New approaches to aquaculture can boost resource and production efficiency with minimal impact on the environment.
Overfishing and environmental impact of aquaculture
For more than four decades, global demand for fish has increased at almost twice the rate of the growth in population. Today, half of all fish consumed come from aquaculture, thereby easing some of the stress on wild fish stocks. However, poorly managed aquaculture production can have significantly negative impact on the environment.
Technologies for resource efficient fish farming
Meeting the fish’s biotic requirements is key when running an aquaculture production system. When fish are farmed intensively in captivity, growth conditions quickly deteriorate if the right measures are not taken in time. Knowhow and smart monitoring and control systems are therefore of major importance. Other relevant equipment include reliable pumps for feed dosing, valves and shut-off equipment, UV systems to disinfect the recirculated water etc.
Strict environmental legislation encouraged Danish innovation
Since the late 1980s, Danish companies and research institutions have specialised in resource efficient aquaculture solutions for farming high quality seafood. The key to their success lies in their full control of the water environment. This is especially the case for land-based recirculation systems where the water intake is down to just 1% per kilo of fish compared to the traditional flow-through systems.
