乌鳢仔龟的昼夜摄食节律和日摄食率的研究结果表明，乌鳢仔鱼摄食具明显昼夜节律性，其饱满指数２１时最高，１２时最低。每天在６～１５时之间停食３ｈ左右。日摄食率随饵料密度高低而变化，饵料密度为１０～１５个／ｍｌ、７～８个／ｍｌ和５～６个／ｍｌ时，日摄食率分别为１３．７１％、７．０４％和３．４９％。 Diurnal feeding rhythm and daily feeding rate of juvenile turtle hatchlings showed that the juvenile juvenile larva feeding conspicuously had circadian rhythms and its plumpness index was the highest at 21 and the lowest at 12. Every day between 6 and 15 o’clock stop about 3h. The daily feeding rate varied with the feed density, the daily feed intake was 13.71%, 7.04% and the feed intake was 10 ~ 15 / ml, 7 ~ 8 / ml and 5 ~ 6 / ml respectively 3.49%.
