Micro-encapsulated hydrolysed fish proteins and ingredients for Larval Nutrition (patented)
The Maripro products were initially created with the aim of providing an alternative form to live feed in rearing of larvae in aquaculture.
The micro-encapsulated, hydrolysed fish protein and oil also have been proven in the rearing of pikeperch larvae and Ray finned fish (S.aurata), Seabass (D.labrax), Arctic Cod (G.morhua), and shrimp species.
The products are available under the trademark MINIPRO and offered at particle sizes ranging from 80 - 500 micron:
Maripro's manufacturing facilities are based in Karmsund, a fishing harbour near Haugesund, Norway. With manufacturing license from the Norwegian Food Safety Authority ("Mattilsynet"), the Minipro series of products is produced using a patent-pending micro-encapsulation technology.
The key raw materials used in the Minipro products are of marine origin that have been carefully selected and quality assured prior to manufacturing. The virtually dust-free microcapsules contain only approved and consistent high-quality feed ingredients. The manufacturing process is physically very gentle, which helps to preserve the more unstable, heat and pressure sensitive nutrients and vitamins within the product.
Each production step is carefully controlled and supervised by specially trained staff according to standard operating procedures to assure consistent physical and nutritional quality. Each batch undergoes vigorous QC testing and analysis in accordance to EU standards prior to being released for sale.
Also available from production in Germany:
