A new study coming out of Idaho highlights some very interesting new insights into how wild and hatchery steelhead interact and co-exist in the river. According to new research shared by Idaho Fish and Game, “Idaho’s wild steelhead are caught by anglers less often than hatchery fish, and survive at a very high rate after being caught and released.”
The study also showed, “Wild fish and hatchery fish naturally segregate in rivers, and anglers target hatchery fish more often.” Meaning that you’re more likely to catch a hatchery fish than a wild steelhead at this point. What’s more interesting is the fact that hatchery fish and wild fish tend to segregate, preferring to stick with their own kind.
The research and press release can be found here and are well worth a read for the inquisitive steelhead angler.
