FAIRBANKS- Hundreds of dead fishing are showing up in shallow water along the shore of a popular interior Alaska lake and wildlife officials say the region's long winter likely is the reason.
   
Tom Taube of the Alaska Department of Fish and Game says the magnitude of the die-off of rainbow trout and arctic char at Quartz Lake wasn't apparent until ice went out last weekend.
   
Quartz Lake is 80 miles south of Fairbanks..
   
Taube tells the Fairbanks Daily News-Miner (http://bit.ly/10QehB8) that a "perfect storm of conditions" including lingering thick ice likely led to the die-off.
   
He says light penetrates the ice, resulting in plankton growth that produces an oxygen deficit at night. The light also speeds decomposition of last year's vegetation, which saps oxygen.
