145.->OTES ON THE CULTIVATION OF FISH-OTOSTEY AMERICAN— 



IN FKANCE.* 



Brook trout. — Mr. Despres has written from ISTauteuil-en-Vallee : 

 " I Lave ouly a small number of fry [of Salmo fontinaUs] from the- 

 eggs which you sent me last year, about 200. These specimens, al- 

 though kept under circumstances only half satisfactory, are in very goodl 

 condition, having- attained on the average from 10 to 12 centimeters- 

 [about 4 inches] in length. I think they would have reached a greater 

 size if thej' had been furnished with regular food independent of what 

 they found in their basin. I intend to give this to them in the future."' 

 [Bulletin, March, 1883, p. 1G5.] 



California salmon. — In returning thanks for the salmon eggs, 

 which had been sent him, Mr. Kathelot has written from Grand-Mont- 

 rouge : 



" The eggs of the Salmo quinnat Avhich you sent me in December, 1881^ 

 came very well. The first, which I i^laced in a basin in the open air, 

 are large enough ; they have attained a length of 22 centimeters [about 

 8 inches]. Those which I left in my laboratory and which I placed some- 

 montlis after in the same pond are smaller, not having enjoyed while- 

 young the same food as the first, which, in addition to the horse-flesh, 

 which I give them, found in that stagnant water little worms and other- 

 animalcules which increased their growth. They have endured during- 

 the hot weather a temperature of 22° C. [71o.6 F.]. They live for th& 

 present on very good terms with the blays, gudgeons, barbels, and craw- 

 fish. Towards the last of October a quantity of poplar and other leaves, 

 having- fallen into the pond, the water became much colored. Seeing 

 that mj fish would not eat, and not wishing to pursue the experiment 

 further, I was obliged to proceed to clean out the basin. I give these 

 details in order to show that the iSalmo quinnat does not require a par- 

 ticular kind of water." [Bulletin, March, 1883, p. 165.] 



The control of waters. — Mr. A. Leroy read from a note on the 

 depopulation and restocking of the rivers of France. 



Mr. Eaveret-Wattel i^ointed out, on the occasion of this communica- 

 tion, the considerable damage done in the rivers by the inadequacy of 

 certain provisions of the legislation in regard to fish, by poaching, and,
