How many of us have been told at some point in our lives “don’t worry…there’s plenty more fish in the sea”?
This old proverb might comfort us for disappointment in love, but taken in its most literal sense, few people seem to believe it.
There is something circular about the idea of catching fish to use as feed for farmed fish, livestock, poultry and our pets. And with about one third of the global fish catch going in this direction, most of it destined for aquaculture, you might well ask whether growing the farmed fish to put in your supermarket has deprived a hungry or malnourished person of food.
It might surprise you to learn that fish are more similar to fruit and vegetables than they are to poultry, cattle, or any of the other animals we eat. At least, they are if you think about the variety of shapes and sizes that fish and fruits and vegetables come in. As foods though, the more important similarity is that these various types differ widely in the nutrition they offer. So as with fruit and vegetables, while admonitions to eat more fish are often heard, exactly what kind of fish you eat matters – especially if you are malnourished.
