that is one fat carp. Around here, creeks & tributaries flowing into the Delaware River, about all of the ones that large or larger have wallowed in the mud and sucked mud so long, they DO NOT taste good. I bet the roe would be OK, though.
crawdads are becoming available up here in the N.E. U.S.A. but so far they do not compare with the quality of fresh stuff I eat when down in the New Orleans to Houston strip.
