Galician Scientists Use Drones to Revolutionize Shellfish Farming

Drones Take Flight to Boost Shellfish Production in Pontevedra Estuary A groundbreaking study in the Ría de Pontevedra, Spain, is leveraging drone technology to revolutionize clam and cockle cultivation. Researchers are utilizing high-definition aerial photography and thermal imaging to create detailed maps of the seabed, providing crucial insights into water temperature and currents. This data, combined with on-the-ground and boat-based sampling of sediments, allows scientists to pinpoint environmental factors that directly influence bivalve growth and productivity. "Variables like topography, chlorophyll levels, and temperature significantly affect different shellfish species," explains Bruno Míguez, an analyst at Telespazio Ibérica and a key participant in the Marisdrone study. The research also involves Marislab and Envirosub, collaborating with institutions such as the CSIC and the University of Vigo, alongside local shellfish associations. The project's impact extends beyond scientific discovery. Andrés Simón Gómez, a technical assistant at the Campelo fish market, highlights the importance of establishing "standards to ensure the optimal conditions for clam larvae and young clams." This data-driven approach promises to enhance sustainability and increase yields, benefiting both the environment and the local fishing community. Dolores Moreira, president of the Lourizán on-foot shellfish gathering group, notes that "significant changes in tides and currents, and the formation of new sandbanks," are impacting the industry, making this research even more critical. The study's findings will inform the creation of ideal environments for shellfish cultivation in other areas, promoting sustainable practices and safeguarding the future of this vital industry.
