From this story on 11alive.com:
The classic line when someone says they've caught a big fish is "pics or it didn't happen." Well this one did happen. A 1,360 pound sturgeon was caught by fishermen in China's Heilongjiang River this week. The type of sturgeon, known as a Kaluga, or is sometimes called a river beluga, and is claimed to be the largest freshwater fish in the world.
