Kamlnnps Rainhnw Trmit 



Kamloops trout arc a strain of rainbow trout that originated in the north arm of Kootenay Lake 

 in British Columbia. The broodstock for this strain are from trout that spawned in the Duncan 

 River ftom Kootenay Lake. The kamloops has been planted by FWP in several western Montana 

 lakes. 



The kamloops spawn from mid March through June, on average, but discharge and temperature 

 may shift the timing of the spawning. The kamloops is long-lived and is known for becoming 

 very large (over 20 pounds). It obtains the large sizes by feeding heavily on fish (primarily 

 kokanee) once it reaches a size of 12 inches. Because of the kamloops ability to reach large sizes 

 they highly sought after game fish, but its catch rate is very low (.02 fish per hour on average in 

 some lakes). Kamloops are not readily available at this time.

Kokanee salmon are the landlocked form of Pacific sockeye salmon. Kokanee are widely planted 

 in Montana and the Pacific Northwest. The broodstock for northwest Montana originated through 

 Flathead Lake fi'om Canada. Currently eggs are taken from wild kokanee in several northwest 

 Montana lakes. 



Kokanee goi^ally spawn in the tributaries of their home lake but often times will use spring areas 

 in the late. Kokanee dig shallow owning nests or redds in small gravel. Salmon die after they 

 spawn. This salmon appears to have limited reproduction in Middle Thompson Lake and Crystal 

 Lake, but most likely will not reproduce successfully in other TCL lakes because they are closed 

 basins and have limited spring infiuence. Kokanee generally feed primarily on zooplankton and 

 on aquatic insects when they are abundant. The life expectancy of kokanee is fairly short, most 

 spawn and die in three years, some will live to five years. The average kokanee in northwest 

 Montana is 10"-12" although some kokanee in the Thompsons will exceed 20 inches. Kokanee 

 are catchable by a number of methods and are prized by anglers for fighting and eating qualities. 



Brown Trout 



Brown trout are widely established in the lower Clark Fork Drainage. They have been planted 

 in the Thompson Lakes and upper Thompson River but do not appear to have established self- 

 sustaining populations. Brown trout spawn in the fall in streams. 



Brown trout eat insects when small but become very predacious when large. They can grow to 

 10-20 pounds. Most anglers find them difficult to catch.
