Anadromous fish of Shad

Shad are anadromous fish (ascend rivers to spawn) that spend the greatest part of their lives in ocean waters as far as 50 mile (80.5 km) from shore. Shad are plankton eaters and are said not to eat fish.

They range from the Gulf of St. Lawrence to Florida on the East Coast, but are caught in significant numbers only from New York southward. They were brought, some years ago, to Pacific waters, and some are now caught in California. Shad are caught in rivers and their estuaries with drift grill nets. Aboard the boats, they are neither eviscerated nor iced, since they are brought to shore shortly after removal from the water.

Shad are used almost entirely as the fresh product, with only small amounts being frozen. They contain many small bones, but can be filtered to eliminate most of them from the flesh. The roe (unfertilized eggs), which prior to spawning is held together by a thin membrane, is highly prized. It is sold fresh, or packaged in moisture vapor-proof material and frozen to be sold to the restaurant trade and in this state, may be stored at 0 degrees F for 6 to 8 months. Longer storage under this condition usually results in a rancid product due to oxidation of the fats contained therein.

Stingray fish

These fish are widely distributed in oceans and rivers. Stingrays are members of the elasmobranch family a family of fish that includes sharks, marine and freshwater rays and sawfish.

It is a broad, flat fish with a long, whip like tail that may have one or more stingers with barbed ends.

Elasmobranch fish are unique in many ways. They do not have scales; in the place of scales, their skin has dermal denticles, giving it the texture of fine sandpaper. They do not have calcified bones; instead, their skeleton is composed of cartilage.

Stingrays bury themselves in the sand of shallow water, where they can be easily steeped on inadvertently.

The large barbed spine may cause severe and even fatal lacerating injuries, usually to the lower part of the legs but occasionally penetrating the body cavities, heart and viscera when the swimmer falls and lies on, or even swim over the fish.
