There is a concern about them eating the small crabs, similar to the rockfish. They will certainly out bread any other species of fish. With this in mind, in time they may very likely push out other species. As for the water, the salinity is something they can adapt to. These are very unique fish. Remember, they have the ability to live out of water for a period of time. I know of no other fish with this ability. We, the public, can kill can or eat as many as we can find. There will be thousands to every one we kill it sounds like. The only way to get rid of them, is to eliminate their food source. Their food source is every fish the bay has to offer. If they are hunger enough, and all the other food is gone, I wonder if they would attack skates? Wouldn't that be nice. Their teeth are certainly strong enough to tear them a part. The State does not believe they will be a threat to people. That is until something happened?
