I don't know if this has been posted here before but the video at the following link is pretty convincing and in some spots, very enlightening. I never knew that some hatchery smolts could actually spawn immediately with wild fish right after release due to premature fertility. Or that large smolt releases ring the diner bell for predators that normally would not have been alerted...and the wild smolt get gobbled up as a result.
