During the flood, how did the fresh water fish survive?

Answer:

This question assumes the oceans were salt water during the flood like they are today. I believe the entire world was largely fresh water. Today about 30% of the rain water washes into the oceans, bringing mineral salts with it. The oceans are getting saltier every day. Today’s oceans are about 3.6% salt. Between the salts washing in from ground water and the salts leaching in from subterranean salt domes, the oceans could have gone from fresh water to 3.6% in the 4400 years since the flood. If the earth were billions of years old, the oceans would be much saltier – like the Dead Sea or Great Salt Lake.

Many animals have adapted to the slow increase in salinity over the last 4400 years. We now have fresh water crocodiles and salt water crocodiles that are different species but probably had a common ancestor. This is not evolution. It is only variation. Changing from a fresh water croc to a salt-water croc is not a major change compared to what the evolutionists believe. They think it changed from a rock to a croc! That would be a major change!

Several years ago, a man in Minnesota told me that he had two large aquariums in his house, one fresh water and the other salt water. He wondered if he could mix the fish together so he figured out how to slowly raise the salt content in the fresh water aquarium a little each week for 10 years until it was 1.8% salt. At the same time, he was lowering the salt content in the salt water aquarium to 1.8% salt. After 10 years he mixed all the fish together. He told me they adapted fine.

Noah had no problem with drinking water during the flood and the fresh-water/salt-water problem does not exist. Attempting to force the way the world is today onto the questions involving the pre-flood world is a common problem. II Peter 3 says the scoffers of the last days will be willingly ignorant of how God made the heavens and the earth (the original creation), and the flood.
