人工饲养的日本鳗鲡仔鱼死亡率高，很大程度上是由于其生长速度较低、畸形仔鱼比例较高。为了建立该物种的有效饲养方案，我们研究了水温和喂养方式对其生长和脊索后凸的影响。孵化后 165 天的幼虫在 24、25 和 27°C 的平均温度下饲养 28 天，每天喂食 4 或 6 次。在 24-25°C 饲养且每天喂食 6 次的幼虫中，幼虫生长率显着更高。然而，在 27°C 时，生长率显着降低，这表明由于较高温度下较高基础代谢率的成本增加以及目前使用的人工饲料的营养性能较低，导致代谢能量短缺。水温升高会促进脊索后凸，双向方差分析显示水温和进食频率对畸形有联合影响。这些发现表明同时控制环境和营养因素对于圈养健康鳗鱼幼体的重要性。
The high mortality rate of reared Japanese eelAnguilla japonicalarvae is largely due to lower growth rate and the higher rate of deformed larvae. To establish an effective rearing protocol for this species, we examined the effects of water temperature and feeding regimes on their growth and notochord kyphosis. Larvae at 165 days post hatching were reared for 28 days at mean temperatures of 24, 25 and 27 °C, and were fed 4 or 6 times per day. Larval growth rate was significantly higher in larvae reared at 24–25 °C and fed 6 times per day. However, growth rate was significantly reduced at 27 °C, suggesting a shortage of metabolic energy due to an elevated cost of the higher basal metabolic rate at higher temperatures and low nutritional performance of currently used artificial diet. Notochord kyphosis was promoted by elevated water temperature, and two-way ANOVA showed that water temperature and feeding frequency had combined effects on the deformity. These findings suggest the importance of concurrently manipulating both environmental and nutritional factors to produce healthy eel larvae in captivity.
