Iowa’s up and down temperatures have caused some problems for the love life of the state’s fish.D-N-R spokesman Kevin Baskins says alternating warm and cold days this spring have made it tough for frolicking fish.The increase in water temperature in Iowa’s lakes and rivers is the signal to fish such as the crappies and bluegills to start spawning. Baskins says Mother Nature’s been sending mixed signals this spring.It’s been cooler than normal, and once it does warm up, it cools off again. Baskins says the warm ups get the fish fooled into starting to spawn, and then they’re stressed when it cools down. Baskins says the spawn stress is believed to be the cause of a fish kill earlier this month in southern Iowa.
