We will first deal with those that are native to this state, cutthroat or black- Montana whitefish, and included in these are spotted trout, Dolly Varden, and the Montana grayling. NATIVE The native cutthroat or black-spotted trout were first mentioned in history when the Lewis and Clark expedition went through Montana. They are a member of the Salmon family and were found in all of the drainage areas of Montana. They spawn in the spring and early summer, seeking the shallow waters of the smaller creeks or lakes where gravel bars are in evidence. These trout vary greatly in the sizes at which they reach ma- turity, the controlling factors being the size of the body of water they inhabit and the abundance of the food supply. In certain lakes where food is abundant they have been known to reach a weight of 17 pounds, while in many small moun- tain streams they have reached maturity at 6 or 7 inches and are often spoken of as brook trout under the impression that they are a species dif- ferent from the larger ones. In gameness they are second only to the rainbow and in feeding habits are similar to most all trout. They are opportunists and when hungry will take anything that prom- ises to be food, even fish of their own species. DOLLY VARDEN This interesting member of the charr family is found in the streams and lakes of Montana, Idaho, Washington, Oregon and California, and northward in coastal streams to the Aleutian Islands. It is found only in the Pacific drainage. It is known under other local names such as the bulltrout and charr. Its size is also governed by environment and specimens only 12 inches long might have the same age maturity as some speci- mens
