Abstract
This study aims to determine the optimal aeration level for several variables of water quality, physiological conditions and the increase in the weight of juvenile tinfoil barb (Barbonymus schwanenfeldii). The design used in this study was a completely randomized design (CRD), as the treatment is the aeration level, which is 2, 6, 10 and 14 L min to each aquarium (40 L of water). The observed variables consisted of water quality (temperature, dissolved oxygen (DO), carbon dioxide (CO2), ammonia (NH3-N)), physiological variables (lactic acid levels, levels of oxygen consumption, nitrogen retention and energy retention), and absolute weight gain and feed conversion ratio (FCR). The results showed that DO was higher with increasing aeration levels, from an average of 6.49 to 7.99 mg L -1 -1 , CO2 and ammonia (NH3-N) could still be tolerated by fish to grow. Oxygen consumption and lactic acid levels in the muscles increase with increasing aeration levels. The highest nitrogen retention and energy retention were achieved at 10 L min aeration treatments, which were 40.77% and 34.53%, respectively. The use of 10 L min -1 aeration can also produce the highest absolute weight gain (WG), which is an average of 404.20 g and the lowest FCR with a value of 1.26. -1
