INTRODUCTION. 



The practical problein.s connected with the fisheries have 

 been attacked (and in a large measure successfully solved) by a 

 rough-and-ready application of the method of trial and error, 

 and the scientific investigator has merely to follow after and ex- 

 plain why a given form of trap or method of lure is successful 

 with one species of fish and not with another. But there re- 

 main many unsolved problems of great economic importance 

 and it is the function of scientific research to contribute to the 

 solution of these problems in a more orderly and economical 

 manner, even though it often happens that the investigator best 

 qualified to solve the scientific problem has not the practical 

 knowledge of fishery matters necessary to apply his own results 

 to economic problems, and so his facts have to be worked over 

 from the other point of view before they become practically 

 useful.
