I will try and keep the info. There are several types of toxins that the different little critters produce, but most of them are neurological. Red tide results in massive fish kills and can cause death in humans if shellfish that has concentrated the poison, is eaten. NO B.S. Brown Tide is attributed to one specific species of dinoflagellate, I can't remember which. It does just what The ONE says.
Fish can even eat the brown tide organism with no ill effects.
There has been some research done into making the creatures more digestable, but it involves spraying chemicals in the water, and I don't want anyone spraying anything in our water. South of Baffin the water is real nice. What may have happened is the resent rains lowered the salinity down there. You see, brown tide can t live in sea water salinity levels because its to fresh. Hopefully we ll get some more rain tonight.
