 been gathering data which will be valuable as a basis for future legis-

 fresh water, which is of much importance, is accumulating. Further 

 experiments of this kind have been instituted. 



Several important developments in California fisheries have necessi- 

 tated careful study in order that control measures might be instituted. 

 Of particular import is the growth of the long-finned tuna or albacore 

 indu.stry. The output of canned tuna now is more than double the 

 value of the output of salmon or sardines. The tuna packers them- 

 selves are anxious to know more about the migration and life history of
