NAPLES, Fla.- An investigation is under way regarding a large-fish kill on Vanderbilt Beach that was discovered Monday morning.

Sea turtle monitors revealed the fish kill and report that it stretches from Vanderbilt Beach down to Park Shore Beach. The kill involves multiple species, including sharks, rays, skates and lobster.

While several animals have been washed up on shore, not all of them were dead.  Many were trying to avoid the algae bloom, ending up on shore.

Rhoda Watkins, an environmental specialist, told WINK News that the cause is most likely due to an algae bloom, but she will be taking samples for a definitive answer. Water test results take 24 hours to return, but tissue tests can take much longer.
