The Relationship Between Water Quality and the Habits of Batak Fish Food (Tor Douronensis) in the Waters of the Asahan River, North Sumatra

Introduction

The Asahan River in North Sumatra is a vital water source that supports a diverse range of aquatic life, including the Batak fish (Tor douronensis). This fish species is an important part of the ecosystem, and its habits and feeding patterns play a crucial role in maintaining the balance of the river's ecosystem. However, the relationship between water quality and the habits of Batak fish is not well understood, and this study aims to investigate this relationship.

Background

The Batak fish (Tor douronensis) is a species of fish that is native to the Asahan River in North Sumatra. It is a popular food fish in the region, and its population is an important indicator of the river's health. The Batak fish is a carnivorous species that feeds on a variety of organisms, including algae, plankton, and small invertebrates. The fish's feeding habits are influenced by various factors, including water temperature, light intensity, and water chemistry.

Methodology

This study used a combination of field observations and laboratory analysis to investigate the relationship between water quality and the habits of Batak fish. Fish sampling was conducted using electrofishing and mesh techniques, and the contents of the fish's stomach were analyzed using a volumetric method. The results of the analysis were used to determine the types of organisms that the Batak fish feeds on and the relationship between water quality and the fish's feeding habits.

Results

The results of this study showed that the Batak fish (Tor douronensis) had an allometric growth pattern, indicating that the fish's growth rate is influenced by various factors, including water quality. The analysis of the contents of the fish's stomach revealed 42 types of organisms, with Cymbella (56.32%), Navicula (46.65%), Thiothrix (44.25%), and Ulothrix (76.21%) being the main food sources of the Batak fish.

The results also showed a significant correlation between various parameters of water quality and the habits of eating Batak fish. Temperature showed a high correlation with Thiothrix, while brightness was also strongly correlated with the same type of organism. In addition, the intensity of light had a very strong correlation with Navicula, and the current water currents were highly correlated with the same type of organisms.

Water chemical parameters such as pH, DO (Dissolved Oxygen), BOD5 (BioChemical Oxygen Demand), NO3 (nitrate), and PO4 (phosphate) also showed a significant correlation to the organism in the contents of the stomach of the Batak fish. For example, pH correlated very strongly with Cymbella, while DO and BOD5 were strongly correlated with Navicula. Nitrate (NO3) and high phosphate (PO4) correlated with Thiothrix, indicating that good water conditions strongly support the growth of various organisms that are the source of the food of Batak fish.

Discussion

The results of this study indicate that the condition of the Asahan River waters is relatively good and supports the growth and habits of eating Batak fish (Tor douronensis). The study's findings suggest that the relationship between water quality and the eating habits of Batak fish is an important aspect in managing water resources in North Sumatra. The study's results also highlight the importance of maintaining good water quality to support the sustainability of the Batak fish population in the river.

Conclusion

In conclusion, this study has provided new insights into the relationship between water quality and the habits of Batak fish (Tor douronensis) in the waters of the Asahan River, North Sumatra. The study's findings suggest that good water conditions are essential for the growth and survival of Batak fish, and that maintaining good water quality is crucial for the health of ecosystems and the survival of species that depend on it. Further research is needed to investigate other factors that affect fish habitat and to develop more effective conservation strategies.

Recommendations

Based on the study's findings, the following recommendations are made:

Monitoring of water quality: Regular monitoring of water quality parameters such as pH, DO, BOD5, NO3, and PO4 is essential to ensure that the Asahan River waters remain in good condition.
Conservation of Batak fish: Conservation efforts should be made to protect the Batak fish population in the Asahan River, including the establishment of protected areas and the implementation of sustainable fishing practices.
Research on fish habitat: Further research is needed to investigate other factors that affect fish habitat and to develop more effective conservation strategies.
Community engagement: Community engagement and education are essential to raise awareness about the importance of maintaining good water quality and the conservation of Batak fish.

Limitations

This study has several limitations, including:

Limited sampling: The study's sampling was limited to a single location in the Asahan River, and further research is needed to investigate the relationship between water quality and the habits of Batak fish in other locations.
Limited analysis: The study's analysis was limited to a single type of organism, and further research is needed to investigate the relationship between water quality and the habits of Batak fish with other types of organisms.
Limited data: The study's data were limited, and further research is needed to collect more data on the relationship between water quality and the habits of Batak fish.

Future Research Directions

Future research directions include:

Investigating other factors that affect fish habitat: Further research is needed to investigate other factors that affect fish habitat, including water temperature, light intensity, and water chemistry.
Developing more effective conservation strategies: Further research is needed to develop more effective conservation strategies for the Batak fish population in the Asahan River.
Investigating the relationship between water quality and the habits of other fish species: Further research is needed to investigate the relationship between water quality and the habits of other fish species in the Asahan River.
