We know it's already back to 70 degrees, but remember a few days ago, when everyone was shivering? Whenever there's a chance of a freeze, we get the same stories about farmers in the central and northern parts of the state picking fruit rapidly and spraying their oranges and strawberries. (So that the water freezes around the fruit, protecting it.) But we rarely hear about what goes on underwater. According to this story in the Key West Citizen, a number of fish died during the cold snap when water temperatures plummeted:
A brief but steep drop in water temperature last week is blamed for killing scores of fish, including barracuda, snook and goliath grouper.
Everglades National Park rangers and backcountry fishermen who braved a cold front that blew through South Florida last Wednesday and Thursday reported multiple fish kills from the shallows of Florida Bay to as far south as Boca Grande.
Early Thursday morning, water temperature in Florida Bay just north of Long Key had dipped to 58 degrees, down 20 degrees from a recorded high of 78 degrees at 2 p.m. on New Years' Day.
Air temperatures hit a recorded low of 36 degrees at John Pennekamp Coral Reef State Park last Thursday morning.
58 degrees. Wow. We never would have thought that a few days of cold could cause a 20-degree drop in temperature so quickly. That's unbelievable. And that is
cold. We've swum in 58-degree water, and we could barely feel our fingers and toes after the 30-minute race. (Or during the race for that matter -- our arms and legs were on autopilot at that point.) So, point is, we feel for those poor, poor fish.
Of course, a fish's misfortune is a cause for celebration in the pelican camps:
As with much of nature, death to one species may mean extended life for another.
"The white pelicans have been pigging out on the dead fish," Christi Showler, an interpretive Everglades park ranger at the Flamingo Visitor Center, said Friday.
"I just conducted a canoe trip into Noble Hammock, a little north of Hell's Bay, and there are dozens of little fish floating on the surface," she said. "The white pelicans are having a field day on the floating fish. They're to the point where they are too full to eat."
Expect to see some very fat pelicans in the coming weeks.
