Fish farming counts many different ways of producing according to the species and type of production, like salmons, trout, tilapia, and many more. The demand in fish is growing and fish farming needs sustainable solutions to overcome its everyday challenges, such as improving the animals’ feeding, their natural defences, water quality, and also the animals’ well-being during the whole production.

Salmonids are among the highest-value species in aquaculture and most notorious farmed aquatic animals for consumers. With a long production cycle (1 to 2.5 years), specific physiological needs and complex systems (freshwater and marine farming), salmonid production faces an important number of challenges to be dealt efficiently with, like acute stress during transportation or risks related to bacteria and parasites around the world.

Trout are one of the first farmed aquatic species and freshwater trout farming has expended itself around the globe in every continent. Trout as carnivorous animals are facing demand of sustainable and cost-effective feeding.
