Those fish are absolutley massive! I wanna go so bad, that would be so much fun but yea I agree that the fish weren't landed very nicely in some cases, like the one on the rocks..... If that keeps up those fish they are advertising wont be in very good shape in a few years.
Patagonia is already in rough shape. Off the east coast is the richest fishery left on earth. Massive commercial fishing happens there. When you look at SA at night from space, the brightest lights are all the commercial squidders and other operations running around the clock.
I am under the impression that getting to 'Jurassic Lake' is quite the ordeal 7 - 10 hours from anywhere and its really tough on anyone without a helicopter. Its one of those rich guy destinations and they are the minority on planet earth. Aside from that , that lake is close to 18km by 18km and they are only fishing from a few select spots from shore showing that the lake is chocked full of beasts. Enough to last a few trips anyway. If I had to choose an exotic location to travel and fish , Patagonia is by far one of the most interesting places to go to on earth and that lake is probably only one of many.
I feel what Loop is doing out there is not that bad compared to bow fishing carp from speedboats or pulling fish out of a lake with your truck.
