What is a Fish?
A "fish" is any vertebrate animal that lives in water, is covered with scales and moves about with fins. Fish abound in most aquatic environments, from oceans to mountains, in freshwater and seawater. Fish is a vital source of food for most people. Fishes like sharks horrify humans, and fishes like goldfish entertain humans.
Suggested Eating
Popular to serve as a main dish, salmon provides a tender, flaky-textured meat with a mild to rich flavor, depending on the species. Salmon can be prepared in almost any manner, such as smoked, baked, broiled, grilled, fried, or poached.
Smelts are sold, cooked and eaten whole. They have a rich, oily flesh with a mild flavor.http://www.recipetips.com/kitchen-tips/t--1228/types-of-fish.asp
Tuna and sardines are two of the world's main seafood sources.
Varieties and Characteristics
Yellowfin tuna, albacore tuna, cod, and Alaska pollock, which are often used for food, are seawater fish. Popular varieties can become overfished. Atlantic cod, monkfish, and bluefin tuna are three varieties that need time to repopulate. However, as long as consumer demand remains at a high peak, they may possibly become endangered species. http://www.thenibble.com/reviews/MAIN/fish/seafood/seafood-glossary.asp
Salmon and smelts are both anadromous fish, which means that the fish is born in freshwater, then migrates to saltwater to mature and then returns to freshwater to spawn.http://www.recipetips.com/kitchen-tips/t--1228/types-of-fish.asp Salmon originated in the Atlantic and Pacific Oceans, but are now grown in most locations where there is cold, protected seawater.
Smelts are a very small silver-colored fish that have a tint of green coloring on their back. The best season for smelts generally starts in September and runs into May. They are generally found ranging in size over three inches to under eight inches.http://www.recipetips.com/kitchen-tips/t--1228/types-of-fish.asp
