I have stocked my pond with fatheads and bluegills. I see a large amount of fry and fingerlings. Is there a way I can determine if the bluegill are spawning successfully? I have only seen one nest, and that one had several large crayfish in it with one bluegill watching them. I am worried that the crayfish aren't allowing the bluegill eggs to hatch.

Is there a way to determine the difference between bluegill and fathead fingerlings?

How can I tell if my bluegill are reproducing?

Thanks in advance.
