中国鲎幼体阶段(黄皮鲎)饵料的初步研究

Feed Study of the Tachypleus tridentatus Juvenile

用杂鱼、星虫、牡蛎、乌贼、虾进行中国鲎幼体饵料种类、粒度以及白天和夜间摄食量差异等试验。结果表明：中国鲎幼体阶段 (黄皮鲎) 对乌贼的相对摄食量最大 (2.1 %)，而对小杂鱼的相对摄食量最少 (0.2 %)。中国鲎幼体阶段 (黄皮鲎) 均对粒度为 0.3～0.5 cm 的乌贼相对摄食量最大 (2.0 %)，对粒度为 2 cm 的乌贼相对摄食量最小 (0.1 %)。中国鲎幼体阶段 (黄皮鲎) 夜晚的摄食量明显大于白天；平均体重为 147.4 g 组的昼夜相对摄食量的差异最大 (白天为 0.8 %，夜间为 1.7 %)，平均体重为 258.7 g 组的差异最小 (白天为 1.1 %，夜间为 1.4 %)。

:Using fish, sipunculus,oyster sepia, and Lamellibranchia as feed the experiment is performed on the feed category, feed dimension and the difference between daytime and nighttime feeding amounts. It turns out that the juvenile Tachypleus tridentatus has the largest relative feeding amount on sepia ( 2.1 %), but the smallest relative feeding amount on fish (0.2 %). The juvenile Tachypleus tridentatus has the largest relative feeding amount on sepia (2.0 %), which dimension is 0.3～0.5 cm. And it has the smallest relative feeding amount on sepia (0.1 %), which dimension is 2.0 cm. The juvenil e tachypleus tridentatus has a far larger daytime feeding amount than the nighttime feeding amount. The largest difference is between the relative day time feeding amount (0.8 %) and the night time feeding amount (1.7 %) of the juvenile tachypleus tridentatus, which average weight is 147.4 g. The smallest difference is between the relative day time feeding amount (1.1 %) and the night time feeding amount (1.4 %) of the juvenil e tachypleus tridentatus, which average weight is 258.7 g.
