REARING TILAPIA FOR TUNA BAIT 



THE PAIA HATCHERY 



DESCRIPTION OF FACILITIES 



Tanks 



The hatchery was situated near the sugar mill 

 at Paia, Maui. The portion of the stable that was 

 renovated consisted initially of a long, concrete- 

 walled walkway with a narrow trough along each 

 wall. On the outer side of each trough was a series 

 of 45 individual stalls (fig. 1). To convert these 

 structures into a tilapia-producing plant, the 

 central walkway was walled at each end and par- 

 titioned in the middle to create two large brood 

 tanks, A and B. The two narrow troughs and 

 the 90 stalls were converted into fry tanks (fig. 

 2). Inflow pipes and drains were installed in all 



tanks. The dimensions of the various tanks are 

 given in table 1. 



A small building was moved onto the grounds 

 and modified for storage of feed and equipment.
