On the Plaice in the Limfjord 1899 and 1900. 



Owing to the importance attached to the transplantation of young plaice 

 into the Limfjord, it is of interest to kaow the uumerousuess of tliis fry 

 there, in the various years. Every time the Sallingsund has been in the 

 Limfjord, some hauls with plaice-seines have been made in Nissum Bred- 

 ning, in order to investigate this matter. Thus, on the 30. of June 1899, 

 a haul was made near the Tyhorøn Cunal in the fjord. About 2800 plaice, 

 between 7 and 10 inches in length, were caught in a plaice-seine, whose 

 arms were c. 25 fathoms long. A haul with a seine with small meshes 

 (1 square iuch) showed that, besides the fry of the year, there were plaice 

 of two other years, those P/i year old and those of 2 years and a quarter. 



July 1., 1899, we took with a plaice-seine in Kaas Bredning, in one 

 haul, c. 1200 plaice, 400 of which were over 10 inches in length; the lar- 

 gest was 13 inches. 



In Vilsund we caught in one haul ouly 5 plaice, but 13 codfish. 



In Thisted Bredning a haul was made which gave 36 plaice, only 8 of 

 which were under 10 inches. The largest was 137^ inches. Tliere were none 

 of the proper marks (2 holes) on these; but the fin-rays of several were 

 damaged, so that we could see they had sailed in a fishiug-boat with a well, 

 and were transplauted fish. 



April 25., 1900, and the following days, we made some hauls in Nissum 

 Bredning, partly to count how many plaice there could be takeu in the various 

 piaces in this expansion of the fjord, partly to trausplant some more plaice 

 tlian usual into Thisted Bredning, for the purpose of investigatiug whether
