Possum Kingdom Fishery bounces back

ATHENS—Possum Kingdom Reservoir appears to have largely recovered from the effects of an outbreak of golden alga that struck the lake in spring 2010, according to the latest fish surveys conducted by Texas Parks and Wildlife Department (TPWD) fisheries biologists.

“Largemouth bass came through the golden alga outbreak fairly well,” said biologist Robert Mauk. “The largemouth bass electrofishing catch rate was 53.5 fish per hour, which is slightly up from 49.0 per hour in the 2008 survey. Most bass were below the 16-inch legal size limit and were found throughout the reservoir. Stocking has not occurred since 2005, so the smaller bass were all naturally produced despite the occasional golden alga problems.”

The majority of the legal bass, including four over 20 inches, were found on the main lake from Caddo Creek to the dam.

Mauk said there is an abundance of prey species in the reservoir, and the predator species such as largemouth bass appear to be taking advantage of it. “All bass were extremely fat, probably from feeding on the abundant gizzard shad population,” Mauk said. “The gizzard shad catch rate of 306.5 per hour was above the historical average of 287.9 per hour, and most shad were four to five inches in length. Bluegill numbers were down compared to recent surveys while all other species of sunfish catch rates greatly increased.”
