SARASOTA, Fla. -- Over the past three days, nine dead dolphins have been recovered from waters off Sarasota County.

The animals had been found dead amid a 9-month-long red tide outbreak that's killed thousands of marine life in Gulf waters off Southwest Florida in recent weeks.

From Aug. 7 through Aug. 9, Mote Marine Laboratory's Investigations program recovered the nine dolphins with the help of Venice Marine Patrol officers, Venice Police, Florida Fish and Wildlife Conservation Commission, West Coast Inland Navigation District personnel, Clearwater Marine Aquarium and the Sarasota Dolphin Research Program.

Venice Police Officer Paul Joyce is with his agency's Marine Unit He’s towed in the nine dolphins and rescued three manatees -- plus a turtle Thursday with FWC’s help.

He says every time his phone rings or he gets a text from Mote or a rescue group, “My heart rate goes up my blood pressure goes up. Here we go again.”

Joyce what bothers him the most is to know these animals suffered.

“Red tide is a slow death. They suffocate -- it’s like somebody putting a pillow over your face, holding it there, take it away, put it there again. It’s sad.”

This red tide is a first in his 27-year career. “In my career in marine patrol, I’ve never come across something like this. ever.”

Mote scientists Gretchen Lovewell, animal stranding program manager, says the aquarium is “preparing for this will continue and get worse.”

Lovewell says they’re pretty sure these animals died from red tide toxicity.

“We’re not seeing lesions; that’s a tip of disease. Instead, their stomachs have partially digested fresh fish and not much else, indicating its due to red tide.”

Why are dolphins affected later during a bloom?

Lovewell says, “They’re apex predators they’re eating from the top of the food. Web toxins work their way up.”

The longer the red tide bloom lasts, Lovewell says the better chance it’ll reach more dolphins … and more are expected to fall victim to this toxic algae.

“We’re planning for the worst. We don’t see an end in sight right now,” said Lovewell.

Mote reports that of the nine dolphins recovered since Aug. 7, three are males and four are females. The sex of the other two is being confirmed.

Mote reported Thursday that its staff is conducting or will conduct necropsies on all nine dolphins at the organization's main campus on City Island. It said the animals were found moderately to severely decomposed, complicating its efforts to examine and collect samples.

First, it was turtles, manatees and tons of fish; now dolphins are washing up dead, and scientists suspect it's due to red tide.

Mote scientists said when a bloom lasts this long -- and this one started nine months ago off Southwest Florida -- sooner or later dolphins will be impacted. Those scientists admitted they had their fingers crossed, hoping that wouldn’t be the case; but sadly it is.
