been at least 9,500,000 fish, 2 years old; moreover tlie seine skips a con- 

 siderable number. 



As there had been placed nearly 200,000 fish in Thisted Bi-edning this 

 year, i. e. about 16 per Tønde Land, 1 tried here to fish with the plaiee- 

 seine, and made in all 4 hauls, with a catch of 25, 15, 64, 94. Of these 7 

 only were from the preceding year (they were large), and 2 were marked 

 with holes. We must therefore suppose them to have been transplanted 

 this year — with exception of the seven — in all 191; but 16 Tdr. Land 

 have been fished over in these four liauls, and they ought therefore to have 

 given 16.16 fish = 256, if the seine had taken them all. We see that c. Va 

 of this number is missing, which third part then, I presume, has been skipped 

 by the seine. Had the meshes in the seine been so much smaller, that the 

 fish about one year had been caught also, the number of plaice in Nissum 

 Bredning would have been couuted, not at 97-, millions as now, but at 

 more than double that number. 



In Kaas Bredning we made two hauls with a plaice-seine. Result: 

 715 and c. 600 plaice. 



East of Venø we took in one haul 369 plaice, consequently nearly 100 

 per Td. Land. Here then, is no need of transplantation, at any rate not 

 this year. 



The next time the Sallingsund entered the Limfjord was in July 1900. 

 Tlie plaice at Thisted had gi'own well, and the fishermen got 10 Kroner per 

 fourscore. But foreign fishermen had, early in the year, fished up a great 

 number of the transplanted fish, as soou as tliese reached 10 indies to the 

 tip of the caudal fin, a length which some of them have already at the 

 time of transplantation. Before we get a law up there, forbidding the 

 landing of plaice under, at least, 10 inches to the base of the caudal fin, 

 this transplantation will never give any greater profit. 



In Kaas Bredning we now took 850 plaice in one haul, more, conse- 

 quently, than in the spring. 



In Nissum Bredning, at the piaces where we caught c. 2000 in each 

 haul in the spring, we now got only 360, 520, 420. Scarcely any was over 

 10 inches. On the sand at Thyborøn we found the fry of the year, 1 — 272 

 inches long. Here were, consequently, many fewer fish than in the spring, 

 and they were by no means larger. This was after a long period of easterly 

 gales, and it cannot, I think, serve as a standard with respeet to the num- 

 ber. (See p. 29, June 1899). 



July 30. and 31., 1900, we tried to fish east of Venø, but were much
