Lake Normanís crappie fishery has improved over the past half-dozen years, with fishermen like Chris Nichols reporting greater numbers of fish, as well as the quality fish theyíve caught in the past.
Thatís when theyíll examine fish for weight, length and age and determine by the number of fish they catch in their sample and the health of fish whether or not a change has taken place.
Lawrence Dorsey of Albemarle, a Commission biologist whose territory includes most of the lakeís southeastern shoreline, said that short-term improvements in a fishery can be caused by any number of factors, but a series of excellent spawns and year-classes of fish is usually one of the keys.
"Itís very difficult to isolate one thing that causes something a change in a fishery," Dorsey said. "You can examine a number of different factors; weíve tried to do that. Weíve measured things like water flow through a reservoir to see if thereís any bearing. Itís just hard to say that one thing caused any change."
Dorsey said that anecdotal reports from fishermen at Lake Wylie, which is two impoundments downstream from Lake Norman, about a similar change in the crappie fishery. "You heard about Wylie that nobody caught many fish, but the ones that caught were nice ones," he said. "Now, weíre hearing that fishermen are catching much better numbers of fish. Maybe itís the same thing.
