ANCHORAGE, Alaska (Reuters) – Alaska’s summer heat wave has been pleasant for humans but punitive for some of its fish.

Overheated water has been blamed for large die-offs of hatchery trout and salmon stocks in at least two parts of the state as hot, dry weather has set in, according to the Alaska Department of Fish and Game.

Hundreds of grayling and rainbow trout died in June after being placed in a Fairbanks lake, the department reported. An unusually cold spring caused lake ice to linger much longer than normal, before the water quickly became too warm, department biologist April Behr said.

Surface temperatures in the lake rose to about 76 degrees Fahrenheit (24 degrees Celsius), she said. The precise number of dead fish was not yet known. “We picked up several hundred,” she said.

A similar incident occurred in Read more…

DEAD and bloated catfish are washing up on the banks of the Brisbane River in their thousands, leaving scientists searching for an explanation.

DEAD and bloated catfish are washing up on the banks of the Brisbane River in their thousands, leaving scientists searching for an explanation.

SeqWater officers were seen scouring the banks of the river just outside the centre of Lowood yesterday, where scaly bodies were scattered along rocky sections of the bank or bobbing belly-up in the steady current.

It is believed hundreds of fish were found dead last week and more were counted yesterday – totalling in the thousands.

The dead fish were found as far upstream as the Lockyer Creek.

Only catfish seem to have been affected, leading to speculation that a virus may be sweeping through fish populations in the river.

Department of Environment and Heritage Protection executive director Andrew Connor said there would be no explanation for the fish Read more…

Workers with Game and Fish and ADEQ head out on the Arkansas River to try and determine the reason for Tuesday’s fish kill.
