First published in International Aquafeed, March-April 2016  


Formulating aquaculture feeds may be a very exciting process, but it is equally challenging and demanding. There are a great number of parameters that have to be taken into consideration and an even greater number of restrictions that have to be managed.

Feed quality is mainly driven by three factors; knowledge of nutritional requirements of each target species, the manufacturing processes employed and finally; the raw ingredients used.

The quality and dietary composition of the raw ingredients are influenced by the nutritional value, type, quality, inclusion levels, price, regulatery limitations; among others. The feed quality and cost is a key consideration when selecting the raw ingredients based on actual nutrient contents and monitoring their variation; not only their price and nutrient profile.

The nutrient variation in raw ingredients will ultimately result in increased variation of nutrients in the final feed. The factors contributing to that mainly include genetics, environmental conditions and current season.
