High temperatures sooner than usual this summer may pose a threat for early fish kill. Temperatures were at the century mark in much of the state for several days this past week. The extreme heat works to quickly warm up the waters in the lakes and reservoirs and fish may become heat-wave victims.
Department of Natural Resources spokesman Brett Witt says fish kill is typical during the summer months, but it may occur earlier than usual this year.
Given the fact that we’re looking at such high temperatures so early in the summer, the possibility of fish kill obviously goes up. Typically we see that later in the summer, but we may see that coming on earlier this year.
Witt says it happens when the water warms up and fish go deeper to find cooler temperatures.
The water on the top, basically has more oxygen, but it’s hotter and the fish don’t like that. They go down where it’s cooler, where it has less oxygen, and so you end up with stress on these particular fish and you end up with increased mortality, and that could be from several dozen fish to several hundred.
The National Weather Service says there’s a possibility much of the state could record 90 or higher every day of the month of June.
