HAWAU (Cont. ) 



under experimental introduction as possible game fish include peacock-eye 

 cichiid, smallmouth bass and channel catfish. Efforts on the development of 

 fish shipping method include use of oxygen, sodium amytol, and activated car- 

 bon in the form of charcoal in plastic bags. This shipping method will be used 

 to introduce desirable exotics from other parts of the world as well as shipping 

 fish to various islands of the Territory for stocking.

9. Reef and Inshore Game Fish Management Research. (FA: F-5-R) 



This study is concerned with the ecology of reef fishes in Hawaiian waters. 

 Objectives are being accomplished by means of creel census and interviews with 

 shore casters and reef fishermen, underwater transects of selected areas with 

 self-contained diving gear and examination of stomachs and gonads of fish col- 

 lected by poisoning selected areas and spearing. Various species of fish ob- 

 served in underwater transects are being related to bottom types, current con- 

 ditions, locality aJid general areas to obtain some insight as to why the fish are 

 in certain areas and not in others and ultimately as to the productivity of certain 

 reef and inshore areas. 



Territory-wide; began January 1952, continuing; $10, 000; Vernon E. Brock,

1. Spawning and Early Life History of the Maomao (Abudefduf abdominalis). 



The maonnao is caught among the reefs by local sportsmen. Nothing is known 

 of its life history. An immediate objective is to discover its spawning habits and 

 to identify its eggs and larvae.

2. Response of Tuna to Stimuli. 



Objectives of the project are the continuation of a study to find a substance 

 chemically and/or visually attractive to tuna; and to conduct sea tests with at- 

 tractive substances and artificial lures to see if tuna can be attracted to the stern 

 of a fishing boat without the use of livebait.
