Intensive use of extractive fishing is threatening important species and forces governments to impose temporary stoppages whilst the profitability of fishing fleets is decreasing and ship-owners are seeing their livelihoods threatened.
In this context and given the continuously growing demand for fish due to the exponentially growing population, breeding of different types of fish, crustaceans and molluscs in fish farms appears to be the only solution.
Fish larvae feed on multicellular microorganisms -Rotifera and Artemia-, which in turn require a balanced and natural feeding on microalgae. This is the only way to achieve healthy farmed fish which compare favourably with those found in the wild. Microalgae are therefore a basic need in the aquaculture sector.
