Tarpon’s return has silver (king) lining
"There was a lot of time when it was at medium levels, which could cause fish kills," said red tide tracker Earnest Truby, a research scientist at the Florida Marine Research Institute in St. Petersburg.
Truby also noted high levels, which definitely cause fish kills, in mid-March and from late April through early May, during the peak of tarpon migration.
Red tide: Test results show upswing in red tide levels
"The situation in Lee County is not good," said Earnest Truby, a scientist in FMRI's aquatic health unit.
Red tide is the common name for a bloom of microscopic algae that emits a toxin that causes respiratory irritation in humans and can kill fish, even at low levels.Health officials warned people with emphysema or asthma to avoid the beach.
Dead goliath grouper, trout, redfish and catfish washed ashore at the Sanibel Causeway, and goliath grouper and other smaller species washed ashore at Fort Myers Beach this week, FMRI reports show.
In Collier County, the red tide has scattered dead fish on beaches from Wiggins Pass to Marco Island, a county red tide report issued Friday says.

Earnest Truby, a research scientist with the Florida Fish and Wildlife Conservation Commission, said scientists cannot predict how long it will last.But Truby said people should monitor the red tide reports on the Internet and also the weather reports, particularly for the wind direction, if they want to avoid the side-effects.

When the wind is blowing toward shore, low levels of Karenia Brevis can cause eye, nose and throat irritation in humans, said Earnest Truby, research scientist at Fish and Wildlife Research Institute.Larger concentrations kill fish and marine mammals such as dolphins and manatees.Truby
said this year's bloom was first discovered in a sample taken June 15.He
said FWRI scientists cruised their research vessel along the Southwest Florida coast to take more samples last week.
The concentrations of Karenia Brevis in last week's samples were about half of what they were in the June 15 sample.
"I guess that could be encouraging," he
said."There weren't any fish kills or anything like that."Truby
could not guess whether conditions were ripe for the algae to flourish or die off.

Water samples taken June 22 showed what scientists call background concentrations (less than 1,000 cells per liter), but samples taken Thursday near the Sanibel Causeway showed medium concentrations (100,000 to 1 million cells), said Ernest Truby, a research scientist at the Florida Marine Research Institute.
"That would account for the fish kills," Truby
"It seems to be increasing from last week," Truby
