Cero.<br/>A study was conducted to evaluate the growth performance of lettuce (Lactuca sativa var.<br/>Loose-leaf) and tilapia (Oreochromis niloticus var. Nile) in a small-scale aquaponics system. A<br/>pipe Nutrient Film technique constructed vertically was incorporated for the lettuce and an<br/>intensive culture method was used for the tilapia in the tank culture. The hydroponics system<br/>component was used for one cropping cycle. A stocking density of 63 fingerlings/m3 was used<br/>in aquaculture which resulted to 12 fingerlings per rearing tank. The hydroponics component<br/>used varied in three (3) different planting densities: Treatment 1 — 8; Treatment 2 — 12;<br/>Treatment 3 - 16 seedlings of lettuce. Ti lapia was reared for 25 days and thrived best in<br/>Treatment 2 which yielded an average weight of 49.97 g.<br/>However, the average harvested fish weight obtained in all of the systems was only<br/>75.21% of the average growth of fish that should be obtained in a 25-day span according to the<br/>Feed Conversion Ratio (FCR). Lettuce was also grown for 25 clays in which Treatment 1<br/>produced the highest average yield and thrived best in the system with an average yield of<br/>83.21 g.
