Really? We used to buy it at fish markets in Kaohsiung all the time.
Yup. They started dropping nets lower and lower, and suddenly found this huge cache of Orange Roughy off New Zealand, around 3km down. But, as it turns out, the Roughy lives in such a cold and dark environment, they hardly reproduce. You can't find one now, because 90% of them were wiped out. They won't recover for centuries.
Just another example of what we do before we know what the costs will be.
