Fish kills because of the heat

Posted:
BLACK HAWK COUNTY (KWWL) -

Fish kill reports are starting to pop up across the state of Iowa. Lori Eberhard, George Wyth park manager, has already had one fish kill reported at Brinker Lake and it's no surprise why.

"Some of these fish are cool water fish so those are really starting to show the stress. Brinker Lake, the fisherman that reported it said his depth finder measured the temperature of water at 89 degrees," said Lori Eberhard.

According to experts, cool water fish like sturgeon, pike, yellow perch and walleye are most susceptible to the heat. But even fish able to tolerate warm water are showing stress and the drought may have something to do with it.

"In some areas if you only have just a few feet of water, it's probably close to 90 degrees through the whole part of it. They don't have a deep pocket to go to. Any fish are going to start showing stress," said Eberhard.

Unfortunately, little can be done to save these fish.

"If it's weather related there really isn't a lot we can do about it because we just need cooler weather. That's the only thing we can do. We don't have enough ice to throw in the lakes," said Eberhard.

But if you're a fisherman, not all hope is lost.

"You know it's not fun being out in 100 degree weather, but there's fish biting out there. We got guys that are catching catfish prevalent. We had a couple thirteen and fifteen pounders last month," said Charlie Ahrens of Hank's Live Bait & Tackle.

According to Ahrens, the best time to fish is early in the morning before the sun is high in the sky.
