Remarks on Dr. Petersen's Report of the Danish 

 Biological Station for 1895. 



By 

 Ernest W. L. Holt. 



It may be predicted of a Eeport by Dr. Petersen that it is sure to 

 contain matter of great interest, both to the ichthyologist and to 

 the student of fishery questions ; and the volume for 1895 is assuredly 

 no exception to the rule. 



The subject dealt with is the plaice fishery of the Lim fjord, an 

 arm of the sea which pierces the Danish peninsula from Tliyboron, 

 on the west coast, to Hals, on the Cattegat. Such a geographical 

 feature is quite without parallel in our comparatively mountainous 

 countries, and may even be said to present difficulties of comprehension 

 to those who have not had an opportunity of visiting Denmark. Indeed, 

 the physical conditions are so different from our own, that it must 

 be at once acknowledged that the mass of information so carefully 

 collated by Petersen cannot be made of direct use in connection with 

 any of our own fisheries. Indirectly, however, the Danish work 

 will be found to be of the highest importance, and well worth the 

 attention of those concerned with British fisheries. 



A glance at Petersen's map shows that the Lim fjord consists of 

 "brednungs," or broads, connected with each other by somewhat 

 narrow channels of various lengths. The westernmost (Nissuni) 

 broad communicates with the sea (since the beginning of the present 

 century) by means of an inconsiderable opening in the barrier ridge 

 of Hasboore, while the Liv broad, the easternmost, and by far the 

 largest of the series, is separated from the Cattegat by a long and, 

 for the most part, narrow sound. Previous to the breakdown of the 

 Hasboore barrier we learn that plaice were only found in the sound 

 last mentioned, viz., that between Hals and Logstor, and only then, 

 as now, in quite inconsiderable numbers, even in that part. Con- 

 sequently the fish, which now form the object of a most important
