PROPAGATION OF STURGEON IN GERMANY.

character made iu every part of Germany would result iu furnishing a tolerably cor- 
rect idea of the mode of life of those species. It is necessary, however, that the sta- 
tions for making observations should be carefully selected, as very erroneous results 
might be obtained through iusufflcient and inexact data. The stations should be 
visited from time to time by competent persons, who should personally give instruc- 
tions how to conduct the observations. We are now publishing a large edition of our 
salmon and sturgeon record-books, and shall take the liberty to forward copies for 
your inspection. 
Hoping that it will soon be possible to answer all of the above questions in a 
satisfactory and exhaustive manner, I am, very respectfully. 
Your obedient servant, 
Dr. Pancritius. 
[From Circular No. 6, 1886, of the German Fishery Association, Berlin, December 30, 1886.] 
At the request of the German Fishery Association, the board of directors of the 
Central Fishery Association of Schleswig-Holstein has continued, in 1886, its efibrts 
in regard to sturgeon-culture, and has attained better results than in any previous 
years. The work of this year was important not only on account of the many thousands 
of sturgeons that were hatched, but also by reason of the greater experience gained 
by the sturgeon fishermen. If sturgeon-culture is to be established upon a secure 
basis in the future, this can only be brought about through the willing and intelligent 
aid of the fishermen. 
All that has been accomplished in the matter of sturgeon-culture, has been done 
in the special interest of the sturgeon fishermen, a fact which they now recognize ; 
and in a few years we hope to be able to report that those fishermen on the Elbe and 
Eider have hatcheries of their own, in which, with the aid of the German Fishery Asso- 
ciation, millions of sturgeons will be produced every year. 
From the daily reports of this year’s work we quote the following : 
Mr. Eisner, a fish-culturist, directed the work during June, 1886, at the Elbe sta- 
tions of Gliickstadt, Kollmar, and Twielenfieth and on the Eider near Thielenhemme. 
Hatching apparatus was supplied, and rewards of 50 marks [$11.90], 75 marks 
[$17.55], and 100 marks [$23.80] were offered for lots of 10,000, 20,000, and more young 
sturgeon hatched at these stations. 
July 7 our faithful co-worker, Mr. J. Mohr, of Gliickstadt, telegraphed that 
sturgeon had been hatched near that place. Mr. Eisner immediately went to Gliick- 
stadt and found live embryos in three of the hatching-boxes. July 8 the fish were 
ready for planting to the number of about 200,000. This number was calculated upon 
the basis of 68,888 eggs to the i)ound of mature roe. 
Mr. Mohr reports as follows : On Saturday, July 3, about 11 o’clock a. m., Mr. 
Kuhnerti, a fisherman, arrived from Storort with a mature spawning sturgeon. I was 
immediately informed of the fact, and, in conjunction with Mr. Stepnetsch and several 
fishermen, commenced to impregnate the eggs. We had two mature males secured by 
a chain, and the milt of both of these was used in that connection. About 2 o’clock 
iu the afternoon the work of impregnating the eggs was finished, and all the eggs were 
placed in three hatching-boxes. On Wednesday morning, about 8 o’clock, or ninety- 
three hours after impregnation, the first free embryos were observed in the apparatus, 
and about noon, so far as could be determined, all the eggs had been hatched. For this
