Overfishing, fishing faster than the fish can grow and breed to maintain sustainable populations, is a big ecological and industrial challenge. The fish we catch are now smaller and fewer than in decades past, key fish populations have been exhausted, and changes like these quickly affect food webs around the globe.
Most coastal fish grow fast and have lots of young. In fact, fish never stop growing, and as a fish grows bigger it has exponentially more young. More older fish in the sea would mean lots and lots more fish in the sea, and ultimately, lots more of the creatures that eat fish, too.
The solution to overfishing is, therefore, simple: We need to stop fishing in many of the places where fish breed and grow big.
