402 PISCICULTURE. 



France, who seeing their occupation nearly gone by the 

 rapid decrease of fish in their favorite streams, turned their 

 attention, in the year 1841, to the close observation of the 

 habits of their favorite fish, the trout. Closely attending to 

 and watching the nature of the fish night and day during a 

 full moon in November of the year mentioned, after many 

 experiments they succeeded in devising a plan for the artifi- 

 cial fecundation of fish-spawn, which has made them famous 

 from one end of the civilized world to the other. Although 

 a work was written upon the subject and published by one 

 Jacobi, a. soldier in the Hanoverian army nearly a hundred- 

 years previous, the system was not put in practice for the 

 benefit of mankind until re-discovered by the French fisher- 

 men. The discoverers were presented with a medal by the 

 French Society of Emulation of the Vosges, but it was not 

 until 1848 that the Academy of Sciences, through the report 

 of M. Milne-Edwards, and on the proposition of M. Coste, a 

 model establishment was founded near Huningen, under the 

 auspices of the government ; now the most noted hatching- 

 establishment in the world. The poor fishermen were invited 

 to Paris and loaded with the highest honors. The report of 

 their success set the scientific world in motion, and all the 

 governments of the Old World and the New have slowly and 

 gradually put the system into practice. In England and 

 Scotland many salmon-rivers were restocked, and immense 

 excitement produced among the fraternity of anglers and 

 the lovers of fish throughout the United Kingdom. 



In the United States, the translation of the treatise of M. 

 Coste, on " Artificial Fish-Breeding," by W. H. Fry, Esq., 

 and its publication by Appleton & Co., in 1864, had an equal 

 effect on those interested in this country, and private hatch- 

 ing-houses were erected on rivers adapted to the purposes
