Abstract

The biological management of water hyacinth (Eichhornia crassipes) through Neochetina spp. was studied in the Panchaganga River, Kolhapur, India, where extensive infestations threatened ecological balance and human activities. Five sites along the river were monitored for six months after the introduction of Neochetina weevils. Initial water hyacinth cover averaged 85%, declining to 51% post-intervention, reflecting a 40% reduction. Water quality parameters showed significant improvements, with dissolved oxygen levels increasing by 25% and a slight pH rise indicating favorable ecosystem conditions. Biodiversity evaluations indicated a rise in species diversity indices and the resurgence of native fish species. Statistical analysis confirmed a strong correlation (R² = 0.85) between weevil density and biomass reduction. Visual and spatial analyses supported these findings, showing reduced hyacinth density and improved river navigability. This research demonstrates Neochetina spp. as effective agents for sustainable water hyacinth management, emphasizing their role in restoring ecological health in impacted river systems.

Conclusion

In conclusion, applying Neochetina spp for biological control presents a sustainable and environmentally friendly solution to the persistent challenge of water hyacinth infestations in the Panchaganga River. The positive outcomes observed underscore the efficacy of biological methods in restoring and maintaining the ecological integrity of aquatic ecosystems impacted by invasive species. Going forward, ongoing monitoring and integrated management practices will be essential to sustain these gains and support a resilient river ecosystem for future generations.

For long-term success, it is recommended to combine biological control with periodic mechanical removal to manage the remaining water hyacinth biomass. Additionally, community engagement initiatives should be implemented to raise awareness and promote sustainable river management practices. By combining these strategies, the health and resilience of the Panchaganga River ecosystem can be effectively restored and maintained.
