"For the 1996 spawners, the wild hens produced an average of 3.6 adults in the next generation; the hatchery hens produced 0.4 adults per hen. For the 1997 spawners, each hatchery hen produced 0.2 adults on average, each wild hen produced 6.9 adults in the next generation (2001 returns). "

That is fascinating! Where and when can this research paper be read? If this research holds and translates to other systems, seems like hatcheries are on their way out. Shut all the hatcheries down and allow only catch and release for 10-20 years and we may be way ahead. Would be a tough first 10 years though.....
