Yup sixty's and seventy's were the peak of hatchery production, huge commercial fleets targeting them, every thing from sport boats with hand cranks to commercial trollers. Land use laws were lax or non-exsitent, so habitat was just bulldozed under, didn't need it, we had the hatcheries. ESA listings followed in the eighty's along with the Boldt decision, and its been a quagmire ever since.
