EXPORTATION OF FISHES AND HATCHING APPARATUS. 1010 



changing ideas and making new experiments. I shall quote many 

 things from their reports, which I hope may be useful in Germany. 



Thus, Mr. Seth Green reports that recently he has paid special atten- 

 tion to the grayling, and that he has traveled thousands of miles in the 

 West in order to bring this valuable fish to the New York hatching es- 

 tablishment, and that hi-s eflbrts have been completely successful. But 

 the raising of shad is the subject on which Seth Green dwells with 

 special enthusiasm. He delights in relating how, in the year 1868, he 

 had asked Congress for a small financial aid for his experiments, but 

 how he was peremptorily refused, and repeatedly considered insane. 

 Now, when hundreds of millions of shad are hatched in the boxes in- 

 vented by him, the price of shad in the Hudson has already fallen to 

 20-25 pfennige apiece, which is about 8 pfennige per pound, and about 

 one-third of the price paid twenty years ago. 



Bat Seth Green is not yet satisfied with this, for in the Connecticut 

 Eiver, iu which 100,000,000 young shad had been placed, there were 

 recently caught in one net 3,560 shad, more than were ever caught at a 

 single haul during this century. The annual yield there has also beeu 

 greater than at any time since 1811, and the price for 100 fish has there- 

 fore been .$3, scarcely 4 pfennige per pound. Seth Green also suc- 

 ceeded four years ago in shipping his young shad from New York to 

 California, and large shad recently caught in that State, where formerly 

 not a single one had been seen, prove that the experiment was a com- 

 I)lete success. 



Besides his efforts in the line of shad-raising, Seth Green reports 

 splendid results in raising whitefish. This very excellent fish belongs 

 to the geuns Coregonus, and is about the same as our Lake Madue ma- 

 rcena. 



At the request of the State of Michigan, Seth Green sent (according 

 to his report to the above-mentioned piscicultural association) one of 

 his assistants to that State, with the so-called Holton apparatus, which 

 he considers the greatest piscicultural achievement of modern times. 

 Eight such apparatus, placed side by side in the hatching-house, only 

 occupy a space 16 feet long and 3^ feet broad, and can at one and the 

 same time hold at least 2,000,000 Coregonus eggs. At the suggestion of 

 Mr. Von dem Borne, I have asked Professor Baird for such an appa- 

 ratus, which, with his characteristic kindness, he has sent me immedi- 

 ately. According to the opinion of American pisciculturists, this is the 

 first apparatus hy which a very large number of the finer kind of fish 

 can be raised with very little expense. Might this apparatus also prove 

 successful with us I 



Equally with the Holton, the Clark apparatus is considered the best; 

 both of which you see before you, as well as a number of other imple- 

 ments used by American pisciculturists. We indulge in the reasonable 

 hope that they will also prove useful in this country. 



Well, gentlemen, with this apparatus there was actually raised for
