Thousands of Fish Dead in Nevada Marina Mystery
Scientists can only theorize what caused the drop in oxygen levels that caused a massive fish kill in the man-made lake.

An estimated 100,000 trout, bass and catfish have died over the past month in the Sparks Marina, Nevada. The man-made lake was created nearly 15 years ago and stocked fishery has flourished since then.

Scientists say a bitter cold snap could have caused oxygen-poor waters to rise from the old rock quarry's bottom to the surface, but they don't understand what sparked the massive die-off and they have been unable to detect any live fish in the 77-acre lake.

The former aggregate pit operated by Helms Construction Co. had been found to be contaminated in 1988 by pollutants leaking from an adjacent tank farm, but state environmental officials said all the pollution had been cleaned up.

Broward Canal Yields the Largest Invasive Snakehead Fish - A 14-pound, three-ounce bullseye snakehead, a member of an exotic family of aggressive, fast-growing, razor-toothed air-gulper fish was pulled from the Margate canal recently. The snakehead is an Asian invader and while the fish hasn’t proven much of a monster in Northwest Broward, where it was first discovered in a lake in 2000 and has been corralled by the canal systems’ flood-control gates and water structures, the capture does show that the population is quite healthy in South Florida.
