As Cambodians celebrated Independence Day on Monday, Nov. 9, fishermen near Phnom Penh made a very special catch befitting the occasion: a rare Mekong Giant Catfish, also known as the “royal fish” because of its enormous size.

Zeb Hogan is not your average angler. He travels the world searching for underwater giants. Perhaps you have even seen him on Monster Fish which airs on Nat Geo Wild. But when he is not on the water, he calls Northern Nevada home.

Hundreds of fish have turned up dead in an urban Nevada lake, a year after a die-off claimed all of its estimated 100,000 fish.

After losing the entire fish population in the Sparks Marina, tests show the water there has no toxins and the oxygen level is rising again.
