504 NATURAL HISTORY OF AQUATIC ANIMALS. 



hi Germany and in Austria it has been found that the Saibling is one of the- most expensive fish 

 to propagate artificially, on account of its food. The ordinary size of the Saibling is from eleven 

 to twelve inches, and its weight from one-half to one pound. In the highest lakes they are, as h;is 

 been mentioned, smaller, while when they are moved from such lakes into those that are deeper 

 they increase rapidly in size. In the Saltzberg lakes, where they are taken upon certain spawning 

 grounds from November to January, it takes about five of them to make a pound, bnt large speci 

 meiis of three to twelve pounds are taken in August and September. In the Lake of Zug, which, 

 according to Hoch, yields more Saibliug than any other lake in Switzerland, it takes five or six, 

 often eight or nine, to make a pound. In the Lake of Geneva they are often taken weighing 

 twenty to twenty -four pounds. Herr Hoch himself saw one weighing seventeen pounds.'' 



To this may be added a paragraph from Millet's "La Culture de 1'Eau." "Itis very voracious, 

 and, like the Trout, very swift and active in its movements. It habitually feeds upon small fishes, 

 upon crustaceans, upon mollusks and insects, and in two or three years, under favorable circum- 

 stances, attains the length of fifteen to twenty inches. Its flesh is very delicate and savory, and 

 it is preferred abont Lake Leman to any other fish." 



CULTURE. The Salbling has been propagated by German fish-culturists for a period of ten 

 years or more, and thrives magnificently in captivity. The hatchery at Oussee, in Germany, pro 

 tluccs yearly three or four hundred thousand of artificially-brooded Saibling, and plants them in the 

 neighboring lakes. In the tanks at the late International Fishery Exhibition in Berlin were ex- 

 hibited many superb specimens of this fish, some of them over two feet in length, and one of these 

 was sent to the National Museum by Herr von Behr, president of the Deutscher Fischerei Verein. 

 It is as large as the famous Rangely Lake Trout caught by Mr. George Shepard Page, which 

 everybody has seen at Blackford's in Fulton Market. 



In selecting a place in which to deposit the saibling eggs just received, the Commissioner of 

 Fisheries has endeavored to find a lake as similar as possible in depth and temperature to the 

 larger Swiss lakes, and he has, therefore, sent them to Lake Winuipiseogee, N. H. *Here the 

 whole sixty thousand were planted, with the hope that by placing so large a number together in 

 a lake of moderate size the experiment of introduction may be a success. It is a question of some 

 interest which of the many European names of this fish should be adopted in the United States 

 should the experiment of acclimation be a success. 



It would seem most appropriate that, since the fish acquires its greatest perfection in Germany, 

 the German name should be adopted, particularly since the German fish-culturists, who have so 

 kindly made this gift to the people of the United States, will regard as a compliment the adoption 

 of the German name of one of the favorite fishes of Germany. 



166. THE DOLLY VARDEN TROUT SALVELINUS MALMA. 

 By DAVID S. JORDAN. 



This species is known in the mountains as "Lake Trout," "Bull Trout," "Speckled Trout," and 

 "Red-spotted Trout." In the ocean, where it is found iu large numbers, it is the "Salmon Trout." 

 In the Sacramento the name "Dolly Varden" was given to it by the landlady at a hotel, and this 

 name it still retains in that region. As none of the other names are distinctive, this one may well 

 be adopted. In Siberia it was formerly known as the "Malma" or "Golet," The Indian name 

 "Chewagh " is ascribed to it in British Columbia. In size this species reaches a weight of fourteen 

 pounds. The largest I have seen weighed twelve pounds, which weight is not uncommon in the
