Please help identify these chinese fish bowls??

I'm inquiring about these chinese fish bowls. I do not know much about them and unfortunately,they do not have any markings as to the dates of them - which leads me to believe they are reproduction or knock off fish bowls. I've attached two pictures of each bowl - one outside and one inside shot. Any information on what they might be would be of great help. Thanks so much!
