Using common fisheries monitoring techniques, combined with social surveys, at nine Alberta lakes, I quantified three main assumptions behind put-and-take stocking. Surprisingly, 1) stocking high densities of Rainbow Trout created very low-density populations; 2) these populations supported mediocre fisheries; 3) these mediocre fisheries, if above a threshold catch rate, attracted very large numbers of satisfied anglers.
