Abstract

The green-lipped mussel Perna viridis’ sensitive nature and characteristic as a benthos organism that filters the sediment in its environment make it one of the possible bioindicators for pollution in the aquatic ecosystem. The present study aimed to determine the percentages of total shell deformities in comparison to the past data in the coastal waters of Peninsular Malaysia. It was found that several types of discontinuous, continuous, and unexplained shell abnormalities contributed to the overall range of shell deformities of 15.8–87.5%, which was greater in comparison to that (0.0–36.8%). The present study showed that the highest overall proportion of shell abnormalities occurred in Teluk Jawa, whereas the lowest percentages were found in Kampung (Kg.) Pasir Puteh. The regulative mechanisms at the well-known polluted sites at Kg. Pasir Puteh could be the explanation. Further research should be conducted to determine the degree of heavy metal that may be the source of these malformations in the mussel shells.

绿唇贻贝的壳畸形:马来西亚半岛西海岸的发生和潜在的环境压力

绿唇贻贝(Perna viridis)的敏感性和作为底栖生物过滤环境中沉积物的特性使其成为水生生态系统污染的可能生物指标之一。目前的研究旨在确定总壳畸形的百分比，比较过去的数据在马来西亚半岛的沿海水域。研究发现，不连续、连续和不明原因的几种类型的壳异常对壳畸形的总体范围的贡献为15.8-87.5%，大于0 - 36.8%。目前的研究表明，在泰鲁克爪哇发生的外壳异常的总体比例最高，而在甘榜(Kg)发现的百分比最低。东巴西Puteh。香港著名污染地点的调控机制。帕西尔·普特可能是解释。应该进行进一步的研究，以确定重金属的程度，这可能是贻贝壳中这些畸形的来源。
