RE"[#800000][size 2]I understand that a Red Band Trout is a whole other species?[/size][/#800000] "
The rainbow trout species (Onchorhynchus mykiss) has 4 main subspecies.
1. The coastal rainbow trout (O.m.irideus)
2. The redband trout.
3. The Kern river basin trout, including the golden trout (O.m.aguabonita) and others.
4. Several closely related Mexican subspecies.
The redband trout is further divided into 3 subgroupings.
1. The redband trout of the Northern Great basin, plus the Klamath lake basin of Oregon. (O.m.newberryi)
2. The redband trout of the Northern Sacramento river basin. (O.m.stonei)
3. The redband trout of the mid and upper Columbia and Fraser river basins which includes the Kamloops trout. (O.m.gairdneri)
The redbands are not considered a separate species, and suprisingly a "kamloops" is a redband trout!
Both Coastal rainbows and redbands have Anadromous forms. (or steelhead if you will)
The "Kamloops" trout is a variety of redband that is adapted for life in large lakes of the upper Columbia and Fraser river basins. These lake adapted trout often eat kokanees and reach sexual maturity at a later age. 4-6 years as opposed to 2-3 yrs.
[#800000][size 2]If you move Kamploops from BC and the Idaho panhandle, like TubeDude said, they cease to be Kamloops? (see attached).[/size][/#800000]
No.
Most Kamloops are not known for extraordinary size. However one life history strain from Kootenay lake (called the Gerrard strain) is known to achieve greater size under ideal conditions. These were the fish put into Lake Pend Orielle in Idaho and were initially huge in size until the kokes were eaten out. Generally though, the kamloops trout will grow to the size the available groceries allow, just like other strains.
Clear as mud?
