This study was conducted to analyze the sublethal effect of chlorpyrifos on the Feed Conversion Ratio (FCR), Sustainable Growth Rate (SGR), and carp behaviors. The concentration used 1/7 and 1/14 of the LC50 carp. The study was conducted with the number of fish per aquarium was five fishes, and the testing exposure time was 14 days. The results of the FCR and the SGR at a concentration of 1/7 and 1/14 LC50 was 0.2907 and 0.3031, and 1.551% and 1.9581%, respectively. Changes in behavior during exposure, a decline in appearance such as being alone in the corner of the aquarium, moving irregularly and stress (r = 0.75-1), lots of mucus (r = 0.800-1), anal excretion (r = 0.6-0.799), and breathe to the surface (r = 0.800-1). This situation happened because chlorpyrifos begins to affect the nervous system of carp to reduce other body functions. The FCR and SGR had a significant effect through the statistical test due to the chlorpyrifos concentration. Whereas in carp’s physiological behavior changes, there was no significant effect due to the level of concentration provided.
