本文主要在实际观察值的基础上，利用发育反应方程Ｃ＝ＫＷＹ与功能反应Ｈｏｌｌｉｎｇ、Ｉｖｌｅｖ方程对２～１０日龄的牙鲆仔鱼的摄食能力进行了计算与预测。其结果表明：牙鲆仔鱼在２～６日龄、轮虫饵料密度不超过３０００ｉｎｄ· Ｌ－１的水体中，摄食强度不超过 １７ μｇ· ｈ－１；随着日龄的增加，摄食强度迅速增强，在 ４、６、 １０日龄、饵料密度为３０００ｉｎｄ·Ｌ－１的水体中，摄食强度分别是１．３５、１．６８、３．８９μｇ·ｈ－１。牙鲆仔鱼的摄食发生率随仔鱼的发育而加大，仔鱼在 ２日龄、饵料密度为 １５ ０００ ｉｎｄ·Ｌ－１的水体中，其摄食发生率仅为 ０．６９μｇ·ｈ－１，而在 １０．４日龄时，同饵料密度下的摄食发生率为１８．７２ μｇ·ｈ－１，后者是前者的２７倍。食饵操纵时间、饵料搜寻时间随仔鱼的发育而迅速下降：仔鱼在２、１０．４日龄的食饵操纵时间分别为０．４８５、０．０４０ ｈ．μｇ－１，前者是后者的 １２倍多，而在饵料密度为 １５ ０００ ｉｎｄ·Ｌ－１下，搜寻时间分别为 １４４９、００５３ ｈ．μｇ－１，前者又是后者的 ２７倍多，亦即是说，仔鱼在初孵前几天的摄食能力较低，到后期逐步提高。 Based on the observed values, the feeding ability of larvae of Paralichthys olivaceus aged 2 ~ 10 days was calculated and predicted by using the development reaction equation C = KWY and functional reaction Holling and Ivlev equations. The results showed that the dietary intensity did not exceed 17 μg · h-1 in larvae of larvae at 2 to 6 days of age and rotifer feeding density of 3000 ind · L-1. With the increase of age, the feeding intensity rapidly At 4, 6 and 10 days of age, the feeding intensities were 1.35, 1.68 and 3.89 μg · h-1 respectively in water with 3000ind · L-1 dietary densities. The incidence of feeding of Japanese flounder larvae increased with the development of larvae. The feeding rate of larvae was only 0.69μg · h-1 in 2-day-old water with 15 000 ind · L-1 of feeding density At the age of 10.4 days, the incidence of feeding at the same feed concentration was 18.72 μg · h-1, which was 27 times higher than the former. The prey time and feed seek time decreased rapidly with the development of larvae. The larvae maneuvering time of larvae at 2, 10 and 4 days were 0.485 and 0.040 h, respectively. μg-1, the former is more than 12 times of the latter, while the searching time is 1449,0053 h at the feeding density of 15 000 ind · L-1. μg-1, the former is 27 times more than the latter, that is to say, larvae feeding ability is low a few days before the first hatch, gradually increased to the latter.
