Fisheries research is being conducted on several species in North Idaho, including studies on rainbow trout that may help fish mangers adjust stocking schedules to give anglers the most bang for their buck.
Surveys have helped biologists understand that Hauser Lake is becoming less productive for trout as it ages.
The percentage of stocked trout caught by anglers ranges up to 80 percent in Kelso Lake.
Kelso’s extremely high exploitation rate indicates that fish managers likely can justify the expense of increasing the number of hatchery fish stocked in the lake each year.
