By 2050, the global population is expected to reach 9.7 billion, posing a tremendous challenge on adequate nutrition and food security and safety for all inhabitants.
Fish has become a most important source of nutrition and is increasingly supplied by aquaculture. The success and breeding quality in cage farming is highly influenced by the rearing conditions. So how does robotic net cleaning contribute to fresh clean water, the production of tonnes of healthy fish, and an easy operation?
Growth of aquaculture needed in order to keep up with increasing global fish consumption
Fisheries and aquaculture remain vital sources of food, nutrition, income and livelihoods for hundreds of millions of people around the world. According to the UN Food and Agriculture Organisation (FAO), 50 percent of fish production will be from aquaculture in 2021, which makes aquaculture the fastest growing food sector right now. An indispensable factor for the quality and success of bred fish species as opposed to wild caught fish is the condition of the cage nets used in captive breeding.
Nets submerged in seawater easily acquire a coating of algae, molluscs, fish food, fish secretions, and other biofoulings. The results of fouling can be disastrous for the production of fish.
First of all, there is an increasing risk of disease or even death of fish because fresh seawater and oxygen cannot flow freely in and out of the nets. Fouled nets are also more prone to damage and tearing, causing fish to escape and expensive repairs to the nets.
Furthermore, due to biofouling the nets become heavy, causing an extra load to the service vessel and its anchoring system.
