The two letter-writers perhaps don't appreciate the benefits of raising fish for food.
Putting aside the obvious health and conservation benefits of cultured fish, freshwater and marine fish are coldblooded, so unlike land animals, they don't require energy to heat their core. Also, water provides neutral buoyancy so they don't fight against gravity. Both of these key energy-saving facts mean fish are one of the most efficient converters of feed to edible meat at a ratio of about 1: 1. This is important as we search to find efficient ways to feed more than seven billion of us.
I agree with the writers that farmed fish must be fed a sustainable diet and encourage them to learn more about how B.C. fish farmers are leading the way in using sustainable ingredients.
The benefit of raising fish for human consumption is not a new revelation, as ocean conservationist Jacques Cousteau wisely stated decades ago: "We must plant the sea and herd its animals using the sea as farmers instead of hunters."
