The following progress reports covering the more important inves-

 in the main by the investigators in charge of the various projects. 



NORTH AND MIDDLE ATLANTIC FISHERY INVESTIGATIONS 



Investigations of fisheries of the Atlantic coast from Maine to 

 Virginia continued in 1932 to be concentrated on scientific research 

 needed to arrive at means of insuring the continued productivity of 

 the fisheries based on the more important food fishes: Haddock, 

 cod, flounder, mackerel, squeteague, scup, and butterfish. Decreased 

 funds necessitated curtailment of activities in all phases of the work 

 but more especially in the cod and flounder studies and the offshore 

 work of the haddock and mackerel studies involving use of the fish- 

 eries research ship Albatross II, the latter being out of service after 

 June 30 for lack of operating funds.
