Assumptions, assumptions, assumptions. Assuming that the conditions in the sea were as you say, assuming that micro-evolution doesn't explain these things, assuming immediately that the Bible is wrong and science is write. Well, you know what they say...

Assuming that the conditions in the sea were as you say

I assume the flood was freshwater, and that freshwater floats on saltwater. Mixing a volume of freshwater you need to cover the earth to 20,000 feet, with the oceans, would still kill almost all of the ocean fish, and liekly the freshwater fish as well.

micro-evolution doesn't explain these things

Changing a pike to a cod ain't microevolution. And if you can change a lake fish to an ocean fish in 4000 years, why can't you change an ape to a human in 5 million?
