Salmon, also known as salmon, is a kind of deep-sea fish and one of the commonly used foods. Salmon live in the Atlantic and Pacific oceans and can also be found in the Great Lakes of America and other lakes.

Salmon was born in fresh water, then moved to seawater to grow, and then returned to fresh water to breed. Legend has it that salmon will swim back to its birthplace to breed, and research has found that 90% of salmon that swim into a stream are born in the same stream, but how they know how to swim back to the same stream is still a mystery. Pacific salmon usually die a few weeks after breeding.

Salmon is a popular food and a very healthy food. Salmon meat is high in protein and OMEGA-3 fatty acids, but low in fat. Salmon meat is orange, which is a red-fleshed fish, but there are a few wild species with white meat.

Most salmon produced in the Atlantic Ocean is 99% farmed, while salmon produced in the Pacific Ocean is more than 80% caught in the wild.

There are many ways to eat salmon. The Japanese will make salmon head into salted salmon and other dishes. Europeans and Americans will make smoked salmon by hot or cold smoking, or can salmon for storage. Because raw salmon meat contains marine gastronematodes or marine parasites, salmon will not be eaten as raw fish before the invention of cold storage.
