Doubt your cattle could feel a crawfish pinch if they ever actually pinched one.
Crawfish can make good food for your fish in the pond.
You might pay some attention to what kind of crawfish you introduce as some are known to borrow small holes around the pond..
Im sure some of the experts here can help out with more information on what type to consider stocking and what might needed to get them established.
