You don't have to go out on the lake - you can fish from Zipprer Creek, which extends from the lake through the park. And also at Myakka River SP, near Sarasota, you can fish on the bank. Camping at Myakka is nice, but don't go in the rainy season, or your campsite may be closed for the flooding. We cover everything from camping to wildlife watching to renting canoes. As far as algal bloom goes, there's the harder part.
Many people are familiar with the red tide that appears in the Gulf of Mexico.
In freshwater, however, the little annoying organism is similar, but a bit different, from what I understand. Algae, along with plants, are primary producers. Oligitrophic lakes have few nutrients. They are characterized by small amounts of plants and algae, clear water, and little sedimentation or muck on the bottom. As lakes age, they become more eutrophic as nutrients from their watershed are washed into the lake.
