3. Water Pollution Studies. 



Objectives of the project are to determine the physical, chemical and bio- 

 logical characteristics of the Chena River and their seasonal variations; the 

 quantity and strength of sewage and other wastes which it receives and the ef- 

 fect of these wastes on the stream.

1. Biology of the Aku or Skipjack (Katsuwonus pelannis). 



The aku or skipjack plays a small but important part in the Hawaiian troll 

 sport fishery and this study is undertaken to better understand the seasonal oc- 

 currence of aku in Hawaiian waters and the variations in abundance from one 

 season to the next. Detailed information on fishing effort and locality of catch 

 is obtained through interviews with captains of fishing vessels and information 

 on size composition of catch is obtained through length-frequency samples of 

 fish processed through the cannery and fresh fish markets. 



U. S. Fish and Wildlife Service cooperating; hdqrs. Honolulu; began 

 January 1954, continuing; $2,000; Vernon E. Brock, Leader; reports available. 



Address inquiries to: Vernor. E. Brock, P. O. Box 5425, Pawaa Sub- 

 Station, Honolulu, T. H. 



2. Fishery and Biology of Opelu or Mackeral Scad. 



The objectives of the project are to obtain information on the fishery and 

 biology of the nnackeral scad to form the basis of sound conservation measures. 

 The present laws regulating the fishery are based primarily on tradition and 

 not on sound biological information. 



Hawaii Marine Laboratory, University of Hawaii, cooperating; hdqrs. 

 Oahu; began February 1949, to close March 1954; $400; Yoshio Yamaguchi, 

 Leader. 



Address inquiries to: Vernon E. Brock, as in No. 1 above. 



3. Studies of Trolling Lure Efficiency. 



The object of this project is to determine the relative efficiencies of various 

 trolling lures commonly used in Hawaiian waters. Comparisons will be made 

 between lures in regard to effectiveness in catching various pelagic game fishes. 

 Considerations will be given to color, size, shape and action of the various lures 

 when conr\paring effectiveness. Trolling will be conducted only when vessel is 

 operating for other purposes and will be secondary to the vessel's other uses. 



Territory-wide; began January 1954, continuing; $200; Carl Nemoto and 

 Georges Gilbert, Leaders.
