Question: Discuss the potential uses of drone technology in the fisheries and aquaculture sector.

Answer: Drone technology is increasingly transforming the fisheries and aquaculture sectors by providing innovative solutions, boosting productivity, and increasing sustainability in these sectors.

❖ Use of Drone Technology in Fisheries

• Monitoring and Surveillance of Fishing Zones: Drones enable real-time tracking of fish populations and illegal fishing activities, ensuring beneficial conservation and sustainability of the resource. Eg: The Fisheries Survey of India uses drones to monitor marine fisheries, which has led to a reduction in illegal fishing off the west coast of India.

• Disaster Management and Rescue Operations: Drones are used in rescue operations, supply delivery, post-disaster damage assessment, to stranded fishermen during natural or man-made emergencies. E.g.: During Cyclone Taukate (2021), drones were used in coastal areas in Gujarat for emergency assistance and damage assessment.

• Mapping and environmental conservation: Drones help in mapping fishing zones and monitoring coastal habitats, supporting sustainable fishing practices and ecosystems. E.g.: ICAR-CIFT uses drones to survey the condition of mangroves along with fisheries, which contributes to the conservation of coastal ecosystems.

• Fish stock assessment: Drones facilitate stock estimation by accurately assessing fish populations and movements and help prevent overfishing. Japan uses drones to monitor tuna stocks.

• Assist in anti-poaching operations: Drones help officials detect poaching and unauthorized fishing in restricted coastal zones, assisting in patrols to prevent unauthorized poaching.

❖ Use of Drone Technology in Aquaculture

• Feed Management and Stock Assessment: Drones help in proper distribution of pellet feed in aquaculture areas, regular stock assessment, and cost reduction through sustainable uses.

• Disease detection and health monitoring: Drones equipped with multi-spectral sensors can detect early signs of disease or stress in fish populations, enabling timely intervention and treatment. For example, the Marine Products Export Development Authority (MPEDA) uses drones to monitor health-related diseases in aquaculture farms like this one in Kerala.

• Water quality monitoring: Drones provide regular assessment of water quality, which is important for monitoring parameters like temperature, pH and oxygen levels, which are crucial for healthy aquaculture. For example, Andhra Pradesh uses drones to monitor water quality in marine fish farms, which helps in increasing productivity.

• Infrastructure and Asset Monitoring: Drones help improve efficiency by monitoring aquaculture-related facilities, rafts, and tanks.

• Monitoring fish stock behavior in offshore aquaculture farms: Underwater drones monitor fish behavior and enable changes to be made to identify feeding issues. For example, the Norwegian aquaculture sector is using underwater drones to conduct studies to improve its behavior, stock, health, and productivity.

❖ Conclusion

Drone technology is revolutionizing the fisheries and aquaculture sectors through aviation. With monitoring, resource management and operational efficiency, coupled with continuous innovation and support from government policy, this technology is poised to enable sustainable and resilient fisheries ecosystems.
