Biological observations
Biologists don’t see a problem with the trout population in Calcasieu Lake. They said that anglers might catch fewer specks because fish simply don’t bite occasionally or they move to find better food, temperatures or water conditions.
“The speckled trout population in the Calcasieu Estuary is healthy,” said Mike Harbison, a biologist with the Louisiana Department of Wildlife and Fisheries in Lake Charles. “I don’t see a biological need to change the limit. We are finding fish in our sampling. If something is not broken, why fix it?”
Trout spawn from April through September with the peak in June, Harbison said. A speck reaches sexual maturity after one year. One large trout can produce 1.65 million eggs in a spawning season.
A trout may live 13 years, but most die before they live one year. More than 90 percent of trout die before they live four years. About four percent reach 25 inches long. One percent reaches 26 inches. Natural mortality from predators or other environmental factors take 66 percent of the trout regardless of fishing pressure. If the state banned fishing entirely, that percentage will not change, Harbison said.
“If we dropped the limit to 15 fish per day, we’ll only save about 14 percent of the fish caught now,” Harbison said. “If we go down to 10 fish per day, we’ll save about 29 percent of the fish now caught and kept. To make any significant changes, we’ll have to go to eight fish per day or less.”
