A report done recently by the UK’s Institute of Mechanical Engineers (IMechE) has discovered that about 1.2-2 billion tons of the food produced in developed countries is either wasted by poor storage, bad distribution, or over rigorous “often perception based” quality standards.
The current wasteful behavior is extremely ignorant, and accounts for 30-50% of the worlds produced food. Spoiling 2 billion tons of food also means that 35% of the world’s fresh water supplies are being wasted. Modern day agriculture uses 2.7 trillion cubic meters of water a year, which amounts to about 70% of all the world’s freshwater use.
The potential to provide 60-100% more food by simply eliminating losses, while simultaneously freeing up land, energy and water resources for other uses, is an opportunity that should not be ignored. Factors affecting waste relate to engineered infrastructure, economic activity, vocational training, knowledge transfer, culture and politics.
Closed containment aquaculture provides us with the ability to reduce food wastage, decrease water requirements and reduce transportation costs to markets.
Controlled intensive aquaculture production systems are poised to expand to an even larger role in the aquaculture production of the Canadian and U.S. domestic edible seafood supply. The most technically advanced closed containment farms utilize Recirculating Aquaculture Systems, termed RAS for short.
