Could ‘blue food’ be the food of the future?

‘Blue food’ is what we call food from the water. The concept of blue food implies that we need to think afresh about how to use resources sustainably - without exceeding ecosystem limits. We also need to take a different approach to what we eat and find alternatives to salmon fillets and fish fingers. Some examples of blue food from the Baltic Sea are algae, round goby and ide fish burgers. At present, just 15 per cent of fish is consumed by humans, but we need to eat the whole fish and completely change the way we use what we catch. Gunilla Rosenqvist, project manager at the Department of Earth Sciences and at Blue Centre on Gotland, explains.
