“We’ve seen a very marked reduction in the overall abundance of invertebrates in springs following warmer winters,” Ormerod said. “We’re still trying to nail exactly what the mechanism is,” he added. “We know something is going on but we don’t exactly know what process is driving it.”

Ormerod’s studies link a 50 percent reduction in salmon and trout populations in the River Wye over the past 20 years to climate warming, but in that case, “reductions are most pronounced immediately following hot, dry summers.”

The second paragraph isn't surprising but the first one is. It's likely to affect fish growth. If it applies to other waters it could become significant for other fish species, both game and coarse.
