There are several farms growing Pacifics now.
And if you buy Alaskan 'wild' salmon, then you have a roughly 1 in 4 chance of eating something that began it's life in a hatchery. Some of those 'wild' fish are held in cages to grow larger than the wild smolts before release. Though that's for all salmon, for some species/stocks the rate is upwards of 50% hatchery stock.
Yet again, aquaculture research making a big difference to the wild fishing industry.
This is a fact that was conspicuously absent in that waste of money Cohen Commission, as was the waste in the form of by-catch for the International commercial fleets in the Gulf of Alaska. All we did as tax payers is educate some lawyers on fishery management and biology.
