A bunch of old tires. Maybe not to fish. Let's get our hooks into the controversy surrounding artificial reefs on today's EnvironMinute. Fishermen have been sinking junk into the ocean for a very long time in order to attract fish. And it works.
Many fish seem to like the artificial high-rises as well as their natural, flatter homes.
But the question is whether more housing means more fish, and not just a redistribution of fish. The answer seems to be that it depends on the species of fish and on the area. But the answer is simpler for those species that are already overfished. For them, there's already plenty of housing. Having more won't help them.
