A lot of human food is found in large quantities in the sea. One of the place on the globe that is rich with pier seafood is Redondo Beach CA. Seafood includes various forms of animal and plant life which supply human diets with nutrients of different kinds. In the US, animal seafood consumed by the citizens is made up of fish and shellfish. The reduction in the rate at which sea mammals like dolphins are consumed has made them not listed among seafood these days.
There are many classes in which fishes can be placed into. The classes depend on migratory behavior and the water depth the fish lives in. Major groups are diadromous, freshwater fishes, marine demersal, and marine pelagic. Fish that live at or near the surface are known as marine pelagic. They also get food near the surface. Larger species in this class are salmon, marlin, shark, swordfish, and tuna while small species are menhaden, herring, sardines, and sprats.
Demersal fish include all fishes that inhabit the sea bed. They find their food sources from the seabed. Their major food source is crustaceans at the seabed. The flesh of these organisms is whiter than that of those in the marine pelagic category because they do not have strong muscles for swimming. Examples include flatfish, stingrays, cod, and grouper.
Fishe species that alternate habitats between fresh and sea water masses are called diadromous fish. They can live in fresh and salty waters. Examples of organisms include eels, salmon, lampreys, and shad. Lastly, like the name suggests, freshwater fishes inhabit lakes, rivers, ponds, and other bodies with fresh water. Examples are trout, tilapia, carp, and catfish. They are mostly reared on farms. Infact, they contribute to the largest portion of freshwater fishes in USA.
On the other hand, shellfish comprises of molluscs, crustaceans, and echinoderms. Molluscs do not have segmented bodies or any hard protective structures like crustaceans. Instead, they have calcareous shells which provide protection to the soft tissues of the body and grow as the organism grows. Major groups in this category are bivalves, gastropods, and cephalopods. Cephalopods are the only organisms in this group that lack a protective shell.
A protective shell in crustaceans is made of chitin. When cooked, the shell changes color to pink or red. Crustaceans are found at varying depths of the ocean. Some are found at the surface and others at the ocean bed. Key sub-groups in this category include shrimps, lobsters, krill, and crabs. Different species of organisms are found under the sub-groups named above.
Broiling, frying, grilling, smoking, steaming, baking, and roasting are some of the preparation methods one can use. If preparation instructions are followed carefully, one can make very delicious meals through the methods. Seafood can be eaten alone or together with vegetables, fruits, or other foods.
To prevent cross-contamination from happening, all raw foods must be kept away from cooked ones. In case of cross-contamination, proper disposal of the food should be done. Alternatively, the contaminated foods may be fed to animals that are not affected by the contamination. Proper washing of hands should be done after and before handling the organisms.
