FISH + SEX - OXYGEN = FISH KILL


We have been receiving calls about many dead fish in our lakes. Our CAM Rodger Carver has researched this matter and has been in communication with Lake and Wetland Management, and they have been studying our big lake . The fish have been identified as Shad and the most likely cause is related to spawning and a resulting increased need for oxygen. It should be pointed out specifically, that there is no indication of any sort of toxicity being involved.

A very informative publication of the University of Florida Extension Service may prove instructive:

We continue to monitor the condition of the lakes.

  1. Stress from shoreline renewal may be an added cause, but the birds are enjoying something. Three beautiful white (morph) Florida Great Blue Herons are fishing together every day, could be Great Egrets too. Quick what color are their legs, egrets have black legs.

  2. Maybe turning on the aerators would help.
