Have your fish, and eat it too
After hearing years of depressing news about our enormously depleted fish populations, and how many of our solution-oriented fish farms are each actually more polluting than the combined “raw human sewage from a town of several thousand people,” I was about to put my last can of tuna in the closet as a proof for my grandkids of the days when we had fish. But now, with much improved technology and the concerned investment of a few business-minded individuals, your goldfish may have something more to smile about tomorrow.
Welcome to Recirculating Aquaculture Systems, or RAS, and the future of your salmon dinner. RAS systems are closed-loop, meaning they recycle over 99% of the water, produce natural fertilizers for local farms, allow for both fresh and saltwater varieties, and release miniscule to no pollution. Plus, their performance requires so little water they offer a world of commercial possibilities in places with limited water resources.
And, although it may seem challenging to compete with the many off-shore fish farmers with free water and low-start up costs, RAS systems have proven to be incredibly marketable with their healthy fish (anti-biotic and hormone free) and “green” production methods. With sales doubling each year, you may soon be seeing RAS raised fish in your local store and finally feel a more hope that you can have your fish, and eat it too.
