458 REPORT OF COMMISSIONER OF FISH AND FISHERIES. [22] 



prohibitory measures pointed out as an urgent necessity. The pro- 

 ])oso(l provisions of the new law go very far, prohibiting, among the 

 rest, the catcliing of salmon and salmon-trout in the sea from August 

 26 to April 14, and in the rivers from August 26 to April 30. (See 

 Deutsche Fischerei-ZeiUmg, 1883, p. 262.) 



DENMARK. 



Although Professor Malmgren does not mention this country in his 

 report, I must briefly refer to it. For tlie information given below I 

 am obliged to the editor of the Viborg Fishery Journal. 



As in Denmark the fisheries are not regulated by law, and prohib- 

 itory laws are unknown, artificial fish-culture is only carried on to a 

 very limited extent. Years ago salmon-cidture was carried on in Den- 

 mark, but only on a very small scale. In Jutland there are at present 

 only five fish-cultural establishments, principally engaged in raising 

 sea and brook trout. The quantity of eggs annually hatched in these 

 establishments varies from 20,000 to 300,000, and the fry obtained in 

 this way is planted in lakes, ponds, and brooks. The oldest lish-cult- 

 ural establislnnent in Jutland is the one in ^'iborg, which was founded 

 in 1865, in order to stock the lakes of that neighborhood with lake 

 tiout (Trutta tnitfa), which hitherto were not found there. The accli- 

 matization of this trout in the lakes near Viborg has been successful, 

 and this migratory fish has become a permanent ^sh. Since the Vi- 

 borg establishment has annually planted 20,000 of the fry of this fish, 

 several hundred pounds of Trutta trutta, mostly weighing from 5 to 10 

 l)ounds apiece, are annually caught in these lakes. The result would 

 be still better if circumstances did not prevent the use of large nets 

 and allowed only the use of small nets and lines. These acclimatized 

 sea trout differ from their relations in the sea by having a shorter and 

 broader shape ; their flesh is never red, but always white. Although 

 the Viborg establishment is only of limited extent, the results obtained 

 are nevertheless a proof of the of success artificial fish-culture. 



It is a very remarkable fact that of late years numerous schools of 

 young salmon have made their appearance near the Danish island of 

 Bornholm. Enormous quantities of these fish have been caught there 

 during the last few years. I would, in this connection, refer to an ar- 

 ticle by Finn on the fisheries of young salmon near Bornholm {Deutsche 

 Fischerei-Zeitung, 1883, p. 145), which, written in favor of prohibitory 

 measures, says that beyond a doubt these young salmon came from the 

 rivers of some other country on the Baltic, as no salmon-culture whatever 

 is carried on in Bornholm. It is probable that these young salmon are 

 the products of Swedish and German salmon -culture. Just as with us, 

 the Bornholm fishermen maintain that these young salmon are not 

 tSahno solar, but a smaller kind of salmon spawning in the sea, a vague 

 assertion whicli is only made in excuse of these reckless fisheries.
