Rethinking aquaculture to boost resource and production efficiency

Sustainable and efficient aquaculture solutions

The world’s oceans, lakes and rivers are no longer an unlimited source of human food because many of the world’s fish stocks have been fished to their limits or are on the verge of collapse. This encourages the aquaculture sector to grow, but if aquaculture farms are poorly located or poorly managed they have the potential for significant negative impacts on the environment. An ever-increasing demand for fish thus calls for more sustainable and more efficient solutions.

State-of-the-art recirculation systems

Farmers compete with other sectors for access to resources and space, whether at sea or on land. These factors can be important barriers against establishing or expanding conventional aquaculture farms. Looking into land-based recirculation systems, the advantage is that they use less than 500 litres of water per kilo of fish produced compared to the land-based flow-through systems, in which water intake is typically around 50,000 litres per kilo of fish produced. Other important benefits include the 24/7 monitoring and control that ensure consistently good water quality and feeding programmes tailored to the particular needs of individual species. These optimised conditions boost growth, minimise the risk of disease and mortality, and reduce medication to a minimum.

This white paper offers insights into methods and best practice examples of resource efficient sea and land-based aquaculture solutions for farming high quality seafood.
