Abundance and Pattern of Pinna Bicolor (Pinna Bicolor) in Seagrass Ecosystems in Poncan Gadang Island Waters, Sibolga City, North Sumatra Province
Introduction
The seagrass ecosystem located in the waters of Poncan Gadang Island, Sibolga City, is known to have abundant biological resources. One of the bivalve organisms found in this region is the ax (pinna bicolor). Ax shells are a type of mollusks that have a triangular, thin, and tapered shell shape to the substrate. This shell is included in the large bivalve group, with a length of the shell can reach 30 to 40 cm. Aside from being an important component in the ecosystem, ax shells also function as a bioindicator of water quality. Understanding the abundance and pattern of pinna bicolor in seagrass ecosystems is crucial for managing and preserving biological resources in this region .
Background
Seagrass ecosystems are known to provide a habitat for a variety of marine species, including bivalves such as pinna bicolor. These ecosystems are also important for maintaining water quality and supporting fisheries. However, seagrass ecosystems are facing threats from human activities such as coastal development, pollution, and overfishing. Therefore, it is essential to study the abundance and pattern of pinna bicolor in seagrass ecosystems to understand the dynamics of population and the factors that influence their abundance and distribution .
Methodology
This study aims to determine the abundance and pattern of the distribution of ax (pinna bicolor) in the waters of Poncan Gadang Island. Research was conducted in September 2021 in the Pasar Bertang area, Sibolga Kota District. The sampling method used is the quadrant transect method with three research stations. Then, the abundance and pattern of the ax shell distribution is calculated based on the data obtained. The quadrant transect method is a widely used method for studying the distribution of marine species, and it provides a reliable estimate of abundance and pattern .
Results
The results showed that the abundance of ax shells varies with a value between 1.3 to 2.33 individuals per m². This indicates that the existence of ax shells is quite good in the seagrass ecosystem. In addition, the value of the ax shell distribution index in the three research stations ranges from 1.14 to 2.18. This range of values indicates a group distribution pattern, which means that individuals of the ax shells are not spread evenly, but are more commonly found in certain groups. The group distribution pattern can be caused by several factors, including food availability, substrate conditions, and interactions with other species in the ecosystem .
Discussion
The group distribution pattern of pinna bicolor in seagrass ecosystems can be influenced by several factors, including food availability, substrate conditions, and interactions with other species in the ecosystem. The seagrass ecosystem provides an ideal habitat for pinna bicolor to grow and develop, because the existence of seagrass can provide protection and reduce strong currents. In addition, pinna bicolor can use detritus that comes from seagrass as their food source. Understanding the factors that influence the abundance and distribution of pinna bicolor is crucial for managing and preserving biological resources in this region .
Conclusion
From the results of this study, it can be concluded that the ax (pinna bicolor) has a significant role in seagrass ecosystems in the waters of Poncan Gadang Island. Further research is needed to understand the dynamics of population and the factors that influence the abundance and distribution of ax shells. Through a deeper understanding, we can manage and preserve biological resources in this region better, so that the ecosystem can continue to function properly and provide benefits to the local community. The results of this study can be used as a basis for developing conservation and management strategies for seagrass ecosystems in this region .
Recommendation
Based on the results of this study, it is recommended that further research be conducted to understand the dynamics of population and the factors that influence the abundance and distribution of ax shells. In addition, conservation and management strategies should be developed to protect and preserve seagrass ecosystems in this region. The local community should also be involved in the conservation and management of seagrass ecosystems, as they have a crucial role to play in maintaining the health of these ecosystems .
Limitation
This study has several limitations, including the small sample size and the limited number of research stations. Further research is needed to confirm the results of this study and to understand the dynamics of population and the factors that influence the abundance and distribution of ax shells .
Future Research
Future research should focus on understanding the dynamics of population and the factors that influence the abundance and distribution of ax shells. In addition, conservation and management strategies should be developed to protect and preserve seagrass ecosystems in this region. The local community should also be involved in the conservation and management of seagrass ecosystems, as they have a crucial role to play in maintaining the health of these ecosystems .
