464 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



contrary to the views of most fish-culturists, natural spawn- 

 i\^g is preferable to artificial in every respect. 



Mr. Dykeman, in a paper on the impregnation of trout eggs, 

 gave the result of experiences at his establishment at Ship- 

 pensburg, Pennsylvania. Mr. Charles Bell read a paper on 

 the fecundation of fish, in which he denies that the sperma- 

 tozoa are distinguishable as independent organisms, instead 

 of being simply free moving cells. A communication was 

 presented by Mr. George Shepard Page upon fish -culture 

 abroad, embracing the results of inquiries made by him, 

 through the State Department, in China and Japan, in regard 

 to the practice in those countries. From this it would appear 

 that artificial culture, as we understand it, is unknown in 

 those regions, efibrts there being limited to the gathering of 

 the spawn, as naturally impregnated, and hatching them out ; 

 and also to keeping fish in reservoirs, where they can spawn, 

 or where they can receive considerable accession of growth. 

 Mr. A. P. Rockwood enumerates the native fish of Utah, in- 

 cluding among them the lake trout, which sometimes weighs 

 twenty-five pounds, the brook trout, weighing from one to 

 three pounds, the sucker^ chub, and a fish something like the 

 cat-fish. 



In addition to the papers actually presented at the meet- 

 ing, the report embraces an extract from a letter of Professor 

 Baird, United States Fish Commissioner, addressed to the 

 Committee on Approj)riations of Congress, on the subject of 

 fish propagation. 



TAKING CALIFOKNIA SALMON AVITH THE HOOK. 



The question recently raised as to the propriety of intro- 

 ducing the California salmon into the Eastern United States, 

 in view of the alleged impossibility of taking it by the hook, 

 has been effectually set at rest by a communication from 

 Livingston Stone, Esq., in charge of the United States sal- 

 mon-hatching establishment on the Sacramento. This gentle- 

 man reports, under date of August 2, that salmon were then 

 being taken in great numbers in the M'Cloud River, princi- 

 pally grilse, the bait used being salmon spawn. He does 

 not state, however, whether any have been taken with the 

 fly, although it is probable that if they will take one kind of 

 bait, they will not refuse the other.
