Live Food Enrichment
Marine fish contain large amounts of Fatty Acids (DHA, EPA and ARA) in their phospholipids. As those Fatty Acids cannot biosynthesize, they are considered to be absolutely essential (EFA). Although rotifers and artemia are often used as live feed for marine fish larvae, they are considered poor in EFA. Therefore the live food enrichment diets are crucial as they provide farmed fish with a necessary amount of fatty acids.
Rotifer Feed / Green Water
Green water is a common technology in aquaculture with many benefits. Adding algae in the water during larvae culture is a direct food source stimulating immune system of larvae. Algae are known to be a key ingredient for rotifer production, which can be an expensive process requiring human resources and appropriate infrastructure. In fact typically algal production can cost over 5% of total fry production! This is why using algae products can significantly reduce costs and simplify your production process.
Artemia Substitute
Vitellus, a unique Artemia-based feed, ideal for weaning (transition from live food to formulated feed) which can also be used during shrimp PL transport
Larval Diet
Live feed at the early larval stages is necessary because larvae’s digestive system is still in development. The beginning of weaning will depend on the digestive capacities of the larvae and the rearing conditions. Artificial diets are the best solution to go to a complete regime based on quality nutritional formulations and progressively switch from live feeds. Thanks to some recent advances in fish feeding regimes, hatcheries can grow their fish on larval diets achieving the best results.
Nursery Diet
Preparing fish for the growth phase is one of the most important steps in aquaculture. Indeed, after weaning, fish fry need well balanced growth and hatcheries – cost effective feeds. BernAqua’s highly performant nursery diet provides fish with highly nutritional, easy-to-digest energy intake.

Broodstock
Our Broodstock diet offers a good nutritional balance as it is specifically formulated to meet the known dietary needs of fish at this stage.
Waterconditioning
Aquatic organisms need optimal water conditions as they minimize the risk of deficiencies and ensure the healthy growth of shrimp increasing their survival rate. The bacterial control is therefore a key to avoid some pathogens and toxic agents, which can harm the production performance.
