Securing the nutritional requirements of cultured fish, the technical quality of the feed optimal for the production system as well as defining right feeding strategies are key challenges that both fish farmers and aquafeed producers should face to ensure a sustainable production.

Key reasons to attend this course

Better understand the importance of the use of new ingredients and new formulations.
Acknowledge the main challenges in feed production.
Better use feeds, feeders and fish feeding monitoring.
Recognize the impact of customers’ preferences and the legal framework in feed production.
Design feeding trials to better adapt feeds and feeding to the farm conditions and production systems.
Network with professionals to exchange experiences on feed formulation and new feeding management technologies.
