Morphological and Genetic Analysis of Batak Fish (Tor Soro) in North Sumatra

Introduction

The Batak fish, scientifically known as Tor Soro, is a species of fish that is native to the rivers of North Sumatra, Indonesia. This species has been an important part of the local ecosystem and the cultural heritage of the Batak community for centuries. However, with the increasing demand for fish and the degradation of their natural habitats, the Batak fish population is facing a significant threat to its survival. In this study, we conducted a morphological and genetic analysis of the Batak fish population in North Sumatra to understand their genetic diversity and to identify the potential conservation strategies for this species.

Research Methodology

In this study, we collected fish samples from three different locations in North Sumatra, namely the Bahorok River in Langkat Regency, the Alian Sungai in Toba Samosir Regency, and the Batangtoru River in South Tapanuli Regency. We used the Truss Method to analyze the morphological characteristics of the fish, which involves measuring the length and width of the fish's body and its various parts. The data was then processed using SPSS software version 16 to identify any significant differences in the morphological characteristics of the fish from different locations.

In addition to the morphological analysis, we also conducted a genetic analysis of the Batak fish population using the Random Amplified Polymorphism DNA (RAPD) technique. This technique involves amplifying the DNA of the fish using a set of primers and then analyzing the resulting DNA fragments to identify any genetic variations. The results of the PCR amplification were then analyzed using the Numerical Taxonomy and Multivariate Analysis System (NTSYS) 2.0 program to get a picture of the genetic diversity of the Batak fish population.

Results and Discussion

The results of this study indicate that morphologically and genetically, the Batak fish originating from Batangtoru has a higher genetic closeness with fish from the Alian River compared to fish originating from the Bahorok River. This finding opens a new understanding of genetic relations between fish populations in the North Sumatra region.

The level of diversity identified in this study is very important for the conservation of species and management of fisheries resources. High genetic diversity can help fish to adapt to the changing environment, so it is important for related parties to maintain their natural habitat. The results of this study also highlight the importance of preserving the genetic diversity of the Batak fish population, which is essential for the long-term survival of this species.

Conclusion

In conclusion, this research provides valuable insight into the morphology and genetic diversity of Batak fish in North Sumatra. It was found that there is a genetic relationship that is closer between the population in Batangtoru and Alian, which has important implications for conservation and fisheries management strategies in the region. Through this research, it is hoped that there will be further action to protect and maintain the existence of Batak fish, considering that this species is an important part of the local ecosystem and the cultural Batak community.

Recommendations

Based on the results of this study, we recommend the following conservation and management strategies for the Batak fish population:

Establishment of protected areas: The establishment of protected areas in the rivers of North Sumatra, particularly in the Batangtoru and Alian rivers, is essential for the conservation of the Batak fish population.
Habitat preservation: The preservation of the natural habitat of the Batak fish is crucial for the long-term survival of this species. Efforts should be made to maintain the water quality and prevent pollution in the rivers.
Fisheries management: The management of fisheries resources in North Sumatra should be done in a sustainable manner to prevent overfishing and ensure the long-term survival of the Batak fish population.
Education and awareness: Education and awareness programs should be implemented to raise awareness about the importance of conserving the Batak fish population and the need to protect their natural habitat.

Future Research Directions

This study provides a valuable insight into the morphology and genetic diversity of the Batak fish population in North Sumatra. However, there are still many areas that require further research, including:

Genetic analysis of other fish species: The genetic analysis of other fish species in North Sumatra can provide valuable information about the genetic diversity of fish populations in the region.
Morphological analysis of other fish species: The morphological analysis of other fish species in North Sumatra can provide valuable information about the morphological characteristics of fish populations in the region.
Conservation and management strategies: Further research is needed to develop effective conservation and management strategies for the Batak fish population.

Limitations of the Study

This study has several limitations, including:

Limited sample size: The sample size of this study was limited, which may not be representative of the entire Batak fish population in North Sumatra.
Limited geographic scope: This study was conducted in only three locations in North Sumatra, which may not be representative of the entire region.
Limited time frame: This study was conducted over a limited time frame, which may not capture the full range of genetic and morphological variations of the Batak fish population.

Conclusion

In conclusion, this research provides valuable insight into the morphology and genetic diversity of Batak fish in North Sumatra. The results of this study highlight the importance of preserving the genetic diversity of the Batak fish population, which is essential for the long-term survival of this species. We recommend the establishment of protected areas, habitat preservation, fisheries management, and education and awareness programs to conserve the Batak fish population. Further research is needed to develop effective conservation and management strategies for this species.
