How Does Utah Keep Its Mountain Lakes Stocked With Fish? By Blasting Them from a Plane

If you visit Utah's mountains and see fish raining from the sky, don't be alarmed: The aerial fish dumps are how the Utah Division of Wildlife Resources keeps its lakes stocked with trout. You can watch the process, called "extreme fish stocking," in the video below.

The Utah DWR posted this clip to its Twitter account on Tuesday, August 21. In it, water is shown streaming from the bottom of an aircraft, and many flailing fish along with it. The drop from the plane to the lake surface below is roughly 150 feet.

Dropping a load of fish from such a height might seem inhumane, but the animals actually have an impressive survival rate. The Utah DWC writes on Twitter that between 95 and 99 percent of the fish involved in the restocking effort survive the journey to the lake. The trout are only one to three inches long, which means their terminal velocity isn't great enough to cause any real damage when they hit the water's surface. Though it looks traumatic, dumping the fish from the air is actually less stressful, and less deadly, for them than transporting them on the ground.

Aerial fish dumping is a common practice for states with high mountain lakes where hikers like to fish. Most high-elevation lakes in Utah stay below 65 degrees through the summer—a trout's ideal temperature for feeding.

Denver's Temperature Dropped a Record 64 Degrees In 24 Hours

One sure sign summer is over: On Wednesday, residents of Denver, Colorado were experiencing a comfortable 82-degree day. Just before midnight, the temperature dropped to 29 degrees. Between Wednesday and Thursday afternoon, the Denver airport recorded a differential of 79 degrees down to 24 degrees. At one point on Wednesday, a staggering 45-degree drop was seen in the span of just three hours.

All told, a one-day span saw a 64-degree change in temperature, from a high of 83 to a low of 19, a record for the state in the month of October and just two degrees shy of matching Denver’s all-time record drop of 66 degrees on January 25, 1872. On that date, the temperature plummeted from 46 degrees to -20 degrees.

Back to 2019: Citizens tried their best to cope with the jarring transition in their environment, to mixed success. On Wednesday, the city’s Washington Park was full of joggers and shorts-wearing outdoor enthusiasts. Thursday, only the most devoted runners were out, bundled up against the frigid weather.

The cold snap also brought with it some freezing drizzle which prompted several vehicular accidents, including 200 reported during Thursday's morning commute. It’s expected to warm up some in the coming days, but residents shouldn't get too comfortable: Melting ice could lead to potholes.

Invasive Snakehead Fish That Can Breathe on Land Is Roaming Georgia

A fish recently found in Georgia has wildlife officials stirred up. In fact, they’re advising anyone who sees a northern snakehead to kill it on sight.

That death sentence might sound extreme, but there’s good reason for it. The northern snakehead, which can survive for brief periods on land and breathe air, is an invasive species in North America. With one specimen found in a privately owned pond in Gwinnett County, the state wants to take swift action to make certain the fish, which is native to East Asia, doesn’t continue to spread. Non-native species can upset local ecosystems by competing with native species for food and habitat.

The Georgia Department of Natural Resources’ Wildlife Resources Division is advising people who encounter the snakehead—a long, splotchy-brown fish that can reach 3 feet in length—to kill it and freeze it, then report the catch to the agency's fisheries office.

Wildlife authorities believe snakeheads wind up in non-native areas as a result of the aquarium trade or food industry. A snakehead was recently caught in southwestern Pennsylvania. The species has been spotted in 14 states.
