Illinois Department of Natural Resources fisheries biologists are pondering whether to increase creel limits on crappies at Lake Shelbyville.
Mike Mounce, biologist at the 11,000-acre reservoir, said the move is being considered that would let anglers keep more crappies, including a few under the current length limit of 10 inches. No rule change would go into effect before at least April 1. The current rules are 10 fish daily, with each one at least 10 inches or longer.
Mounce said a review of current rules came after complaints over the past few years from anglers who said they were not catching as many legal crappie at the lake as they had in past years.
Earlier surveys indicated the growth rate for white crappies was on target. Fish reached the 10-inch limit in about 2½ years, he said. However, after the complaints Mounce used other more accurate techniques which revealed the fish were taking about four years to reach the legal limit.
"That's about six months to a year longer than what I'd like to see," Mounce said.
In addition, an abundant number of black crappies, which are far more numerous than the white crappie, are growing so slowly that most don't reach the 10-inch mark, he said. For example, surveys found about 34 percent of the white crappies were over 10 inches but only 1 percent of the black crappies reached 10 inches and it was taking six years for them to reach that length.
A rule change would allow anglers to harvest more fish from the population and reduce food competition among the crappies, Mounce said.
Mounce has visited with lake guides and angling clubs for input on the proposal. He does not know what the new rules will be. The goal is to fashion a regulation to achieve a faster growth rate and allow anglers to enjoy the tasty food crappies provide.
Fine-tuning a crappie population is not easy, Mounce said.
"This is a problem with crappies. They have large population shifts. One year the regulation might be appropriate and the next year it's not," he said.
IDNR biologists also are taking a look at a larger-than-normal spring die-off of muskies in the Kaskaskia River below the Lake Shelbyville Dam.
The cause is unclear, but speculation centers on unusual weather in Central Illinois during the spring. Water temperatures hovered at the spawning temperature for the fish for longer than usual. That fact might have caused more stress on the fish than they experience during most years. More stress weakens the fish and makes them more vulnerable to diseases.
Mild weather earlier in the season also meant fishing pressure in the spillway was intense. More released fish may be dying from injuries caused by poor release techniques. The spillway, which holds the current state muskie record at 38½ pounds, is popular.
"This is not an unusual occurrence. We generally lose some after the spawning season," Mounce said. "But, this is exceptionally heavy this year."
