And as the distance and depth of fishing have expanded,so has the variety of species we target.For example, the Patagonian toothfish neither sounds nor looks very appetizing.And fishermen ignored it until the late 1970s.Then it was rebranded and marketed to chefs in the U.S. as Chilean sea bass,despite the animal actually being a type of cod.Soon it was popping up in markets all over the world and is now a delicacy.Unfortunately, these deep water fish don't reproduce until they're at least ten years old,making them extremely vulnerable to overfishing when the young are caught before they've had the chance to spawn.
