Extreme winters impact fish negatively
Date:2/15/2013

that models of how water moves and what fish populations look like should also take winter conditions into consideration.

Today most models focus on the ice-free period. A third conclusion is that in order to be able to manage streams and rivers in a long-term sustainable manner, we need to pay attention to future changes in climate when we, for example, design restoration and conservation measures.

"The predictions made about what the winter climate will be like in the future say that there will be more back and forth between thaw and frost, entailing more unstable ice conditions, more rain, and flooding, and ultimately perhaps more challenges to the survival of fish in many waterways," says Christer Nilsson.
