Feeds for marine, freshwater and brackish water

Aquaculture pellet feeds are plant- and animal-based feeds intended for fish on farms. They contain the macro nutrients, trace elements and vitamins farmed fish need to stay healthy, and are formulated with specialized ingredients to ensure proper digestion and optimum health.

Aquaculture fish feeds are produced in pellet form for specific habitat conditions (marine, freshwater, brackish water). Through high extrusion technology they can be produced as floating, sinking and slow-sinking feeds. Cold and hot extrusion techniques allow the feeds to be produced to the required quality standards.
