Balance amino acid intake in fish and shellfish diets

The metabolism of aquatic animals requires a high intake in protein and essential amino acids.

It is important to consider amino acids individually when formulating feeds for aquaculture. This method helps meet the need for these essential nutrients.
Thanks to the formulation of aquaculture feeds balanced in amino acids, we can reduce the necessary quantity of dietary proteins. Fish and shellfish feeding thus increases in efficiency.
Substituting fishmeal in feed is a crucial objective for improving aquaculture sustainability.

Support the development of fishmeal substitutes

Substituting fishmeals in animal nutrition is a fundamental objectivefor improving the sustainability of the aquaculture sector. The goal is to produce feeds that are more respectful of the environment but  equally  high  performing.

Fishmeal substitutes include alternative ingredients like vegetal proteins or other innovative sources such as unicellular organisms (bacteria, yeast, etc.) or insect proteins. These must ensure a sufficient content in amino acids in order to guarantee the nutritional quality of the feed for fish (such as salmon) and shellfish. A correct supplement in feed-use amino acids makes it possible to effectively adapt the aquaculture’s species diet and alleviate the need for fishmeal.

Reduce ammonia-rich excretions in aquaculture

Performance of fish farms, animal welfare, environment: in terms of these issues, aquaculture ponds releasing lower ammonia levels come out as winners.

Fish excrete nitrogen in the form of ammonia. When animals live together in high densities in the ponds, the concentration of ammonia threatens their balance as well as that of the environment. And yet, a fish diet balanced in amino acids and supplemented in feed-use amino acids allows to reduce the protein-based supply and therefore decreases nitrogen-rich excretion.

Mitigate salmon cataracts

Cataracts widely affect salmon, decreasing their welfare and its ability to feed itself correctly.

Amino acids play a beneficial role in the ocular health of salmon. A balanced intake, specifically, in Histidine, a precursor of N-acetyl-Histidine (NAH), guarantees protection of the ocular lens and an antioxidant action that participates in decreasing cataracts.
