Warm Temperatures Increase Stress on Fish

This is good advice from ODFW

From Oregon Department of Fish and Wildlife

SALEM, Ore. -- With summer temperatures heating up throughout the state, the Oregon Department of Fish and Wildlife is asking anglers to take special care when catching and releasing fish.

“Warm water temperatures, especially above 70 degrees, can be very hard on cool water fish such as trout, steelhead and salmon,” said Charlie Corrarino, ODFW Conservation and Recovery Program manager.

Warm water does not hold as much oxygen as cooler water. This means fish are getting less oxygen while they are being caught, and take longer to recover once they are released.

“A lot of fish simply stop biting when the water gets too warm,” Corrarino said. “And many anglers will voluntary limit their fishing when air and water temperatures are high in order protect fish populations.”
However, Corrarino adds, anglers can still safely enjoy trout, steelhead and salmon fishing it they follow a few precautions.

•Fish early in the mornings when water temperatures are lower.

•Fish in lakes and reservoirs with deep waters that provide a cooler refuge for fish.

•Use barbless hooks, land fish quickly and keep them in the water as much as possible in order to minimize stress.

•Shift your fishing efforts to higher elevation mountain lakes and streams where water temperatures often remain cool.

“Once cool fall weather arrives, water temperatures will drop and trout will begin actively feeding again. ODFW also will resume stocking trout in many lakes and reservoirs,” he said. “In fact, fall can offer some of the best fishing of the year.”
