McCloud River Rainbow Trout 



tends from early February to May. A curious change in the season 

 has occurred with those cultivated in the E:ist. In Colorado the 

 season is from May to July, while at Wytheville it extends from 

 early in November to the end of February. 



The males are good breeders at 2 years old, but the females 

 rarely produce eggs until the third season. 



The number of eggs produced depends upon the age and 

 size of the fish. The maximum from 3-year-old fish, weighing 

 | to i pounds, is 500 to 800 eggs; from 6-year-old fish, weigh- 

 ing 2 to 4 pounds, it is 2,soo to 3,000 eggs. 



The eggs vary in size from 4^- to 5 eggs to the linear inrh, 

 the larger fish usually producing the larger eggs. 



All that has been said regarding the game qualities of the 

 typical rainbow trout (Salmo iridcus) can be said of the rainbow 

 trout of McCloud River. It may lack a little in the wild gameness 

 of typical irideus, but that is made good by its larger size. 



There is, however, no comparison between the rainbow in 

 its native California mountain streams and those introduced into 

 eastern waters, where the warmer temperature has enervated 

 them, and where they have grown large and fat and sluggish. 

 In the cold waters of Colorado, however, they have lost none of 

 their wild nature and superb game qualities. 



Head 4; depth 3!; eye 5; D. n; A. n; scales 20 to 24-14*,- 

 20, about 65 before the dorsal. Body comparatively short and
