Maintaining or optimizing feed efficiency with plant-based ingredients

Optimized formulation: fewer ingredients of aquatic origin, equivalent performance

Limiting the use of ingredients of aquatic origin and reducing the Fish-in:Fish-out (FI:FO) ratio

Aquaculture production has increased significantly over the past few decades and this growth is expected to continue to meet the rising demand for animal protein. The need to preserve aquatic resources and improve the sustainability of animal feed has led to the gradual replacement of fish meal and fish oil with other, more sustainable raw materials, often of plant and microbial origin. By-products from the grain and oilseed industries form a significant portion of these alternatives

Mitigating the effects of plant proteins to ensure performance in aquaculture

Due to the presence of antinutritional factors and contaminants, high levels of plant-based protein sources in aquafeeds can lead to reduced growth performance and feed efficiency in fish, as well as changes in gut microbiota composition and immune response. These factors can have a negative impact on the profitability of fish production. Consequently, identifying sustainable solutions to mitigate these effects and ensure fish performance is a major priority.

Increasing flexibility and innovation in formulations to balance performance, health, and the environment

Raw materials and additives with specific properties are becoming increasingly important in helping the industry address a number of challenges. Additives have demonstrated their potential to help the aquaculture industry develop new formulations that maintain fish performance and health while reducing environmental impact. Plant-based products are among the inputs reported in the literature as having positive effects on fish performance, thanks to direct or indirect benefits such as improved feed efficiency or enhanced resilience of the animals to health challenges.
