Abstract

This study was conducted to compare the condition factor of juvenile Nile tilapia (Oreochromis niloticus) caged in Lakes Sampaloc, Calibato, Mohicap, and Yambo in San Pablo, Laguna. The condition factor ranged from 1.50+ 0.10 to 1.96 +0.21. All values corresponded to good to excellent condition of fish. The CF from the UPLB Limnological Station and Yambo Lake was found to be significantly lower than those in Sampaloc, Calibato, and Mohicap. This may be attributed to the trophic conditions in Sampaloc, Calibato, and Mohicap. The nutrient levels in the eutrophic Calibato Lake and mesotrophic Sampaloc and Mohicap Lakes (Mendoza et al., 2019) were suitable for the growth of aquatic plants, which Nile tilapia feed on. Overfeeding from existing fish cages in the lakes is also thought to influence the high CF in these fish. Yambo had the lowest CF among all groups, although fish were still in good condition. Yambo is said to have lower nutrient levels which prolongs the growth of fish. The results of the study suggest that fish reared in Sampaloc, Calibato, Mohicap, and Yambo Lakes have high feeding activity and the conditions in the lake allow them to use their feeding source efficiently. Key words: condition factor, fish, lake, Nile tilapia
