Telling farmed from wild salmon

I became interested in this issue because I recently had a brawl with the salesperson in a local store insisting that his salmons were caught in the wild!

Firstly, > 95% of the Salmon that you get from our local stores are farmed salmon.
If it comes from Chile/Norway--> it is almost definitely farmed.
You can't really tell the differences unless you have a fully equipped biochemistry lab to perform HPLC or spectroscopy analysing the fat oil ratios and pigments.

It is not easy to tell farmed from wild salmon

1) the fins on farmed salmon, in partucular the tail fin, more often than not will show signs of wear and will in fact be less pointed. Instead the tails will be rounded.

2) It is often easy to tell by looking at the meat. Farmed salmon is fed a high fat diet and more often than not you can see definite white fat lines between the muscle segments. Wild salmon will have a light patch, but in general farmed salmon meat has a more orange colour and will exhibit a clear white fat line.

3) If it is cheap, it is uauslly farmed salmon. So never go for discounted Salmon.

4) The taste is different. But had you tasted wild salmon before? If you haven't, then you would be able to tell as well.

Hope this info will help
