Try this link below for sheep head recipes. I tried a couple on the grill last year and they were actually very good, a lot like red drum, but they can't be frozen.

I definitely do not agree with killing native species including sheep head. That is not sportsman like and actually displays an ignorance of the issues. The walleye population is not down because of sheep head but because of low walleye fry recruitment each spring, not because of the sheep head population. This level of walleye population is considered maintenance by the ODNR and is normal. If we were to push for anything in my opinion it would be halting commercial fishing in the US and in Canada and putting a stop to snagging walleye off their spawning beds every spring. Any way enough politics, try the link below.
