While the climate crisis gathers front-page attention on a regular basis, people - even those who profess great environmental consciousness - continue to eat fish as if it were a sustainable practice.

An animal that is very abundant, before it gets extinct, it becomes rare. So you don't lose abundant animals. You always lose rare animals. Therefore, they're not perceived as a big loss.

People don't know the past, even though we live in literate societies, because they don't trust the sources of the past.

I personally like the idea of shellfish aquaculture. These are animals that stay quiet, they stay where you put them, and they clean up the water.

Tilapia have often been represented as the aquatic chicken, and it's perfectly justified.

If we don't manage this resource, we will be left with a diet of jellyfish and plankton stew.

We suggest that in the next decades fisheries management will have to emphasize the rebuilding of fish populations embedded within functional food webs, within large 'no-take' marine protected areas.

In the Java Sea in Indonesia, I have seen fishers going out in the morning, six of them going out and coming back with five pounds of fish. That is the end point, a pound of fish per person per day to sell for rice. That's where fisheries go if you let it happen. That's where it stabilizes. These people cannot feed their families.
