仔鱼大小对水母捕食强度的影响数据集
收藏资源简介:
本实验研究水母对不同大小仔鱼的捕食强度变化情况。海蜇实验中分别选用了伞径11.7 mm和21.1 mm两种规格的海蜇幼体,褐牙鲆仔鱼年龄分别为0, 3, 5 dph;海月水母实验中分别选用了伞径35 mm, 75 mm和99 mm三种规格的海月水母,褐牙鲆仔鱼的年龄为3-21 dph。研究结果表明,幼海蜇和海水水母对褐牙鲆仔鱼的捕食率均随仔鱼的日龄的增长而下降。相关结果为为科学认识水母对仔鱼的捕食过程提供了科学依据。
This experiment investigates the variation in predation intensity of jellyfish on fish larvae of different sizes. For the Rhopilema esculentum (edible jellyfish) trial, two sizes of juvenile jellyfish with umbrella diameters of 11.7 mm and 21.1 mm were selected, and the larvae of Japanese flounder (Paralichthys olivaceus) were at 0, 3, and 5 days post-hatching (dph) respectively. For the Aurelia aurita (moon jellyfish) trial, three sizes of moon jellyfish with umbrella diameters of 35 mm, 75 mm, and 99 mm were selected, and the Japanese flounder larvae were aged 3–21 dph. The results demonstrated that the predation rates of both juvenile R. esculentum and moon jellyfish on Japanese flounder larvae decreased with increasing larval daily age. These findings provide a scientific basis for understanding the predation process of jellyfish on fish larvae.
