The Influence of the Baro Raya Irrigation Development on the Diversity of Fish Species in the River in TK II Pidie Regency

Introduction

The construction of the Baro Raya irrigation project in Pidie Regency has been a significant development in the region, aimed at increasing agricultural productivity and improving the livelihoods of local communities. However, this project has also had a profound impact on the diversity of fish species in the affected river. This study aims to evaluate the extent to which the irrigation project affects the fish population, density index, diversity index, and common fish species index along the Baro Raya irrigation river.

Methodology

To get accurate data, this research uses primary data from field observations in the Baro Raya irrigation river and interviews with the local community. The research method used is a complete random design, and to determine the fish density index, the * capture-recapture method * or Lincoln-Peterson is applied. Meanwhile, the fish diversity index is measured using the Shannon-Wiener (H) method and the fish similarity index uses the proportional similarity method.

Results

The results of the analysis show that the construction of the Baro Raya irrigation project significantly affects the population of fish species. On a scale of 1% and 0.5%, the value of F arithmetic (6.64 and 13.99) is greater than the value of F table (3.23 and 4.84), shows a significant impact. In addition, the construction of this project also affects the density of fish species, with the calculated F of 15.79, far higher than the F table on a scale of 1% and 0.5% (4.54 and 7.71).

Although the impact on the population and density of fish is very real, this project seems to have less effect on the physical and chemical changes of water in the area. This study found that although there was an influence on the physics/chemistry of water, its effect on the diversity index and the similarity index of fish species in river flow was not significant. This can be seen from the results that indicate that F count (1,00 and 0.22) is still smaller than the F table on the same scale.

Discussion

From the results of the study it was also revealed that the loss of the habitat of the Paya-Paya along the river became one of the negative impacts of the development of this irrigation, where as many as 12 Paya-Paya was reported to have disappeared. The loss of this habitat can contribute to changes in local ecosystems, which in turn will affect the existence and diversity of fish species in the area.

The construction of the Baro Raya irrigation project has a positive impact on the use of agricultural land, but the impact on the diversity of fish species in the river flow is very complex. This study suggests the need for wise and sustainable management to maintain the balance of river ecosystems while still meeting the needs of agricultural development. It is important for related parties to consider environmental aspects in every development project so that the benefits produced can be felt holistically by the community and ecosystems.

Conclusion

In conclusion, the construction of the Baro Raya irrigation project has a significant impact on the diversity of fish species in the river flow. The loss of habitat and changes in local ecosystems can contribute to the decline of fish species, which can have a ripple effect on the entire ecosystem. Therefore, it is essential to adopt a sustainable and environmentally-friendly approach to development projects to ensure that the benefits are shared by all stakeholders.

Recommendations

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

Conduct a thorough environmental impact assessment before embarking on any development project to identify potential risks and mitigate them.
Implement sustainable management practices to maintain the balance of river ecosystems and ensure the long-term health of fish populations.
Involve local communities in the decision-making process to ensure that their needs and concerns are taken into account.
Monitor and evaluate the impact of development projects on the environment and adjust management practices accordingly.

By adopting these recommendations, we can ensure that development projects are carried out in a way that balances economic, social, and environmental needs, and that the benefits are shared by all stakeholders.

Q: What is the Baro Raya irrigation project, and what is its purpose?

A: The Baro Raya irrigation project is a development project aimed at increasing agricultural productivity in Pidie Regency. The project involves the construction of canals, dams, and other infrastructure to supply water to agricultural areas.

Q: How does the Baro Raya irrigation project affect the diversity of fish species in the river?

A: The construction of the Baro Raya irrigation project has a significant impact on the diversity of fish species in the river. The project has led to changes in the physical and chemical properties of the water, which can affect the existence and diversity of fish species.

Q: What are the main factors that contribute to the decline of fish species in the river?

A: The main factors that contribute to the decline of fish species in the river include the loss of habitat, changes in water quality, and the introduction of non-native species.

Q: What is the impact of the loss of habitat on fish species?

A: The loss of habitat can contribute to the decline of fish species by reducing the availability of food, shelter, and breeding grounds. In the case of the Baro Raya irrigation project, the loss of Paya-Paya habitat has been reported to have affected the existence and diversity of fish species in the area.

Q: What can be done to mitigate the impact of the Baro Raya irrigation project on fish species?

A: To mitigate the impact of the Baro Raya irrigation project on fish species, it is essential to adopt sustainable management practices that maintain the balance of river ecosystems. This can include measures such as the creation of fish-friendly habitats, the implementation of water quality management practices, and the introduction of non-native species that are compatible with the existing ecosystem.

Q: What is the role of local communities in the management of the Baro Raya irrigation project?

A: Local communities play a crucial role in the management of the Baro Raya irrigation project. They can provide valuable insights into the impact of the project on the environment and can help to identify solutions to mitigate any negative effects.

Q: What are the long-term consequences of the Baro Raya irrigation project on the environment?

A: The long-term consequences of the Baro Raya irrigation project on the environment are still unclear. However, it is essential to monitor and evaluate the impact of the project on the environment to ensure that any negative effects are mitigated.

Q: What can be done to ensure that the benefits of the Baro Raya irrigation project are shared by all stakeholders?

A: To ensure that the benefits of the Baro Raya irrigation project are shared by all stakeholders, it is essential to adopt a participatory approach to development that involves local communities, government agencies, and other stakeholders in the decision-making process.
