在室内流水条件下测定不同温度（１５℃、２０℃、２５℃和３０℃）对长吻幼鱼摄食，生长及饲料转化效率的影响。结果表明：长吻摄食与生长的起始温度为１５℃；适宜温度区为２０—３０℃；最适温度为２５℃左右。水温为１０℃时，长吻 基本不摄食，水温为１５—２５℃时，长吻摄食率、生长率随永温升高而显著增加，２５℃和３０℃组间差异不大。饲料转化效率随水温上升明显提高，但水温升至３０℃时，饲料转化效率有下降的趋势。长吻幼鱼日投饵量可根据经验公式：Ｃ＝０．１４８Ｔ￣（１．６２６）Ｗ￣（－０．５２１）计算。
The effects of different temperature (15 ℃, 20 ℃, 25 ℃ and 30 ℃) on food intake, growth and feed conversion efficiency of juvenile larva were tested under indoor flow conditions. The results showed that the initial temperature of feeding and growth was 15 ℃, the suitable temperature range was 20-30 ℃ and the optimum temperature was about 25 ℃. When the water temperature was 10 ℃, the long kisses basically did not ingest. When the water temperature was 15-25 ℃, the feeding rate and growth rate of long kisses increased significantly with the increase of the temperature, but no significant difference between 25 ℃ and 30 ℃. Feed conversion efficiency increased significantly with the rise of water temperature, but when the water temperature rose to 30 ℃, feed conversion efficiency tended to decrease. The feeding amount of juvenile fishes can be calculated according to empirical formula: C = 0.148T ~ (1.626) W ~ (-0.521).
