Sea water is a major supplier of nutritious food for human consumption. Pier seafood is found in large quantities on the Redondo Beach in CA. Several varieties of animal and plant species are classified under seafood. Seafood includes different forms of animals and plants which provide a lot of nutritional nutrients to human bodies. Animals under seafood are shellfish and fish. Mammals are being eliminated from this category because their consumption is highly reducing around the globe.
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.
Diadromous fish refer to all fishes that change habitat between sea and fresh water bodies. They are adapted to inhabit salty sea water and fresh water. Examples of organisms in this group include shad, eels, salmon, and lampreys. Lastly, as suggested by the name, freshwater fishes live in ponds, lakes, rivers, and other fresh water bodies. Examples are catfish, trout, tilapia, and carp. They are mostly found on farms. Infact, most of freshwater fishes in USA are raised on farms.
Shellfish on the other hand comprises of crustaceans, echinoderms, and molluscs. Molluscs lack hard protective structures found in crustaceans and their bodies are not segmented. They only have calcareous shells which protect them. The shell grows as the organism grows. This category has bivalves, gastropods, and cephalopods as main subgroups. Cephalopods lack protective shells.
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.
Cooked foods should be kept safely away from raw ones to avoid cross-contamination. All contaminated foods must be disposed off safely if cross-contamination is suspected. An alternative to disposal would be to feed it to farm animals like pigs. Before an after the organisms are handled, one should wash their hands properly.
