Shad is a type of fish, much valued as a sport fish. The male shad is an excellent game fish, showing multiple jumps and an occasional end-over-end; it has been called a "freshwater tarpon". The gravid female does not fight much, but is often kept for the roe. The current world record is listed by the IGFA as 11 pounds 4 ounces (5.1 kg), set at Holyoke Dam, Massachusetts, on 19 May 1986 by Robert A. Thibodo.[1]
American shad exhibit complex and little-understood feeding behavior while spawning. Unlike salmon, shad retain the ability to digest and assimilate food during the anadromous migration.[citation needed] Like other fish, their feeding instinct can be triggered by a variety of factors such as turbidity and water temperature.
