摘要

近来，⻢来西亚南⽅鲎的数量持续减少，其原因主要为栖息地⽔质不佳之问题。⽔质是影
响鲎存活率的主要环境因素，而了解与改善⽔质正是提⾼鲎存活率的关键。为了提⾼鲎存
活率，并降低其死亡率，本组⾃制了过滤系统，设之为实验组，并另设⼀原有蛋⽩质分离

器之系统，设之为控制组。2024 年 2 ⽉底⾄ 3 ⽉初，本组⼀共⽤了 15 天将装有⾃制过滤
系统之⽔缸与装有蛋⽩质分离器之⽔缸进⾏⽔质与幼年南⽅鲎存活率之⽐较并将上述数据
记录。本实验之实验组在实验结束时将死亡率维持在较低⽔平，同时在⽔质数据⽅⾯也较
控制组稳定,故实验宗旨达成，⾃制过滤系统被证实有效。

Abstract

In recent years, the number of Malaysian Tachypleus gigas have been declining.
The main reason for this phenomenon is the poor water quality of its
habitats.Water quality is the main environmental factor that affects T.gigas’
survival rate. Understanding and improving the water quality is important to

increase the survival rate of T.gigas. In order to increase the survival rate and
reduce the mortality rate of T.gigas, we designed a self-made filtration system and
grouped it Experiment. To make a comparison, we set up another system with a

protein skimmer and grouped it Control. At the end of February to early March
, we spent days observing and comparing the water quality and survival
rate of juvenile T.gigas of both systems, then recorded the data. The mortality
rate of Experiment remains low and the water quality was better in Experiment
compared to Control. This means that the objective of the experiment was

achieved and the hypothesis was accepted, the self-made filtration system was
proven effective.
