A hernia is the protrusion of an organ or piece of tissue from its normally contained space. In the abdomen, a hernia usually involves a piece of bowel, or omentum, which is a fatty apron that hangs down from the midportion of the colon (large intestine), protruding through a weak area in the abdominal wall.
Haddock and Cod are both endangered species fish-we eat far too many of them. The sustainable fish that has the nearest taste to both Cod and Haddock is Polluck-lovely white flakes of meat with a very delicate flavour.
Shad are overgrown members of the herring family that live in the ocean but spawn in fresh water each spring. They're East Coast natives that are now found in abundance in the west, too. Shad may be caught for food and sport, but they're also used as bait fish for larger catches like blue catfish, bass or stripers.
