captured on each day's seining. In each instance 

 the snnall fish were retained alive for use as 

 bait, the mediunn-size fish were returned to the 

 pond, and the large fish were retained, usually 

 alive, for sale on the fresh-fish nnarket. It is 

 evident from table 1 that the main source of 

 tilapia was pond No. 6, which was seined on 

 five occasions and yielded a total of 436 pounds 

 of bait-size fish and 847 pounds of market fish 



in a period of about 4 months. In all, 634 pounds 

 (90 "buckets") of small tilapia were obtained for 

 the sea tests. 



Water reservoirs, such as those on the Ewa 

 Plantation, do not provide optimum conditions 

 for rearing tilapia. The water i s constantly 

 being replaced so that there is little opportunity 

 for natural foods, in the form of filamentous
