Just some friendly interesting info to share.
Recycling does not harm "Wild" Steelhead in the Cowlitz
Cowlitz Summer Steelhead Recycling Study
The U.S. Geological Study study, funded by angler dollars, involved nearly 550 fish tagged at the Cowlitz Salmon Hatchery in summer 2012 and then released near the I-5 bridge below Toledo. He says half of the fish returned to the hatchery, and averaged nine days to do so.
Just under one-fifth of the steelhead were caught by anglers within a week and a half, Thomas says.
Angling was better when flows out of Mayfield Lake were declining while the fish tended to skip bait and hit the barn when volume was on the upswing, he reports.
Some of the steelhead were radio-tagged, and all but one of those stayed out of the tribs; the one that wandered spent seven days in the Toutle. Telemetry also showed that a third of the fish made anywhere from two to six trips from Blue Creek up to Barrier Dam, Thomas writes.
He reports that USGS's executive summary for the preliminary study results reads, "Intensive monitoring of the key spawning tributaries failed to detect a single fish during the spawning period."
