i have seen "fresh wild steelhead" on sale at Albertsons before. i asked the manager one time about this and he told me they are always from a fish farm, he also said that he has been asked before about this and the only reason they are advertised as wild is that they sell better than if they were advertised as farmed. since they are raised in the saltwater in pens (i.e. in the wild) they qualify as wild fish in the markets eyes.

it seems it would be much cheaper and consistently available to buy from farms, i would think every grocery store that has them gets them from fish farms.
