Shad is a fish similar to herring, but with a fuller body and is considered a delicacy for its rich flesh. It is native to the Atlantic Ocean and has also been transplanted to the Pacific coast since 1870. Shad roe is a particular delicacy.
Shad, the collective name for various white fish species within the herring family, holds gastronomic significance primarily in North America, with the American shad being the most esteemed. Similar to salmon, shad embarks on a remarkable migration from the sea to rivers for the purpose of spawning. Consequently, it is only caught during the winter months. Shad comes in several types, varying in length from approximately 1 foot to 3¼ feet.
