Abstract
A 6 and 8-week feeding trial was conducted to determine optimal feeding rate for parrot fish Oplegnathus fasciatus during the low temperature season. To estimate the optimal feeding rate calculated by weight growth rate, one year (mean body weight: 62.7 g) and the two year old parrot fish (mean body weight: 344.7 g) were stocked under low water temperature conditions. The optimal feeding rates in low water temperature condition of $15^{\circ}C$ were calculated as 1.61% of body weight (90% of satiation level) for the one year of 62 g, and calculated as 0.28% of body weight (80% of satiation level) for the two years old fish.
