ADMINISTKATION-REPORT 1902-03 _ XXXIV - 



Norway 



Sweden 



Norway employs the "Michael Sars", a steamer specially built for fishery 

 investigations. The director of the work is Dr. Johan Hjort, and his assistants are 

 Mr. Knut Dahl, Mag. E. Koefoed and Kand. A. M. Schweigaard. The laboratory for 

 these investigations is at Bergen and forms a portion of the building of the 

 ■'Fiskeristyrelse". 



Sweden takes part in the investigations of Committees A and ß especially 

 with regard to the fisheries in the Skager Rak. Investigations were begun there 

 in July 1903 with the hired .steamer "Betty". The director of the work is Dr. F. 

 Trybom and his assistant is Cand. Wollebaeck. 



Scotland Scotland has the steamer "Goldseeker" for these investigations. The director 



is Prof. D'Arcy W. Thompson, and his laboratory is at university College, Dundee. 

 His assistants are Dr. J. R. Fullarton, Dr. H. Chas. Williamson, and Mr. F. G. 

 Pearcey. Dr. T. Wemyss Fulton, Scientific Superintendent to the Fishery Board for 

 Scotland, whose laboratory is at the Bay of Nigg, Aberdeen, also takes part in 

 these investigations. 



Beigiunn (Belgium has not taken part in the investigations during the first year. The 



first seasonal cruise is to take place in August 1903 with the steamer "Ville 

 d'Anvers", and fishery investigations are to be carried on at the same time. The 

 director of the investigations is Prof. G. Gilson, Louvain.) 



Investigations 



with regard to 



the Migrations 



of Fishes 



The investigations which aim at the solution of the problem of the migra- 

 tions of fishes, especially of the cod and herring (Appendix B) have followed, so 

 far as the cod is concerned, the lines of definite investigations already begun on 

 the Norwegian coast. First of all, it has to be ascertained whether the cod which 

 seek the North Sea in winter, do not undertake the same movements, i. e. migra- 

 tions for the same purpose, as the cod which seek out the rising banks on the 

 Norwegian coast. The greater or less abundance of plankton (cod) eggs, the 

 distribution of which has to be studied especially in winter, may be taken as 

 guide for this purpose. The richest possible material of young forms of cod should 

 be collected, the fisheries statistics should be utilized, and the results attained by 

 the separate investigations should be completed by the experiences of the line- 

 fishermen of Holland, Scotland etc. The first year's work has already shewn that 

 investigations should also be set on foot to determine the distribution of the cod 

 in summer.
