This is a fascinating story. The Chilean Sea Bass, known originally as the Patagonian Toothfish, was unknown till the late 70s. Even then, it was used mainly as a filler in fish fingers and the like. Suddenly, the gourmet industry discivered the fish and reckless overfishing has pretty much led to the extinction of the fish in LESS THAN 40 years.
Guess there are some perils to being popular...LOL.
BTW, Wall St. Journal had an excellent article a few months ago on the high stakes game being played over the remaining toothfish/sea bass stocks by various countries.
And then there’s the story of how 1 chef, and 1 recipe, almost wiped out another species - redfish.
