Some deep-sea fish tend to grow more slowly, live longer lives and reproduce only periodically, making their populations easier to deplete. Deep-sea dwelling Orange roughy, like these, can live for more than a century. People began fishing for them in the 1970s near New Zealand. Since then new fisheries have opened up, but catches have plummeted.
