I have muskrats also. I was thinking about putting a couple of same sex mink in the pond to execute the 'rats. Comments please.....
I agree with Attica Farmer - no way on the mink! Muskrats won't eat your fish, mink will. Trap or shoot the rats. A breeding couple will produce as many as 20 - 25 babies yearly from some reading I've done on them. I have them in my larger pond and they did some damage to my dam such that it will now need to be replaced at considerable freaking expense.
I am as anti-muskrat as I am anti-watermeal!
