would not be well to Hx it still higher can be proved only by future in- 

 vestigations and experiments. 



As to the turbot hi the Cattegat I can say that the milters often In- 

 come mature at a somewhat smaller length than in the German Sea; but 

 there does not seem to be any greater difference between the spawners in 

 these two seas. When therefore in England a size limit of 18 English 

 inches is proposed, a size limit of c. 15 Danish inches does not seem too 

 high with us, i. e. a turbot of c. 12 inches to the base of the caudal fin, or 

 weighing as a rule about 2 lbs., a size which is also considered suitable by 

 the fishmongers, as a turbot over 3 lbs. is generally paid for more than 

 tbree times as much per lb. as one under 3 lbs. 



For Bornholm a weight of c. l 1 / 2 lb. is minimum size with re- 

 spect to this fish, a size which I think may lie considered suitable there. 

 The question is there but of slight import. 



With respect to the brill it is supposed, accordiug to our present 

 knowledge of this fish, that c. 14 inches will be suitable with us. a length, 

 consequently, of o 12 inches to the base of the caudal fin — a Hsh of be- 

 tween 1 and 2 lbs. 



It is presumed that it will be far more advantageous in future to make 

 the size limits considerably higher both for turbot and brill. For these fish 

 can reach a much larger size than the proposed size limits, the turbot 25 

 inches with a weight of c. 25 lbs., and the brill c. 24 inches, though with 

 a considerably lower weight; but the proposed size limit will already be a 

 good step onward, compared to the present ones which for both specie 

 are only 8 inches to the base of the caudal fin. 



It is evident that fish which, when they reach their normal, mature size, 

 are so much larger (and broader) than the plaice as the two said species are. 

 must have suffered proportionally more by the eager fishing in the Catte- 

 gat than the plaice has done ; for the size of the meshes which has been 

 used has for this fish not been so unproportionally small as for turbot and 

 brill. We might really be tempted to believe that there are not, perhaps 

 enough of the mature fish to produce sufficient numbers of fecundated eggs 

 of these two species. I shall not here enter further into the question, how- 

 far artificial fecundation, carried on by every fisherman who catches mature 

 specimens of turbot and brill, and the placing of these eggs in the sea. 

 might be of any use. The matter would be, if the fishermen would 

 take an interest in doing so, without any cost to anybody, as the ripe eggs 

 and the milt were only to be pressed out of the fish into a dish, ami
