32 An Angler's Paradise. 



he placed a layer of gravel, and laid upon it a quantity of salmon 

 eggs. His supply of water came from a cistern, and flowed 

 through an ordinary tap, the only precaution being to keep the 

 stream constantly going, and this, it may as well be stated, is 

 an absolute necessity, if trout or salmon ova are to be success- 

 fully hatched. 



In the year 1854 Professor Coste founded the important 

 fish-cultural establishment so well known as Hiiningen, and by 

 its means large quantities of fish ova were distributed. Being 

 situated in Alsace it fell into the hands of the German Govern- 

 ment in 1871, and under the directorship of Mr. Herman Haack 

 has since then, as before, done very good work. The hatchery 

 and ponds are said to cover upwards of eighty acres, which 

 gives some idea of 'the extent of the work. A large space in 

 the chief building is devoted to the hatching of the ova of the 

 Salmonidcz, but ova of many other kinds are dealt with. From 

 half-a-million to a million salmon ova are hatched each season 

 for stocking the waters of the Rhine, which is near, and the 

 Government pays for this work. 



The young salmon are reared in concrete tanks, which are 

 also used for other fish, and answer the purpose admirably. 

 The Governments of Germany, Switzerland, and the Nether- 

 lands, have shewn their interest in the important work of fish- 

 culture, which has been going on for some years, and it is largely 

 due to this fact that it has made such rapid strides in these 

 countries. Public waters are* being restocked and private enter- 

 prise is encouraged. In Saxony fish-culture has been helped 

 by courses of lectures which have been delivered by Professor 

 Nitsche of the Academy of Forestry. The lectures, illustrated by 

 diagrams, specimens and apparatus, have dealt with the subject 

 in a very exhaustive manner. 



The knowledge which had been gained was by degrees 

 increased and fish-culture has prospered in France, until to-day 

 there exists at Gremaz in the Department of the Ain, one of 

 the most perfect systems of fish-culture of the present time. 

 Fish are reared on the natural food produced in the water, and 

 herein lies one of the great secretsjpf success in the rearing of 

 trout fry.
