EXPORTATION OF FISHES AND HATCHING APPARATUS. 102 o 



lution was formed at ouce ; our aim must be to increase the number of 

 may-fish, just as the number of shad has been increased in America; 

 to increase its number in the Rhine, and to place large numbers of young 

 may-fish in the Weser and the Elbe, from both of which rivers they can 

 go to the North Sea to seek their food. In both of these rivers it occurs 

 occasionally, although there is no protection for it whatever. 



The question remains to be answered whether the Baltic can supply 

 sufficient food for this fish, and whether, therefore, the rivers flowing 

 into the Baltic could be stocked with may-fish. 



The attempts made during the last two summers to cultivate this fish 

 were unfortunately not successful. All our efforts will remain very un- 

 certain, unless we can induce the Dutch to make a short pause in their 

 barring of the Ehine, at least for some hours every week during the 

 season when these fish migrate. But this coming summer I certainly 

 look for some successful results, since our energetic colleague, Mr. 

 Eckardt, who has been so eminently successful in his piscicultural efforts, 

 has promised to devote some weeks entirely to these experiments. He 

 has succeeded in placing before us this day in this glass vessel which 

 you see here hundreds of live Blaufelclien from the Lake of Constance 

 and Marcenas from the Madue Lake. If we are successful, and why 

 should we not hope for it ? the may-fish will become with us, as the shad 

 in America, a great benefactor of the masses of our population. 



The highly praised American whitefish [Goregonus albus) also finds his 

 near relation in the beautiful species of Coregonus which we have, the 

 Marcena of the Madue Lake, the Schaal Lake, and the Puis Lake, as 

 well as the Blavfelche of the Lake of Constance. We are able to 

 chronicle fine results obtained in this direction during the last few 

 months. Mr. Eckardt has succeeded in obtaining a large quantity of 

 well-impregnated spawn of the Madue marcena, and he has distributed 

 a good deal of it, so that some days ago we could place several thou- 

 sands of the young fish in the Tegern Lake and the Lake of Constance. 

 Mr. Haack, of Hiiningen, could also report very encouraging results of 

 the cultivation of the Blaufelclien in the Lake of Constance; and we 

 succeeded in placing about 40,000 of these in this lake, and several 

 thousands in the Tegern Lake. Thus you see, gentlemen, that we have 

 not been altogether unsuccessful in the field of practical pisciculture, 

 and if we have not been able to show as great results as America, it 

 must be remembered that the educated classes have so far not taken 

 any great interest in our efforts, and that the means at our command 

 have been very small. Let us hope that there may soon be an im- 

 provement in both respects. 



I may well say with a feeling of pride that in gentlemen like von 

 dem Borne, Eckardt, Schuster-Freiburg, Haack-HUningeu, Brussow of 

 Schwerin, Mohnike and Strauss of Stolp— just to mention a few of the 

 more than one hundred and fifty German presidents of piscicultural in- 

 stitutions — we have the guarantee that Germany can emulate America 

 in this respect. But this requires a good orgauizitiou.
