Were the waters in Noahs Flood salt or fresh water or brackish?

Question

If it was fresh water how did the salt water fish survive if salt or brackish waters how did the fresh water fish survive?
How did the bottom dwelling Crustations and Shell Fish survive the sudden increase in water pressure or the Corals survive the sudden depth changes and increased sedimentation??
The only answer was that Noah must have had huge oxygenated aquariums on board the Ark for every aquatic creature or the whole story is bunkem.
Which is more likely?

Answer 1

Probably the water came in three waves fresh , then brackish ,then salt water killing the aquatic life serially.The surviving species must have been in those aquariums you suggested. Ha!

Answer 2

Because it was rain, it had to be fresh.
And as the water covered the whole surface of the ground, it probably took on salt from the ground.
And do not forget.
Jehovah god can protect whoever or whatever from anything.
the Bible does not say, but commonsense would tell us that god did preserve his fish creation. How he did it we may never know.
But it is a good question.

Answer 3

i do not believe in god however i can answer this it is a standard mantra of those who do believe in god .. with god all things are possible======more than likely the story as you put it is bunkem
