3. 01.1 QUÈ ÉS?
“Disease is the biggest risk to the
industry. It undermines financing
and market development and yet
the industry is chronically under
invested in disease management.”

Functional feedsFunctional feeds are regarded as the future of
the aquaculture:
- by embracing nutrition strategies to address
specific stresses, environmental situations, life
stage requirements and pathologies, the industry
can optimize animal performance as well as
operational efficiency;
- by preventive health management through feed,
aquatic animals can divert more energy to tissue
growth and reduce biological energy reserves
needed to fight disease.

5. Functional feeds:Functional feeds:
- provide benefits other than just nutritional,
- support health and reduce the risk of disease.
