Fish Diversity in the Peusangan River, Central Aceh Regency, Aceh Province: A Study on the Relationship between Fish Diversity and Environmental Factors
Introduction
The Peusangan River, located in Central Aceh Regency, Aceh Province, is a vital water body that supports a diverse range of fish species. However, the impact of human activities and environmental changes on the river's ecosystem is a pressing concern. This study aims to analyze the fish diversity index and its relationship with the physical and chemical factors of water around the river. The research was conducted from September to October 2018, using the purposive sampling method, which involved the determination of four sampling stations.
Understanding Fish Diversity in the Peusangan River
Fish diversity is a crucial indicator of the health of river ecosystems. The diversity of fish species reflects the genetic diversity and ecosystem stability of the habitat. In this study, ten species of fish were classified into four orders and six families. The highest density of fish was recorded at station 2, with a value of 1.89, while station 4 had the lowest diversity index value of 1.52. This study also found a strong relationship between current velocity and phosphate levels with fish diversity in the Peusangan River.
Analysis of Fish Diversity and Environmental Factors
The diversity of fish in the Peusangan River provides an important picture of the health of river ecosystems. The high diversity index shows that the habitat is able to support various fish species, which reflect the diversity of genetic and ecosystem stability. Conversely, the low diversity index in station 4 may indicate an environmental problem that needs to be overcome, such as pollution or decrease in habitat quality.
The physical and chemical factors of water greatly affect the presence of fish. Parameters such as temperature, pH, and dissolved oxygen levels play an important role in determining the comfort and survival of certain fish species. For example, extreme temperatures or low oxygen levels can inhibit the growth of fish population. Likewise with phosphate, which if excessive can cause eutrophication, resulting in excessive algae growth and reduce water quality.
The Importance of Maintaining River Ecosystem Quality
This study highlights the importance of maintaining the quality and diversity of the river environment to ensure the survival of fish species. By understanding the relationship between fish diversity and environmental factors, appropriate conservation steps can be taken to protect the Peusangan river ecosystem. Further research is needed to monitor changes that may occur and to develop a sustainable management strategy to protect this natural wealth.
Conclusion
In conclusion, this study demonstrates the significance of fish diversity in the Peusangan River and its relationship with environmental factors. The findings of this study provide valuable insights into the importance of maintaining the quality and diversity of the river environment. By taking appropriate conservation steps, we can protect the Peusangan river ecosystem and ensure the survival of fish species.
