It takes several minutes in a zippy speedboat to travel far enough offshore to see one of the buoys up close.<\/p>\n<p>On the way, one of the scientists in the boat captures a jarful of water and holds it up to the light.

There&#8217;s fishing tournaments and just recreationalists.\u201d<\/p>\n<p>When the algae gets bad, it sucks up all the oxygen in the water, which causes mass fish kills.
