Fish and shellfish should be included in normal diet. Two- to three servings a week are a part of the food pyramid. Studies have shown that Omega three oils are beneficial in lowering the risk of cardiovascular diseases. It lowers the risk of arrhythmias that can be potentially fatal. The Omega three oils, which are an unsaturated fat, are found naturally in the fish. The oils absorb into the cell membranes and help to make the platelets in the blood not as sticky. It can help the plaque not to build up, which leads to a stroke or heart attack.
DHA could help to stabilize the rhythm of the heart. When people are recovering from heart attacks, this can be very beneficial. This may be able to also help regulate cell membrane functions that are a part of transmitting signals within the brain cells. All three work together to promote a healthier heart.
Humans consume a variety of fish and shellfish. The list below is divided into various groups.

The fish that has been as a good source containing the Omega three oils is Salmon. Pink and Copper River Salmon are frequently consumed. The Copper River Salmon is extremely nutritious. The fatty acids can lower cholesterol.
In a recent study conducted by the American Medical Association (AMA) November 1, 1995 tracked people who ate salmon and those who did not. The people who ate a quantity of fish that averaged 5.5 grams had half the risk of cardiac arrest and opposed to those who didn’t consume fish in the Omega three oils. The 5.5 grams balanced out to a three ounce serving of Salmon on a weekly basis. Dietary Omega three’s can be effective quickly. Within a few days to a week the oils are absorbed into the cell membranes.

As in everything, make careful selections into your diet. Fish is an excellent source of nutrition.

activity sheets (used for making model of fish)
-
crayons
-
scissors
-
live gold fish for observation (four groups)
-
tape or glue
-
journals
Procerdure:
-
Have students observe a fold fish for 5 -- 10 minutes (4 groups) asking them to locate the various fins.
-
Each group records their observations in their journals.
-
Discuss the function of each fin
-
Ask how fish are able to breathe under water.
-
Have students assemble their own fish models.
-
Students will then research fresh water and salt water fish; for similarities and differences. (2 days)
-
Each group will orally present their findings.
