Water Quality Update – October 16, 2015

Not all stations were sampled this week but those that were sow no problems this week.


High levels of Karenia brevis (red tide) were reported along shore and offshore of Bay and Gulf counties (Panama City and Port St. Joe). Moderate levels were reported for Manatee, Sarasota, and low values were recorded from Charlotte and Lee counties.


The FWC fish kill database is still down and so we are not aware of any fish kills in the area at this time


UWF surveyed for lionfish inshore this week but did not find any.


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