![]() ![]() Fish Health in the St. Lucie Estuarine SystemPoster presented May 1999, at the South Florida Restoration Science Forum
Poster presented by: Patti Sime, SFWMD
Photos by Michael Kandrashoff For decades, fish with lesions, ulcers, hemorrhages, fin erosion, skeletal or fin deformities, scale disorientation, or other problems have been observed in the St. Lucie Estuarine System. A growing literature supports the concept that the percent of fish exhibiting externally visible abnormalities such as these is indicative of water quality and the ecological health of the water in which they live.
