剑水蚤对拟穴青蟹初期蚤状幼体变态成活率的影响
Effects of Cyclops on the Transformation Survival Rate of Larvae of Scylla paramamosain
摘要:
通过对剑水蚤(Cyclops sp.)和拟穴青蟹(Scylla paramamosain)蚤状幼体游泳速度测定和不同密度的剑水蚤和拟穴青蟹幼体混合养殖试验。结果表明：剑水蚤的游泳速度1.31 ± 0.23 cm/min，蚤状幼体(Z1)的游泳速度0.48 ± 0.22 cm/min，剑水蚤的游泳速度是拟穴青蟹蚤状幼体(Z1)的2.7倍，两者的速度差异极其显著(p < 0.01)；剑水蚤密度20~100 ind/L时，蚤状幼体(Z1)的成活有显著差异(p < 0.05)而蚤状幼体(Z2)的成活率无显著差异(p > 0.05)。由于，剑水蚤的游泳速度迅速，繁殖速度快，与青蟹幼体造成水体空间的竞争，对青蟹池塘生态育苗造成不利。
Abstract:
The experiment of mixed culture and swimming speed of Cyclops sp. and larvae of Scylla parama-mosain were carried out. The results show that the swimming speed of Cyclops sp. is 1.31 ± 0.23 cm/min, and the larvae of Scylla paramamosain (Z1) is 0.48 ± 0.22 cm/min. The swimming speed of Cyclops sp. is 2.7 times of that of Scylla paramamosain (Z1), with extremely significant (p < 0.01). With the density of Cyclops sp. at 20 - 100 ind/L in the mixed culture, there was significant differ-ence in the survival rate in Z1, but no significant difference in Z2. Due to the faster swimming and reproduction, and the competition in water space with larvae of Scylla paramamosain, Cyclops sp. is unfavorable to larvae of Scylla paramamosain in the green crab ecological seedling breeding pond.
