"I haven't seen anything like that before. I've seen bass with black spots, but I'd never seen an albino one," Moore told the wildlife agency.
Alex McCrickard, the agency's aquatic education coordinator, said the fish is not an albino, but has a related condition.
"Golden largemouth bass are extremely rare and most anglers have never seen them, let alone heard of them before," McCrickard said.
"The fish is a product of a genetic mutation that alters the skin pigments called xanthism. Yellow pigmentation dominates in xanthism, as you can see in Moore's golden largemouth."
Moore said he was returned the fish to the river after he measured it and snapped a few photos.
