6Mercury in FishCan be dangerous to humans especially in the early yearsSettles on the bottom of water ways and is absorbed by plankton, which is eaten by small fish. These small fish are then eaten by larger fish, which are eaten by even larger fish. It ends with a deep sea fish, like tuna, which absorbs the mercuryFish that have high mercury levels include: tuna, shark, swordfish, king mackerel, and tile fishFish that contain low levels of mercury include: canned tuna, salmon, pollock, catfish, sardines, and herring.
7Shellfish shell but no spine or bone Generally have a mild, sweet flavorMost come from oceans and seas, very few from freshwaterCrustaceans-have long bodies, jointed limbs, and are covered with a shellCrabs, crayfish, lobsters, and shrimpMollusks-have soft bodies covered by a rigid shellClams, mussels, oysters, scallops, and squid
8Inspection and Grading Hazard Analysis and Critical Control Point (HACCP)Identifies and prevents hazards that could cause food borne illness during the stages of fish productionA voluntary program is also carried jointly by the RDA and the National Marine Fisheries Service of the U.S. Department of Commerce
9Buying Fish and Shellfish Whole: sold as caught and most perishableDrawn: whole fish with scales, gills, and internal organs removedDressed: drawn fish with head, tails, and fins removedFillets: sides of fish, usually boneless, cut lengthwiseSteaks: cross sections cut from large, dressed fish.

11Cooking Fish Cook fish 10 minutes for every inch of thickness Fish will be opaque when finished cookingCooking methods for fish includeBroilingGrillingBakingPoachingSteamingBraisingFrying /Deep-Frying
12Cooking ShellfishShellfish needs to be cooked for a short time at a moderate temperatureEach type of shellfish is different so cooking methods may varyThe shells turn bright red, orange, or pink and the flesh becomes opaque when crustaceans are thoroughly cookedMollusks become plump and opaque when cookedBoth fish and shellfish are tender and cook well in the microwave in short amounts of time
13Fish and shellfishWe should be eating at least two portions of fish a week including one of oily fish.Fish and shellfish are good sources of a variety of vitamins and minerals, and oily fish is particularly rich in omega 3 fatty acids.
