The bay is a pretty open area. It would have to get pretty big. No dead fish have been reported in Corpus Christi but there were a few spotted in Port Aransas. Red tide was first spotted locally two days ago. It started near Sabine a month ago and has moved south since.
Red tide is the common name for the growth of certain types of algae in marine waters.
The algae produce a neurotoxin that can kill fish and shellfish. The lethal threshold for fish is 1 million cells of red tide per milliliter. If humans eat contaminated fish or shellfish, the toxin can cause numbness, dizziness, nausea, fever and muscle paralysis. The most serious cases can result in respiratory arrest and death.
