It is not certain if the red tide in SouthWest Florida will be gone by March and there have been cases of red tide lasting as long as 30 months (one red tide event lasted 30 months and it started in 1994). This has been the worst red tide SouthWest Florida has had in over a decade and it is not known at this moment how bad the fishing will be affected for next March. Many people are being affected health wise by the red tide since it can cause breathing difficulties.Red tide also contains domoic acid which is toxin found in red tide so it is not even safe to eat fish poisoned by red tide.Everything I mentioned can be researched online, including several pictures of beaches filled with dead fish, dolphin (at least 41 dolphins died from red tide this year),etc. You will most likely be better off going to SouthEast Florida and the Florida Keys where the fishing is great year round and has not been affected by the red tide. Hopefully we get a hurricane, tropical depression,etc to pass by SouthWest Florida so it can break up the red tide and move it away from SouthWest Florida.
