Put salmon farms in land-based fish tanks. This is an online demand we see quite often in the comments sections of SeaWestNews Facebook page.

Sustainability is the key to all food farming, whether it is fish in the ocean, or fruits, vegetables, grains and cattle/poultry on land.
All types of farming should be focussed on sustainability/water conservation, which includes avoidance of the depletion of natural resources in order to maintain an ecological balance.
Meanwhile, farmers must supply food for a rapidly growing global population without depleting our limited fresh water resources.
Yet, as we monitor the comments on SeaWestNews articles, there seems to be one recurring demand, “Raise them on land.” This is the sole solution from our local “environmentalists” who insist they want to see salmon raised in land-based tanks – regardless of the 4.16 billion litres of fresh water these tanks would need.
It is not news that the world is running out of fresh water. We know that 70% of the earth’s surface is covered by water. We know that only 2.5 percent of that (70%) is fresh water, and we know that only 1 percent of that (2.5%) is easily accessible.
“Even then, just 1 percent of our freshwater is easily accessible, with much of it trapped in glaciers and snowfields. In essence, only 0.007 percent of the planet’s water is available to fuel and feed its 6.8 billion people.” – National Geographic.
