On Thursday, May 10, youngsters from Clearwater Preschool once again helped staff from Clearwater Trout Hatchery stock Dutch Lake with trout.
“We stocked 1,500 Dragon 2N rainbow trout and 5,000 kokanee into Dutch Lake this year,” reported hatchery manager Mark Green.
Green said there were 2,500 2N kokanee with an adipose fin clipped off and 2,500 3N kokanee with no clip.
“The Region 3 biologist wants to see if the 2N kokanee get bigger, quicker and enter the fishery at a larger size then the 3N kokanee,” he explained.

Hatchery staff can tell the difference between the two types of fish by clipping different fins off. This year 2N kokanee had the adipose (AD) clip and 3N had no clip (NC). Last year the clips were right vent (RV) for 2N kokanee and left vent (LV) for 3N kokanee.
The figures 2N and 3N refer to the number of sets of DNA the fish have - 2N being normal and 3N having an extra set and therefore sterile.
