Operation Dolphins

Really the big fight is taking place in Taiji in a small bay.  They kill any thing that swims close to the shore line.  They use nets to catch and herd them into the bay.  Once there they proceed to kill the animals.  You may ask yourself how they do this.  Well this is how:

They go out in small boats to known dolphin migratory routes. Positioning their boats strategically, they space out to form a line and wait for the dolphins. When the dolphins arrive, the fishermen drop long metal pipes into the water, and by banging on the pipes they create a wall of sound. The sound interferes with the dolphins' ability to navigate - it disorients and panics them. The dolphins swim away from the sound, and the fisherman maneuver their boats herding them into a small shallow bay. Once in the bay, nets are drawn across the mouth of the bay to keep them penned in.  The fishermen usually injure a few of the captive dolphins with a spear thrust or a knife slash - dolphins will not abandon these wounded family members.  Trapped in the shallow water, the dolphins mill about trying to stay as far from land as possible until the next morning. In the morning, the fishermen draw the nets in, forcing the dolphins closer to shore where they kill them by stabbing and slashing them with knives and hooks. The dolphins thrash about for as long as six minutes each as they slowly bleed to death, turning the sea literally red with their blood.

There is a documentary about this.  It's called "The Cove".  It is a must see.
