State officials are reporting that the red tide is showing a decline off the shores surrounding South Padre Island.
The Texas Parks & Wildlife Department (TPWD) reported a decline in the deadly algae on its website Friday.
TPWD officials reported that South Padre Island has seen a decline in cell counts.
No cells were seen in the water samples collected Wednesday from the Queen Isabella Memorial Causeway in Port Isabel.
State biologist did not find any red tide algae cells in a sample from a Gulf of Mexico beach at the UT-Pan American Coastal Studies Lab on South Padre Island.
The seasonal algae bloom grows larger in some years than others depending on water and weather conditions.
It creates toxins in the air and water and has been blamed on numerous fish kills along the Texas gulf coast.
