I've caught several of them out in front of Pigot Bay in PWS...but none of them as large as the one pictured. I let most of them go but they do have nice, long filets but they're almost too mild in flavor for my taste. The toothy buggers have a will to live and will bite you if given the opportunity.
I caught a wolf fish a bit bigger than that on the East side of Knight Island. The larger ones that are brown are females I guess. We let her go, but I ate one that I caught on the East coast off of Plymouth Rock and it was very good.
