INTERNATIONAL FISHERY INVESTIGATIONS 603 



hydrographical researches can be carried on otherwise than 

 by a number of vessels working simultaneously over the whole 

 of the north European area. Fishery statistics are at the 

 present time in a most unsatisfactory state, both in Great 

 Britain and in the other North Sea fishing countries. Much 

 information that is quite essential in the inquiry into funda- 

 mental fishery questions is not afforded by the fishery statistics 

 of this or of any other country ; the statistics that do exist 

 are collected and tabulated differently in the various fishing 

 countries. It is certainly most desirable that in the recon- 

 struction of the organisation for the joint prosecution of fishery 

 investigations, which will be entered upon in the course of next 

 summer, the necessity for the retention of some machinery 

 on an international scale, both for the collection and collation 

 of fishery statistics, and for the continuance of the present 

 hydrographical investigations, should be considered.
