Been living in Florida for last few years and have fished a location, Fishbone Creek, a tidal creek through salt marsh located Florida Central Gulf Coast. Today went out and for the first time saw a Gator less than 100 yards from where the creek dumps into the Bay. Over the last 2 weeks area has had allot of rain, water was tainted and only bite was hard head catfish. I am assuming there is a large concentration of freshwater in the creek and salinity levels are low, why alligators might venturing this part of the creek. Question, How much influence does freshwater run off in these tidal creeks have on trout and reds?? Do they seek water with higher salinity levels??
Lots of influence... saw the same thing with a bone fish flat near Snapper Creek in Biscayne Bay, Miami after rains, saw the same thing pier fishing when freshwater from Jupiter Inlet pushed southward to Ft. Lauderdale area (the color difference made it easy to see) and fishing reports would always mention it.
Same thing with reds and trout.
The key is not if it effects the fishing, but to act like an expert and give your other buddies some solitude in getting skunked as well. You'll want to scoop up a handful of water under you, look at it, smell it, then taste it. Next you'll want to spit it out in disgust, then tell everyone, " ain't no fish to be caught here". Trust me, they'll be impressed.
Don't use that for excuse too often or they'll catch on.
A good rule of angling philosphy is not to interfere with another fisherman's ways of being happy, unless you want to be hated.
