DHA, cholesterol, phospholipids, minerals, feed appetence factors, immunity factors, when they substitute fishmeal with other raw materials. In addition, plant proteins and animal by-products proteins come with their own set of nutritional issues such as impaired gut health, reduced digestibility, NSPs, phytic acid, altered kinetics of feed intake and digestion, or mycotoxins for plant materials, saturated fats for animal by-products, and most often lower nutrient density. This presentation will review how these nutritional issues impact feed performance and what strategies are available to overcome them.
