Experiments have shown that planting fishproperly is equally as important as rearing fish. Efforts are being made toplant the different species when the natural food in the streams and lake is atits peak. For years the native cutthroats have been planted in the fall afterevery effort had been made to rear them to a suitable size before results attended this method and it was demonstrated that,especially with the natives which are planted in the higher elevations, it wasnot the size of the fingerlings when planted, but the time of the year which wasthe big factor in their development.
