Two trials were conducted with different durations and intensities of food deprivation to investigate the compensatory growth, food utilization and body composition of the ricefield eel, Monopterus albus. The different feeding protocols were tested for 64 days in two stages: experiment 1 comprised four levels of feed deprivation (1‐day starvation and one‐day refeeding (S1F1), 2‐day starvation and 2‐day‐ refeeding (S2F2), 4‐day starvation and 4‐day refeeding (S4F4), 8‐day starvation and 8‐day refeeding (S8F8)) and a control level (daily feeding). Experiment 2 comprised three levels of deprivation (1‐day starvation and 2‐day refeeding [S1F2], 1‐day starvation and 3‐day refeeding [S1F3], and 1‐day starvation and 4‐day refeeding [S1F4]). In experiment 1, the final body weight and specific growth rate (SGR) of the fish in all feed deprivation groups were significantly lower than those of the control; however, the feeding rate (FR) in all feed deprivation groups was significantly higher than that of the control. The feed efficiency (FE) in the feed deprivation groups was significantly lower than those of the control. In experiment 2, the final body weight and SGR in S1F3 and S1F4 approached the mean weight of the control. FR increased in S1F3 and S1F4, but FE did not differ among groups and was higher than in experiment 1, indicating that feed utilization efficiency increased with prolonged refeeding time. Overall, under the experimental conditions, feed restriction for 1 day followed by longer refeeding might represent an adequate management strategy in M. albus rearing.

适当的剥夺饲料的持续时间和强度可促进稻field（Monopterus albus）的代偿性生长反应

进行了两个试验，分别对食物剥夺的持续时间和强度进行了研究，以调查稻田Mon（Monopterus albus）的补偿生长，食物利用和身体成分。在两个阶段中测试了64天的不同喂养方案：实验1包括四个水平的饲料剥夺（1天饥饿和1天再喂养（S1F1），2天饥饿和2天再喂养（S2F2），4每天饥饿和4天补料（S4F4），8天饥饿和8天补料（S8F8））和控制水平（每天喂食）。实验2包括三个剥夺水平（1天饥饿和2天补料[S1F2]，1天饥饿和3天补料[S1F3]，1天饥饿和4天补料[S1F4]）。在实验1，所有饲料剥夺组的鱼的最终体重和比生长率（SGR）均显着低于对照组。但是，所有饲料剥夺组的饲喂率（FR）明显高于对照组。饲料剥夺组的饲料效率（FE）显着低于对照组。在实验2中，S1F3和S1F4的最终体重和SGR接近对照组的平均体重。S1F3和S1F4中的FR增加，但各组之间的FE并无差异，并且高于实验1，表明饲料利用率随着时间的增加而增加。总体而言，在实验条件下，限制饲喂1天，然后再进行更长的饲喂，可能表示白M的饲养有足够的管理策略。
