The whales, which tin value 135,000 pounds (61,235 kilos) person been a absorption of conservationists for generations. Recently, efforts to prevention the whales person resulted successful caller restrictions connected U.S. lobster fishing, and pushback from the sportfishing manufacture astir those caller rules.
