An estuary is a partly enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea

The problem is that this is a global flood and is not coastal. Plus the water coming would be all fresh and would eventually take over. Also not all fish can survive in estuaries. You really just made a point that was useless because it defeats the whole global flood thing(being that there was land) and if not still doesn't get rid of the fact we should have no salt water fish in there was a global flood.
