Big Spring (Missouri), and the Huanglong Valley.
Some fish live only in cold, clear mountain lakes; others in brackish swamps. Some depend on splashing, rocky, oxygen-rich creeks, while others, such as a freshwater dolphin, a manatee, and a thirteen-foot catfish, live only in the sluggish Amazon. In all these instances plus many more, the environment provided by the deluge waters would have no more suited these creatures than it would have the desert tortoise or the polar bear.

"fish have mechanisms that can find their way through varying salinity"
Thats a total assumption on your part with no evidence to back it up.

1. Taste Buds: Located primarily on their lips, gills, and barbels, these specialized sensory organs contain taste receptor cells sensitive to different chemical stimuli, including salts. Specific cell types within the taste buds respond to changes in salt concentration, sending signals to the brain for interpretation.
2. Olfactory Cilia: These hair-like structures lining the nasal cavities also play a role in salinity detection. Certain proteins embedded in the olfactory cilia recognize dissolved chemicals, including salt ions, triggering neural pathways for further processing.
3. Osmoreceptors: These specialized cells are distributed throughout the body, particularly in the gills, kidneys, and intestines. They directly sense changes in the salt concentration inside their bodies compared to the surrounding water. This internal-external comparison allows for adjustments in water and salt balance through mechanisms like urine production and gill permeability.
4. Lateral Line System: This sensory system composed of neuromasts runs along the body and head of fish. While primarily responsible for detecting water movement and vibrations, some neuromasts might also contribute to salinity perception by interacting with changes in water density caused by varying salt concentrations.
5. Behavioral Adaptations: Beyond purely sensory mechanisms, fish demonstrate behavioral changes in response to perceived salinity variations. For example, some species might avoid areas with sudden salinity shifts, while others actively seek out optimal salinity ranges for breeding or feeding.

Dude I'm a Marine Biologist and have a degree in Ichthyology .
Nice. I was responding to kurokage though, he was saying there was no evidence that fish have any way of detecting salinity lol.

The entire ocean would have now looked like this...
I know it wasn't your intention but I think I saw a fish hanging 10 on one of those branches. Must have been one of god's chosen fishes.

I didn't say they couldn't detect it, I said they couldn't survive the journey through a deluge washing machine ocean.

(In this study, ‘water’ refers to any water-related species such as hydrogen, hydroxyl and/or molecular water detected as O–H stretching with infrared spectroscopy.)
The deposit represents a time when the region was dominated by a tropical rainforest, and consists of an enormous quantity of sedimentary rock. This material was deposited by rivers and flood water moving northwards, leaving behind sediment that subsided between two fault blocks: the Cobequid Mountains and Caledonia Mountain (present-day Caledonia Mountain, New Brunswick), both of which were active in the Carboniferous.[22] Halokinesis along basement faults sped up the process of subsidence by removing subsurface salt from the ground. The high occurrence of flooding events in the Joggins Formation suggests that the territory rapidly subsided into the Cumberland Basin.[11] Sand from a crevasse splay may also have been responsible for intermittently burying the region and preserving its biota as fossils.

Great, there is water there, a butt load, but you still have not told us how it gets forced out.
What took its place when it did get forced out?
Stop moving the goal posts. When I said "fish have mechanisms that can find their way through varying salinity", you responded and said:
