In the lake environment, recognition of life history stages, parr, smolt, and adult, presents some difficulties particularly as dead fish tend to revert to a more parr-like appearance. It was important for this study to recognize, if at all Table 6—Mean condition factors (K)' of salmon at various life stages in Lake Gallienne and Cross key Lake Galienne (July-Aug.)
