Oh, dear :spls:... uranium glass was used frequently on Murano. And eyes were impressed just about as often as they were applied. I feel your fish is Murano. I didn't answer because I didn't know who made it. Several companies did fish that look similar. I recognize the base from somewhere and searched my files, but could not locate it. I have seen it quite a few times. Without any further evidence, I would say most likely a very nice vintage Murano fish.
