Industrial Production of Microagglomerated and Microencapsulated diets

 

Acuinuga is developing microdiets for the nutrition of fish, molluscs and crustaceans larvae, uniquely formulated and primarily incorporating local ingredients in their composition.

The aim is to decrease the need for phytoplancton and zooplankton in the production of aquaseed, due to their high production costs and difficult handling.  The partial substitution of live diets for cheaper, readily available microdiets allows for the year-round production of seed, avoiding the typical heterogeneity in particle size and composition of live diets.

These state-of-the-art microdiets make possible the design of species and- developmental stage-specific feeding strategies.

Several factors must be taken into account when producing microdiets:

Preliminary trials conducted to date indicate a substitution potential of up to 80% of live feed, and a subsequent 60% reduction in production costs depending on species, developmental stage and production systems.
