Water Quality Update – September 18, 2015

As we move into autumn the number of rainfall events is declining – and so are the advisories. The salinities in some locations have significantly increased but things look good.


FWC reported background levels of red tide near Gulf County in the panhandle, Sarasota and Manatee counties in SW FL this week but no Karenia brevis was not detected anywhere else in the state.

UWF team did not survey for inshore lionfish this week but we have another confirmed sighting of one near Ft. McRee. UWF will be surveying this area for others soon.

The FWC Fish Kill Database is still down.

There has been concern about cases of Vibrio infection. We have posted an article about this bacteria which you can find at http://escambia.ifas.ufl.edu/blog/2015/07/10/what-you-need-to-know-about-vibrio-bacteria-in-gulf-waters/


Health Advisories – 3 reported this month

Fish Kills – none to report this month

Red Tide – none to report this month

Inshore Lionfish – 1 was found near Ft. McRee and Sherman Cove in Big Lagoon


Here are the numbers…
