Fishing is a very widespread activity that puts fish on the table for many. But as the human population grows, so does the demand for more fish as food. This often results in overfishing and the depletion and even extinction of natural fish populations. Salmon is one of the most popular food fish, because it is tasty and healthy as well. But uncontrolled fishing has greatly reduced numbers of salmon in the wild and salmon have entirely disappeared from some water bodies and regions. This creates the problem of meeting market demand for salmon while preserving wild salmon populations. What is the solution?
The solution is salmon farming. Salmon farms breed and then raise salmon in tanks and enclosures where the environment and water conditions are made suitable for the salmon species. The output of salmon farms helps immensely in meeting the high market demand for salmon. But most importantly, they help in reducing the quantity of fishing and subsequently lead to increases in wild salmon populations. Moreover, salmon farming creates jobs for the local population. Salmon farms also help in growing or supplementing wild fish populations with farm raised salmon. Fish reared by way of salmon farming may also be reintroduced into areas where they have become extinct due to overfishing.
In the end, salmon farming is environment friendly. Salmon farms help in preserving ecological balance, and let people enjoy tasty and healthy farm raised salmon reared without harming nature and the ecosystem.

Every year new ingredients hit the market with promises of revolutionizing skin-care products and tapping the elusive Fountain of Youth. At times, they deliver, and substances such as retinol or peptides exceed expectations and change the landscape of skin care. Others fizzle with little or no impact. We’ve polled more than 25 experts and asked them which ingredients are worth watching (and buying) in 2009.
Astaxanthin; What it is: Described as the ultimate antioxidant by New York dermatologist Dr. Kenneth Mark, astaxanthin is up to 1,000 times more potent than vitamin E. It is also found in nature as the fat-soluble pigment found in salmon and algae.
Why it looks promising: “This is a retinoid form of vitamin A and has all the typical benefits of retinoids — providing antioxidant protection and stimulating cell renewal,” Murad says. And according to a recent study, astaxanthin decreased hyper-pigmentation by more than 40%, Mark says.

Farmed salmon’s color has long been a topic of debate. The orange hue has been attributed, based on speculation, to numerous different dyes or pigments. One of the pigments correctly named was Astaxanthin. This substance is actually a very powerful antioxidant, which is also a carotenoid pigment widely found in plants. Astaxanthin is the source of color for not only salmon in the wild, but crustaceans such as shrimp, crabs, and lobsters as well. Astaxanthin is mixed into the Salmon’s feed and is the cause for the orange colored meat found both in the wild and at the farms. Astaxanthin is naturally derived from algae, which is a main food source for small fish and krill, the pigment is then passed along the food chain to Salmon and crustaceans. In conclusion, the pigment in wild and farmed salmon comes from the presence of astaxanthin in their feed.
