Wyoming Game and Fish Department Press Release
CHEYENNE, Wyo. — The Wyoming Game and Fish Department (WGFD) is asking anglers to adjust their fishing practices as summer temperatures climb.
“It’s that time of year when water temperatures are highest. Warmer surface temperatures have the potential to be lethal to trout,” Fish Division Chief Alan Osterland said in a press release. “Warm water also holds less oxygen which can stress not only trout, but also all fish.”
According to WGFD, trout die after prolonged exposure to water hotter than 75 degrees Fahrenheit, and brief exposure to water hotter than 80 degrees. Warm water carrying less oxygen also increases fish stress, which hinders fish survival after catch and release.
“As water temperatures increase, anglers should monitor water temps while fishing. When water temperature hits 70 degrees, we recommended that anglers should stop catching and releasing fish,” Osterland said. “Practice self-restraint to help fish survive.”
WGFD asks all anglers practicing catch and release to consider the following:
- Fish early in the morning while the water temperature is cooler.
- Carry a pocket thermometer to monitor the water temperature.
- If the water temperature is at or above 65 degrees, consider keeping what you catch within the regulations. If the temperature is 70 degrees or higher, do not attempt to catch and release fish.
As water temperature increases, using the proper techniques to catch and release a fish become increasingly more important to help ensure the fish has a chance to survive, WGFD says:
- Play and land fish as rapidly as possible to reduce exhaustion stress.
- Keep the fish in the water as much as possible.
- Do not squeeze the fish or place fingers in the gills.
- Remove the hook gently. If hooked deeply, cut the leader.
- Flies and lures are recommended whenever many fish are being caught and released.
- Barbless hooks allow easier hook removal.
- If a fish is exhausted and cannot hold itself upright, and if regulations allow, consider having it for supper because the fish has a poor chance of surviving.
“These are not new regulations, just recommendations to assist with the conservation of the fishery resource,” Osterland said. “If water temperatures are too high, consider escaping the heat with a trip to another top-notch high country fishery where it’s cooler.”
