Kamloops trout are the same as regular rainbow trout. See the following from a artical from Ron Newman.
[font "Verdana, Arial, Helvetica, sans-serif"][size 2]Then in 1931 a Dr. Mottley began to study the Kamloops Trout. He discovered that the differences in Salmo Gairdneri and Salmo Kamloops were due to environmental conditions rather than genetic differences. He had found that the spawning streams in south central British Columbia were about 9 degrees Fahrenheit cooler than most spawning streams around the world. [/size][/font]
[font "Verdana, Arial, Helvetica, sans-serif"][size 2]He conducted an experiment in which Kamloops Trout eggs from the same fish were hatched and raised in two different environments. One set of eggs were hatched and raised at the normal stream temperatures around Kamloops and the second set were hatched and raised in waters 9 degrees warmer than would normally be expected in the local spawning streams. Those fish raised in the warmer water did not develop the extra scale rows and other physical differences of Salmo Kamloops. He had raised both types of fish from the same batch of eggs and thus proven that Salmo Gairdneri and Salmo Kamloops were indeed the same fish. The differences were environmental rather than genetic.
