So you’re comment, “There should be no fossils of aquatic animals to speak of, since they wouldn’t have been killed, and therefore wouldn’t have left any fossils behind.”, is at odds with reality.

I've gotten conflicting information about what happened during the flood. Some say Noah didn't take any fish aboard the Ark, because he didn't need to. Others say the conditions in the oceans were such that there is very little if any chance that anything could have survive in them.

I think if we go to the source we find animals were taken aboard according to “clean” and “unclean” classification. While I'm not certain what made an animal one or the other probably it was on the basis of suitability for sacrifice.

Haven't heard of fish being used in sacrifice so I would assume none were taken on the Ark.
