Deeper water does holds salinity down below the fresh water.

That so called spot that stays saltier than everything around? That stays at 5 ppm? 5 ppm is .005 ppt, which is pretty much fresh.

I fish mostly VB and do find that we can catch fish in rather muddy fresh water. They do hug the bottom with the baits needing to be slowly worked. Ever notice the color difference of specks caught in a low salinity area?
Saltwater is heavier than fresh, so, yes, the fresh sits on top. This is why they call it "The Wedge" when the Mississippi River is low and saltwater pushes as far north as Lake Jackson. It wedges underneath the river water. I've caught plenty of fish in Delacroix when the river water was on top.

Ah, that makes more sense. Still not that salty, but way more believable now.

Was playing Army in Belle Chasse after Katrina hit and we would get off work and catch limits of redfish right off the bank of the MS River there in December. Water was at pool stage, no rain, had almost 2.5 feet clarity in the MS RIVER! Was awesome, the catfish would bite at night and they were slap full of corn from where they loaded corn onto the barges, a few rains up north sent the reds back south though.

Redfish or speckled trout? Do redfish have a higher tolerance to fresh water in respect of salinity being low from the top of the column to the bottom?

Redfish can take freshwater and lower temperatures better than Trout.
But that don't mean there are no Trout there. Just not as many as Reds.

Like Ray said, redfish can be caught in almost pure freshwater at times.

Redfish can actually live in freshwater lakes they just cant spawn in freshwater

I would think (I have only fished W's Lake ten times or so, so no expert) that the LNG canal would be plenty salty still after this rain. It is deep and sheltered from a large influx of freshwater, there is only that one little bayou that runs into it. Even when the main lake looks like hot chocolate after a big rainstorm, that canal is always clear. That is where I would be if I had to go this weekend to catch trout.

my guess is probably has something to do with the density of saltwater makes the eggs more buoyant. Im not sure if they dont produce eggs in freshwater or they just cant fertilize them

Most "salties" can't reproduce in freshwater because it takes more energy for them to survive in freshwater.....same principle that allows bullsharks to live in freshwater, they adjust the amount of urea they excrete so that they do not absorb too much water....but, it takes more energy to do this, and that is why they generally can't reproduce in freshwater...its a lot of chemistry that I dont want to bore anyone with, but that would be my best explanation for the phenomenon...

Please bore us with the chemistry. The audience here seeks to learn more about saltwater fish and the reproduction.

I catch reds in grand lake when the water is as salty as toledo bend,don't bother them one bit. Trout are a lil more picky.
