"Remember that the "499,400 pounds wasted" mainly consists of sublegal halibut. These fish have run the natural gauntlet and won...only to get hammered in a trawl.
"They have made it through the most vulnerable stages of development. They are no longer subject to the high natural predation once they have reached ping pong paddle size and they would have likely made it to legal size if not for the trawlers.
"So...that 499,400 pounds represents a helluva lot more pounds and value if left trawl free. Makes the wasted value even more disgusting."
Keep yer flippers wet.
