| 中文摘要: |
| 【目的】为了提高黄鳍鲷、褐篮子鱼在 1 000 m2 斑节对虾南海 2 号养殖池塘内的生态效益。【方
法】试验比较了斑节对虾（Penaeus monodon）南海 2 号 - 黄鳍鲷（Sparuslatus）（混养黄鳍鲷处理）、斑节对虾
南海 2 号 - 褐篮子鱼（Siganus fuscessens）（混养褐篮子鱼处理）混养池塘内营养盐变化、颗粒物质含量、浮游
藻类、浮游动物以及养殖生物生长性能等指标在 105d 的变化。【结果】整个实验期间混养黄鳍鲷处理和混养褐
篮子鱼处理池塘水体中氨氮（NH4
+-N）、总氮（TN）、总磷（TP）、溶解性活性磷（SRP）、颗粒物质（TPM）
等均表现出增加的趋势；在实验中后期，混养黄鳍鲷处理池塘水体中的溶解态氮低于混养褐篮子鱼处理，然而
TN 含量却高于混养褐篮子鱼处理，至试验后期表现出显著差异；同时，混养黄鳍鲷处理池塘水体中的颗粒物质
含量高于混养褐篮子鱼处理，表明混养黄鳍鲷处理池塘水体中较高的 TN 含量是源于悬浮颗粒物质。两口混养池
塘内浮游生物和叶绿素 a 含量变化范围分别为 6.83~18.65 μg/L 和 5.34~16.24 μg/L，二者之间无显著性差异。【结
论】试验结果表明，黄鳍鲷的扰动作用可以促进池塘底部有机质向上层水体迁移，有利于降低 NH4
+-N、NO3
--N
等物质的积累和促进池塘养殖系统内物质循环；斑节对虾南海 2 号存塘率和鱼类取样结果表明，黄鳍鲷和褐篮
子鱼可以与对虾直接混养，取得更高的经济效益。黄鳍鲷和褐篮子鱼对养殖池塘不同粒径浮游植物的滤食能力
需要进一步研究。 |

| 【Objective】 The objective of the study was to explore the ecological benefits of Sparuslatus and Siganus
fuscessens in two 1 000 m2 aquaculture ponds for Penaeus monodon. 【Method】 A test was conducted to compare the
change of nutritive salt, content of particulate material, growth performance of phytoplankton, zooplankton and other indexes in P. monodon“Nanhai No.2”- Sparuslatus (Sparuslatus polyculture treatment, XZ pond) polyculture pond and the change
of such indexes in P. monodon“Nanhai No.2”- S. fuscessens (S. fuscessens polyculture treatment, XL pond) polyculture
pond in 105 days. 【Results】 The results showed that the contents of ammonia nitrogen (NH4
+-N), total nitrogen (TN), total
phosphorus (TP), soluble reactive phosphorus (SRP) and particulate matter in XZ pond and XL pond were increased during
the entire experiment. At the middle and later experiment period, the dissolved nitrogen in the XZ pond was lower than that
in the XL pond while the TN content in the XZ pond was higher than that in the XL pond and the difference became more
significant in the late experiment period. Meanwhile, the particulate matter content in XZ pond was higher than that in the XL
pond, which indicated that the higher TN content in XZ pond was from suspended particulate matters. The ranges of variation
of plankton and chlorophyll a content in the two ponds were 6.83-18.65 μg/L and 5.34-16.24 μg/L, respectively, showing no
significant difference. 【Conclusion】 The experimental results indicated that the bioturbation of Sparuslatus could boost the
transportation of organic matter from the bottom to the upper body of the pond, which was beneficial to reduce the accumulation
of NH4
+-N, NO3
--N and other substances, and promote the material circulation in the pond culture system. The survival rate
of P. monodon“Nanhai No.2”and fish sampling results indicated that the Sparuslatus and S. fuscessens could be cultured
with P. monodon“Nanhai No.2”directly to achieve higher economic benefits. Further study needs to be conducted on the
feed filtration capacity of Sparuslatus and S. fuscessens on different phytoplankton with different particle sizes in culture ponds
because of the importance of phytoplankton in the water. |
