By trying to help dolphins, groups like Greenpeace caused one of the worst marine ecological disasters of all time. Few other fisheries are as bad for groups like sharks and sea turtles as the purse seine fishery, and none are as large in scale.
The Cove is a 2009 documentary film documenting the annual killing of more than 2,500 dolphins in a cove at Taiji, Wakayama in Japan. The film was directed by former National Geographic photographer Louis Psihoyos, and was filmed secretly during 2007 using underwater microphones and high-definition cameras disguised as rocks.
Noodling is the practice of catching catfish by letting them latch onto your arm.
To begin, a noodler goes underwater to depths ranging from only a few feet to up to twenty feet, placing his hand inside a discovered catfish hole. If all goes as planned, the catfish will swim forward and latch onto the fisherman's hand, usually as a defensive maneuver in order to try to escape the hole. If the fish is particularly large, the noodler can hook the head around its gills.
This video captures some noodling fishermen in action.
