UH OH! THE FISH ARE DYING BECAUSE OF OVERFISHING
In the book by Mark Kurlansky called World Without Fish It says that, "Beware of new types of fish that are suddenly being seen everywhere. That was the case of the orange roughy. It was also the case with the redfish
In "Sustainable Fishing Methods" it says that trolling is "Another method of hooking fish individually, but rather than each line being handheld as it is in hook-and-line fishing, trolling involves towing individual anchored lines from a moving boat. It's still sustainable because by-catch is minimal and can be quickly released.
ACCORDING TO "HOW TO BUY FRESH, SUSTAINABLE SEAFOOD" THEY SAY TO WATCH OUT FOR CHEAP FISH BECAUSE THEY ARE PROBABLY CAUGHT IN SUSTAINABLE WAYS.
Mark Kurlansky says in World Without Fish "An Eco-label is a "seal of approval" awarded to fisheries and aquaculture operations deemed sustainable and responsible by third-party certification bodies."
