America and in Northern Europe,• some species salmon are found only in the

western Pacific Ocean in Japan, Korea, and Russia and known in the US ,also in southeast and southwest Alaska, and Canada to the Lena River in Siberia, usually in shorter coastal streams. It is the smallest of the Pacific species,.

Health Benefits of Salmon

1) Inflammation omega-3 fatty acids and The incredibly high content of vitamin D and selenium found in salmon have also been shown to be key agents in preventing unwanted inflammation.

2) Cognitive Function the benefits of salmon intake for thinking and the decreased risk of certain brain-related problems and decreased chances of depression.

• Mackerels are fast and agile swimmers. They can swim at the speed of 5.5 meters per second.

• Mackerels have long lifespan. They can survive up to 25 years in the wild.

6 -White Sea bass

Sea bass Characteristics• The more or less elongated body has small scales, the

mouth is large, and the tail is generally straight-edged or rounded.

tropical seas.• Its habitats include estuaries, coastal

waters, and rivers. It is found in the waters in and around Europe, including the eastern Atlantic Ocean.
