a large number belong to this same genus Salmo ; some are 

 marine, others fresh-water (Figs. 297 and 298). One of the 



most widely distributed is 

 the black-spotted trout of 

 northern Europe, Asia, 

 and America west of the 

 Mississippi Valley. But 

 no trout is equal to the 

 brook trout, Salve linns 

 foniinalis, for gaminess ; 

 in England it is known as 

 the charr, and is thus dis- 

 tinguished from the mem- 

 bers of the genus Salmo. 

 It frequents clear, cold 

 mountain streams and 

 lakes in the northern portions of both continents, except in the 

 Rocky Mountain region. In the United States it occurs only east 

 of the Mississippi, from northern Georgia northward. Unfortu- 

 nately it is fast disappearing ; it is the favorite game fish of 

 America, and sought after by every lover of true sport. 



The North Atlantic supplies a large number of excellent food 

 fishes, such as the bluefish, found off our eastern coast ; the 

 pompano, one of our choicest Southern fishes ; the mackerel, 

 which moves in large schools and is taken by seines or by lines; 

 the Spanish mackerel, which is found along our Southern coast; 

 the swordfish, widely distributed in temperate waters ; the red 

 snapper of Florida, one of our best Southern fishes ; the striped 



Salmo fario. Caudal end of vertebral
