Understanding the Baung Fish Food Habits in the Bingai River, North Sumatra Province

Introduction

The Bingai River in North Sumatra Province is home to a diverse range of aquatic life, including the baung fish (Mystus nemurus C.V). As a predator, the baung fish plays a crucial role in maintaining the balance of the ecosystem. However, to ensure the sustainability of the baung fish population, it is essential to understand their food habits and preferences. This article aims to provide an in-depth analysis of the baung fish food habits in the Bingai River, highlighting the types of natural food consumed, the availability of natural feed, and the factors that affect their diet.

Research Methodology

The research on the baung fish food habits was conducted in the Bingai River from June to August 2014. The study aimed to identify the types of natural food consumed by the baung fish, the availability of natural feed in the river, and to observe the general condition of the waters. The stomach contents of the fish were analyzed using the preponderance index, which is a method used to determine the proportion of each food item in the stomach contents.

Analysis of Baung Fish Food Habits

The analysis of the stomach contents of the baung fish revealed that they consume a diverse range of food items, including 8 species of fish, plant fiber, Thiara scabra, Planaria sp., Nodilittorina Pyramidalis, Faunus Ater, insect remnants, and several other unidentified parts. The data obtained from the analysis showed that small fish are the main food source for the baung fish, while plant fiber functions as a complementary food. Other types of food, such as Planaria sp., Thiara Scabra, Nodilittorina Pyramidalis, and Faunus Ater, are considered additional feed.

Interestingly, the baung fish have selective properties when it comes to the food they consume. The electivity index or index (E) indicates that Planaria sp. is the most popular type of benthos feed for the baung fish compared to other types of benthos. This selective behavior is a reflection of the adaptation of the baung fish to their environment, where they have a strong preference for food available in their habitat.

Factors Affecting Baung Fish Diet

The availability of natural feed, water quality conditions, and pressure from other predators are some of the factors that affect the diet of the baung fish. A healthy aquatic environment and rich in natural foods supports a stable and productive baung fish population. Therefore, monitoring of water conditions and the existence of benthos is very important for the sustainability of this ecosystem.

Conclusion

This research provides an important insight into the ecology of the baung fish in the Bingai River. By understanding the eating habits and choices of the baung fish feed, the steps of protection and management of aquatic resources can be done to maintain the balance of the ecosystem and the sustainability of the baung fish population in the future. The findings of this study highlight the importance of preserving the biodiversity of the Bingai River and its ecosystem, which is essential for the long-term sustainability of the baung fish population.

Recommendations

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

Monitoring of water conditions: Regular monitoring of water conditions, including water quality and the existence of benthos, is essential for the sustainability of the baung fish population.
Protection of natural feed: The protection of natural feed, including small fish and other food sources, is crucial for maintaining the balance of the ecosystem.
Management of aquatic resources: The management of aquatic resources, including the regulation of fishing activities and the protection of habitats, is essential for maintaining the sustainability of the baung fish population.

By implementing these recommendations, it is possible to maintain the balance of the ecosystem and ensure the long-term sustainability of the baung fish population in the Bingai River.

Future Research Directions

Future research directions include:

Long-term monitoring of baung fish population: Long-term monitoring of the baung fish population is essential for understanding the dynamics of the ecosystem and the impact of human activities on the population.
Study of the impact of climate change: The study of the impact of climate change on the baung fish population and the ecosystem is essential for understanding the potential risks and challenges facing the population.
Development of conservation strategies: The development of conservation strategies, including the protection of habitats and the regulation of fishing activities, is essential for maintaining the sustainability of the baung fish population.

By addressing these research directions, it is possible to gain a deeper understanding of the ecology of the baung fish in the Bingai River and to develop effective conservation strategies for maintaining the sustainability of the population.
