Brook trout, the only species native to Pennsylvania, is a state fish, symbol of wildlife and clean water, and is extremely struggling.
Climate change, the disappearance of hemlock shadows caused by invasive insects, and pollution are expected to wipe out colorful fish in most areas of Pennsylvania over the next 50 years.
In addition to these fateful threats, the Pennsylvania Fish and Boat Commission stores non-native, overwhelming hatchery trout in streams used by wild brook trout, explains the Pennsylvania chapter of the Native Fish Union. ..
“This is full coverage to save this species,” says Jim Slesky, fly trout enthusiast and Hershey’s physician.
At the heart of the group’s claim is that the Commission stores hatchery-raised non-native brook trout and rainbow trout in waters where hatchery fish can invade, extrude and eat. It is irreparably damaging to the last stronghold of wild brook trout. Beat them for themselves and for the food.
âWe are not advocating anything from left voltigeurs here. It’s happening elsewhere, âsaid Philip, president of the Pennsylvania branch of the Native Fish Union and a resident of Bedford. The lights add up.
With an ongoing change.org petition (Lanc.news/brooktrout), the group is urging the Fish and Boat Commission to end the practice of storing water in the presence of wild native brook trout. To date, we have over 1,500 signatures.
The petition cites 39 studies showing that the interaction of wild brook trout with hatcheries and even exotic wild trout is harmful not only to brook trout but also to aquatic ecosystems.
For example, a study by the Minnesota and Wisconsin Natural Resources Agency found that more aggressive brown trout occupied brook trout’s preferred resting place, ate brook trout larvae, monopolized spawning grounds brook trout and made brook trout vulnerable to disease. I discovered that
Studies have also suggested that brown trout hunt brook trout as climate change warms stream temperatures to marginal levels that trout can survive.
In another study, brook trout were monitored before and after removal of middle brown trout. After the brown trout were expelled, brook trout increased in number, grew larger, and survived longer.
âAttempts to increase brook trout populations through flood reduction and habitat improvement management practices are only effective if brown trout are also managed,â the study concluded.
A study by scientists at Missouri State University found that breeding non-native trout can destroy not only brook trout, but the ecosystem of streams as well. This is because amphibians, including the endangered Hellbender in Pennsylvania, essentially recognize the scent of chemicals emitted by predators and swim and hide.
However, even with the introduction of brown and rainbow trout, it has not evolved, so it is less vigilant and more likely to be eaten.
Some of the comments on the petition came from residents of Washington County: In the name of preserving nature, it’s not scary to release the same fish into a creek where our native char still exist to please Weekend Warriors. end destroyers and destroyers. “
Indeed, the Director General of the Fish and Boat Commission strongly opposes the damage caused to brook trout by the discharge of the 4,600 mile stream. Dave Nihart, head of the agency’s fisheries management department, said he is not stocking waters with high populations of brook trout.
He called the use of brook trout in 980 miles of water “unrealistic” and “many wild trout in streams where recreational trout would not be caught if not released.” We are proud to offer trout fishing opportunities while preserving our resources. “
He suggested that efforts to save brook trout should be united around creating better conditions for riverine habitat.
“It is not necessary to eliminate breeding farmed trout in all waters where wild brook trout are present, and it does not improve the quality of the wild brook trout populations present in the area. these sections.
Wright and Thresky could no longer argue. The Commission’s position does not consider how far brown trout and rainbow trout will travel to invade the waters of brook trout. They also say that brook trout need and do not allow the use of fertile water where lows occur except during the hottest seasons.
In short, the Commission does good to improve the quality of the flow of trout statewide, but believes that its primary mission is not to protect, but to meet the recreational wishes of anglers. They say they are
Wild brook trout resources.
âTrout release is a state social program governed by politics, not science,â says Suleski. “These trout are political pork to entertain people, not to protect the ecosystem.”
The group wanted the petition to get more signatures so far. And we know that the story of the reduction in trout numbers in the put-and-catch hatcheries is confusing many fishermen.
However, Suleski and Light believe that more fishermen will be involved once they understand what is really going on.
Too many fishermen believe that the release of streams and trout lives in peace and harmony and occupies their niche, they say. âThe discussion is always organized from the level of satisfaction of the fisherman, and not from an ecological point of view,â explains Suleski. âFor anglers, humans don’t always make the best decisions about what we want,â Wright adds.
âWe are witnessing a silent genocide in our state,â says Suleski.
