420 BULLETIN OF THE UNITED STATES FISH COMMISSION. 



tlie time of sexual maturity this fish had not proved hardy, and because 

 they also thought that its meat did not have as delicate a flavor as that 

 of other species of salmon. Dr. Staudinger stated that in the region of 

 the Danube, where the migratory salmon {Sahno solar) is not found, 

 there were many who desired to see the California salmon introduced. 



No special desire was expressed for American lake trout, but Dr. 

 Staudinger suggested, and was in this unanimously supported by the 

 conference, that, considering the great value of the American whiteflsh 

 {Coregonus albus), and the favorable results of hatching experiments, 

 more eggs of this fish should be imported, particularly with the view 

 to continuing the experiments which had so far proved successful, and 

 which could be called thoroughly successful only if continued on a large 

 scale. It is desirable to well stock such alpine lakes as the Walchen 

 Lake, Ammer I^ake, &c., with this species. 



As regards the American brook trout {Salmo [Salvelhms] fontinalis) 

 Yon Belir stated that quite a quantity of eggs of this fish had already 

 been produced in Germany, and that he would see to their proper dis- 

 tribution. Dr. Staudinger thought that the Salvelinus fo7itinalis would 

 certainly flourish in the brooks of the alj^ine and subalpine regions. 

 In these regions no trout are found, and for this very reason people 

 took great interest in seeing the Salvelinus fontmalis acclimatized. For 

 this purpose Dr. Staudinger, supported by Mr. Schuster, considered it 

 very desirable to continue the importation of the eggs of this fish from 

 America. The conference approved and recommended that the eggs 

 should be furnished, especially to those hatching establishments where 

 successful attempts had already been made to raise the Salvelinus fon- 

 tinalis. 



Messrs. Haack and Schuster warmly advocated the importation of 

 eggs of the rainbow trout {SaJmo irideus). Mr. Haack considered this 

 species of fish the most valuable and iiromising of all the fish intro- 

 duced from America. Mr, Schuster also stated that the eggs and fish 

 of this species are particularly valuable, although he was not quite so 

 enthusiastic on the subject as Mr. Haack. The conference recom- 

 mended to acquire as many eggs of the rainbow trout as possible, and 

 to carefully distribute them. 



As regards the American landlocked salmon it seemed to be the i)re- 

 vailing opinion that for the present no more eggs should be asked for. 

 It was thought that this fish would ofler no greater advantage than our 

 own German lake-trout, and it was not deemed desirable to mix too 

 many species of closely related fish. 



The importation of eggs of Trutta carpio from Garda Lake, in Italy, 

 did not meet with favor. On motion of Mr. Staudinger, however, 

 20.000 to 30,000 more eggs may be obtained for Ammer Lake, which 

 seems well adapted to it.
