orange roughy

For centuries, orange roughy went mostly unnoticed by humans. These fish thrived in the dark, the cold, and the intense pressure of the deep sea. When fishing boats started reaching new depths in the 1970s, orange roughy were fished almost to extinction. Today, orange roughy are protected by fishing limits. But it will take decades for their populations to recover.
