1. The Biology of the Aholehole (Kuhlia sandvicensis). 



The immediate object is to determine the feasibility of rearing aholehole in ponds as 

 a baitfish for the livebait txina fishery. Determinations include the rate of growth 

 in length and weight for fish in the natural habitat and in ponds and tanks; the food 

 and feeding habits; spawning areas, habits and season; description of the eggs and 

 larvae; the range of temperature, salinity and oxygen concentration in the natural 

 environment and the range of tolerance to these factors. 



Oahu; in cooperation with the Industrial Research Advisory Council; began January 

 1952, to be conr\pleted in April 1953; $7, 000; results to be published by Industrial 

 Research Advisory Council.

2. Reaction of Tuna to Chemical Stimuli. 



The objectives of the project are: To investigate further certain extracts of tuna and 

 other fish flesh and viscera, which had previously been found to attract tuna held 

 in captivity; to identify the attractive compound(s) in the extracts; to screen various 

 chemical substances in an attempt to discover an attractant; to discover methods 

 of preparation and preservation of the tuna extract which would serve to provide 

 large quantities for sea tests on "wild" tuna. 



Hawaii Marine Laboratory, Coconut Island, Oahu, T. H. ; Fish and Wildlife Service, 

 Pacific Oceanic Fishery Investigations, cooperating; began June 1952, to be 

 completed in May 1953; $8, 000.

1. Investigation of Tunas about the Hawaiian Islands (Proj. 82). 



A project to investigate the tuna resources in the vicinity of the Hawaiian Islands with 

 the view of determining their magnitude; how to extend the season and area of fish- 

 ing; and the extent of the bait resources in the leeward islands of the Hawaiian 

 group.
