TD said that without the environment and groceries, they are just another trout ........ Isn't that what Dr. Mottley said?
Again, I am missing where TD said this. To be honest, it doesn't make much sense. I do agree without groceries there would be NO trout, but I read in that article (which is just one persons writing and really dated) that KAMLOOPS do adapt to their environment.
Here is the rest of your attachment:
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.
In subsequent work, Dr. Mottley also found a few other quirks of the Kamloops Trout that are of interest to the angler. The cool spring time and hot summers played a part in the development of these fish. Water temperatures remained cool, like alpine streams, during the critical phases of development, which are the egg, alevin and fry. This cool water was responsible for the physical differences in the fish. During the hot summer the water warmed sufficiently to provide vast quantities of food for the growing trout. This helped to explain the strength, stamina and size differences. Mottley even found that the physical characteristics of the Kamloops Trout changed with the elevation of the lake in which they were raised. Also, attempts to stock Kamloops Trout in other locations have all met with failure unless the environmental conditions are virtually the same as in southern British Columbia.
Shortly after Dr. Mottleys work was confirmed the scientific community removed Salmo Kamloops from its official registry of fish species. Officially the Kamloops Trout ceased to exist. And yet those fish with that extra strength and stamina, those extra rows of scales, the fin and camouflage spot differences and larger size are still in the lakes of south central British Columbia. So in answer to our original question, "YES" there is a Kamloops Trout that is distinct and different from other Rainbow Trout in terms of its fighting ability and physical characteristics. But "NO" it is not genetically different from the more familiar Rainbow Trout. It is a product of the local environment and cannot be exported.
Anyway, enough of that, like the old saying you can wish in one hand and --------in the other .....so, on...LOL
