Scientists say there are a few ways we can do this. First commercial fishing companies need to catch fewer fish. This will increase the number of large predatory fish. Another way to improve the biodiversity of the oceans is to develop aquaculture-fish farming. Growing fish on farms mean we can rely less on wide caught fish. This gives species the opportunity to restore themselves. In addition, we can make good choices about what we eat. For example, we can stop eating the fish that are the most in danger. If we are careful today, we can still look forward to a future with fish.
