INVE launches Natura diet range for early-stage marine fish larvae

Tuesday, December 31, 2019

INVE Aquaculture has launched ‘Natura’, a new diet range for early-stage marine fish larvae. The new formulation has been developed to simplify the weaning process and provides key nutritional components for the initial stages of larval development.

The Natura diets are available in 4 different sizes used from co-feeding to post-weaning. Natura is a floating, slowly sinking feed formulated to obtain satisfactory feed acquisition and feed uptake.

“Feed digestibility is of great importance, especially at the initial stages of larval development when the digestive tract is under development,” stated Alessandro Moretti, Product Manager Fish Hatcheries. “Larvae fed with Natura show superior acceptance of formulated feed.” 

The Natura diet range has been developed using carefully selected protein sources for the early stages of the fish larvae. Not only proteins of sustainable marine origin are used, but also adequate protein sources in hydrolyzed form to obtain the most optimal uptake of amino acids and peptides in the initial stages of larval development. This together with high quality n-3 HUFA inclusion promotes larval development, juvenile growth, survival and quality. 

For optimal ease of use, Natura diets can be fed daily over multiple rations according to the larval age, fish density and water temperature. They are ideally supplemented with enriched rotifers and/or Artemia.
