Diversity and Distribution of Bivalvia and its Relation to Physical-Chemical Factors in the Waters of Labu Beach, Deli Serdang Regency

Introduction

Labu Beach, located in Deli Serdang Regency, North Sumatra, is a coastal area that has been the subject of research to study the diversity and distribution of Bivalvia and its relationship with physical-chemical factors of water. This study aims to provide an overview of the diversity and distribution of Bivalvia in the waters of Labu Beach, as well as its relationship with the physical-chemical factors of water. The research was conducted in January to March 2008, by taking samples from three different observation stations.

Methodology

The research was conducted using the purposive random sampling method to determine the sampling point. Bivalvia samples were taken using claws and identified with the help of internet sites. The results of laboratory measurements showed that the physical-chemical factors of sea water in the waters of Labu Beach are within a safe threshold and suitable for bivalvia life, based on sea water quality standards determined by the State Minister of Environment with Decree No. 51 of 2004.

Results

The study found five types of Bivalvia, consisting of five families, three orders, one class, and one phylum. These types are:

Anadara granosa
Andrana Patagonica
Hecuba Scortum
Mactra Janeiroensis
Tellina EXERYTHRA

Anadara granosa has the highest population density among other types, reaching 642,2338 ind/m² at station III. Conversely, Tellina EXERYTHRA has the lowest population density of 21,8150 IND/m² at Station I. Bivalvia Diversity Index in Labu Coastal Waters ranges from 0.5028-0,8680. Based on the calculation of the distribution index, it can be concluded that bivalvia distribution in the region tends to be in groups.

Correlation Analysis

Correlation analysis with the Pearson test shows that orthophosphate levels are positively correlated to bivalvia diversity. This means, the higher the level of orthophosphate in water, the higher the diversity of bivalvia in the waters of Labu Beach.

Discussion

The results of this study provide an overview of the diversity and distribution of Bivalvia in the waters of Labu Beach, as well as its relationship with the physical-chemical factors of water. This finding is important to understand bivalvia ecology in the region and can be used as a basis for sustainable conservation and management of marine resources.

Important Points to Consider

High orthophosphate levels highly correlated with bivalvia diversity. This shows that the availability of nutrition, especially phosphate, plays an important role in supporting Bivalvia's life.
Group Bivalvia Distribution indicates the existence of specific environmental factors at each observation station. This needs to be further investigated to understand the factors that influence bivalvia distribution.
Relatively low diversity of bivalvia in the waters of Labu Beach needs to be a concern. This can be caused by factors such as pollution, excessive fishing, and climate change.

Conclusion

Further research is needed to study the dynamics of bivalvia populations in the waters of the Pabu coast, as well as the influence of anthropogenic factors on bivalvia diversity and distribution in the region.

Recommendations

Based on the results of this study, the following recommendations are made:

Monitoring of bivalvia populations should be conducted regularly to understand the dynamics of bivalvia populations in the waters of Labu Beach.
Conservation and management of marine resources should be implemented to protect the bivalvia populations and their habitats.
Research on the influence of anthropogenic factors on bivalvia diversity and distribution should be conducted to understand the impact of human activities on bivalvia populations.

Future Research Directions

Understanding the factors that influence bivalvia distribution in the waters of Labu Beach.
Studying the impact of human activities on bivalvia populations and their habitats.
Developing effective conservation and management strategies for bivalvia populations and their habitats.

By conducting further research in these areas, we can gain a better understanding of the diversity and distribution of Bivalvia in the waters of Labu Beach, as well as the factors that influence their populations and habitats. This knowledge can be used to develop effective conservation and management strategies for bivalvia populations and their habitats, and to protect the marine ecosystem of Labu Beach.
Frequently Asked Questions (FAQs) about Bivalvia Diversity and Distribution in Labu Beach Waters

Q: What is Bivalvia?

A: Bivalvia is a class of marine mollusks that includes clams, mussels, oysters, and scallops. They are characterized by their two hinged shells that can be opened and closed.

Q: What is the significance of studying Bivalvia diversity and distribution in Labu Beach waters?

A: Studying Bivalvia diversity and distribution in Labu Beach waters is important because it can provide insights into the health of the marine ecosystem and the impact of human activities on the environment. Bivalvia are an important food source for many marine animals, and changes in their populations can have cascading effects on the entire ecosystem.

Q: What are the physical-chemical factors that affect Bivalvia diversity and distribution in Labu Beach waters?

A: The physical-chemical factors that affect Bivalvia diversity and distribution in Labu Beach waters include water temperature, salinity, pH, and nutrient levels. These factors can influence the availability of food and habitat for Bivalvia, and can also affect their ability to survive and reproduce.

Q: What is the relationship between orthophosphate levels and Bivalvia diversity?

A: The study found that orthophosphate levels are positively correlated with Bivalvia diversity. This means that higher levels of orthophosphate in the water are associated with higher diversity of Bivalvia in the waters of Labu Beach.

Q: What are the implications of the relatively low diversity of Bivalvia in Labu Beach waters?

A: The relatively low diversity of Bivalvia in Labu Beach waters is a concern because it may indicate that the marine ecosystem is under stress. This can be caused by factors such as pollution, excessive fishing, and climate change.

Q: What are the recommendations for conservation and management of Bivalvia populations in Labu Beach waters?

A: The recommendations for conservation and management of Bivalvia populations in Labu Beach waters include:

Monitoring of Bivalvia populations to understand their dynamics and trends
