[9] FAILURES AND SUCCESSES OF FISH-CULTURE. 445 



both iu the inland waters of East and West Prussia and in the region 

 of the Vistula. 



A striking illustration of the success of artificial salmon-culture is 

 furnished by the small coast river Ehede, flowing- into the bay of I*ut- 

 zig, north of Danzig. In the autumn of 1871, 2,100 uine-months'-old 

 salmon were, at the expense of the Government, furnished by the 

 hiitcbery of Prince Wied, at Aubacb, near Neuwied, and I was com- 

 missioned by the German Fishery Association to take them in charge. 

 There were placed in the river Ehede 1,000 of these fish, and the re- 

 mainder were sent to Stolpe in Pomerania. Mr. Muller, of Tschisch- 

 dorf, successfully conveyed these fish to their destination, and they 

 were placed in the Rhede, from which the salmon had entirely disap- 

 peared. In July, 1875, numerous salmon, measuring about 50 centi- 

 meters [20 inches] in length, ascended the river from the sea, evidently 

 some of the fish which we had placed in these waters four years ago 

 (German Fishery Association, 187G, p. 158). The hatchery founded in 

 Oliva by the chief forester, Mr. Liebeneiuer, has, since 1871, continued 

 to stock the Phede with young salmon (8,000 in 1874, and 31,000 in 

 1870). Gradually the Ehede salmon fisheries increased in imi)ortance ; 

 thus, dui'ing the Season of 1870-80 a much larger number of salmon 

 were caught than during the i)receding season (German Fishery Asso- 

 ciation, 1880, p. 103). As Mr. Liebeneiuer says in his report for 

 1880-81, the salmon fisheries in the waters near the mouth of tlie Vis- 

 tula and in the bay of Putzig have increased very considerably, but it 

 is difficult to obtain an exact estimate of the result of these fisheries, 

 as the fishermen endeavor to keep it secret. It is a fact, however, that 

 many hundred-weights of salmon have been shijipedfrom the stations 

 of Ehede, Kielaw, and Zappot. 



The Fishery Association of East and West Prussia has also given 

 some attention to the raising of Coregonus, although, so far, with one 

 exception to which we refer below, without much success, in spite of 

 the fact that, since 1870, very considerable quantities of young Coreg- 

 onus have been placed in diiierent waters. It is true that recently 

 some Coregomis have been caught in various lakes, but only occasion- 

 ally and in small numbers. (As I have done under the head of Eussia, 

 I would also advise in I^ast Prussia greater care of the Corajonm, es- 

 pecially during the spawning season.) The raising of Coregonvs lava- 

 retus has also met with numerous failures, although we are hapi)y in 

 I being able to chronicU^ at least one good result, in the bay of Putzig. 

 [After about 20,000 young fish of this kind had, in 1879, been phiced in 

 ja brook near Oliva, quite a number of these fish were, during the 

 .following years, observed in various parts of the bay of Putzig, and 

 lin the autumn of 1882 a larger number of these fish were caught than 

 ihad been the case for a long lime. (Report of the Fishery Associa- 

 Itiou of East and West Prussia for l882-'83, p. 27.)
