i have been told that all the salmon in Thailnd is farmed salmon and that farmed salmon usually do not have a lot of Omega 3 oils like wild salmon. Are these things true?

Mostly farmed salmon because it is cheaper. Wild catch is usually labeled as such because it is better. Not sure about how much lower the Omega 3 oils are but have read about the lower nutritional value of farmed salmon and possibly unhealthy additives in the meat from the feed and efforts at disease prevention in the farms.

concerning omega 3 levels. I found the following online at a website called whfoodDOTorg Oddly enough, the one farmed raised species of salmon it doesn't address is the Atlantic Salmon, which is by far the most widely cultivated species.

Nutritional Differences

Omega 3 Fat Content

FDA statistics on the nutritional content (protein and fat-ratios) of farm versus wild salmon show that:

• The fat content of farmed salmon is excessively high--30-35% by weight.
  
• Wild salmon have a 20% higher protein content and a 20% lower fat content than farm-raised salmon.
  
• Farm-raised fish contain much higher amounts of pro-inflammatory omega 6 fats than wild fish.
  

These unfortunate statistics are confirmed in a recent (1988-1990) study conducted by the U.S. Department of Agriculture (USDA) to compare the nutrient profiles of the leading species of wild and cultivated fish and shellfish. Three species of fish that contain beneficial omega 3 fats were included: catfish, rainbow trout, and coho salmon.

Farm-raised Fish are Fattier

In all three species, the farm-raised fish were fattier. Not surprising since farm-raised fish do not spend their lives vigorously swimming through cold ocean waters or leaping up rocky streams. Marine couch potatoes, they circle lazily in crowded pens fattening up on pellets of fish chow.

In each of the species evaluated by the USDA, the farm-raised fish were found to contain more total fat than their wild counterparts. For rainbow trout, the difference in total fat (5.4g/100g in wild trout vs. 4.6 g/100g in cultivated trout) was the smallest, while cultivated catfish had nearly five times as much fat as wild (11.3g/100 g in cultivated vs. 2.3 g/100g in wild). Farm-raised coho salmon had approximately 2.7 times the total fat as wild samples.

Cultivated catfish were the worst, with 5 times the fat content of their wild counterparts. Plus, although the farm-raised catfish, rainbow trout and coho salmon contained as much or even more omega-3 fatty acids as their wild equivalents, in proportion to the amount of omega-6 fats they also contained, they actually provided less usable omega-3s.

Farm-raised Fish Provide Less Usable Omega-3 Fats

The reason for this apparent discrepancy is that both omega 3 and omega 6 fats use the same enzymes for conversion into the forms in which they are active in the body. The same elongase and desaturase enzymes that convert omega-3 fats into their beneficial anti-inflammatory forms (the series 3 prostaglandins and the less inflammatory thromboxanesand leukotriennes) also convert omega-6 fats into their pro-inflammatory forms (the series 2 prostaglandins and the pro-inflammatory thromboxanes and leukotrienes). So, when a food is eaten that contains high amounts of omega 6s in proportion to its content of omega 3s, the omega-6 fats use up the available conversion enzymes to produce pro-inflammatory compounds while preventing the manufacture of anti-inflammatory substances from omega-3s, even when these beneficial fats are present.

Farm-raised Fish Contain More Pro-inflammatory Omega-6 Fats

In all three types of fish, the amount of omega 6 fats was substantially higher in farm-raised compared to wild fish. Cultivated trout, in particular, had much higher levels of one type of omega 6 fat called linoleic acid than wild trout (14% in farm-raised compared to 5% in wild samples). The total of all types of omega 6 fats found in cultivated fish was twice the level found in the wild samples (14% vs 7%, respectively).

Wild Fish Provide More Omega-3 Fats

In all three species evaluated, the wild fish were found to have a higher proportion of omega-3 fats in comparison to omega 6 fats than the cultivated fish. The wild coho were not only much lower in overall fat content, but also were found to have 33% more omega 3 fatty acids than their farm-raised counterparts. Omega 3s accounted for 29% of the fats in wild coho versus 19% of the fats in cultivated coho. Rainbow trout showed similar proportions in fatty acid content; wild trout contained approximately 33% more omega 3s than cultivated trout, however both cultivated and wild trout did have much lower amounts of omega 6 fats than the other types of fish.

I wish I knew if farmed salmon are still good for you.

Sardines are packed with Omega 3s, but taste like sh*t. Mackeral tastes better, but I prefer salmon.

There is no such creature as a salmon trout. Perhaps confused with a "Steelhead Trout" which is a rainbow trout that travels around the ocean like salmon for a few years before returning to it's original stream. They are as big as a smaller salmon ranging in the 10-20 lb. area. Hardest game fish to catch IMO.

One should note that Steelhead are used to quickly diagnose those who fish for them in the winter as being totally crazy and in need of counseling.

If you want some good salmon keep your eyes out for Copper River reds(sockeye) or Copper River Kings. These are the best you can do to taste fresh wild salmon without being there. Farm fish?? Keep it thank you very much.

I agree with the lackluster appeal of farmed salmon as compared to wild salmon, but the Copper River craze is, IMHO, just a big marketing scheme and not worth the added price.
