Wyoming Game and Fish Advises Anglers to Modify Summer Fishing Habits to Protect Trout

The Wyoming Game and Fish Department is advising anglers to adjust their fishing habits during the hottest part of summer to help protect fish, particularly trout, from the harmful effects of warm water temperatures.

“It’s that time of year when water temperatures are highest. Warmer surface temperatures have the potential to be lethal to trout,” Alan Osterland, Game and Fish Fish Division Chief, said to Sheridan Media. “Warm water also holds less oxygen, which can stress not only trout but also all fish.”

Warmer water holds less oxygen, which puts stress on fish and reduces their chances of surviving after being caught and released. Trout are especially vulnerable to prolonged exposure to 75°F+ water, with temperatures above 80°F being lethal.

“As water temperatures increase, anglers should monitor water temps while fishing. When water temperatures hit 70 degrees, we recommend anglers stop catching and releasing fish… Practice self-restraint to help fish survive.” Osterland said.

Anglers are advised to fish early in the day, as water is cooler. You can use a pocket thermometer to check the water temperature. If water is 65°F or above, consider keeping fish you catch within regulations. It’s better to stop catch-and-release if water temperature hits 70°F.

The best practice for catch-and-release would be landing fish quickly to reduce stress. Try keeping fish in the water. Avoid squeezing or touching the gills. Remove hooks gently, cutting the line if the hook is deep. Use barbless hooks and flies or lures for easier handling. If a fish is too weak to survive release and rules permit, consider harvesting it.

Using the proper techniques to catch and release a fish ensures its chance to survive.

“These are not new regulations, just recommendations to assist with the conservation of the fishery resource… If water temperatures are too high, consider escaping the heat with a trip to another top-notch, high-country fishery where it’s cooler.” Osterland concluded.
