Aerial drones further enhance this capability by offering detailed, localized surveys of fishing zones, identifying environmental changes and fish congregation points with minimal disturbance.
b. Real-time monitoring of fish stocks and environmental conditions
Sensors deployed across marine protected areas gather continuous data on fish abundance, water quality, and temperature. This information feeds into dynamic models that inform quota setting and seasonal closures, helping prevent overfishing. For example, integrated monitoring systems in the North Atlantic have contributed to a 15% increase in sustainable catch levels over five years.
c. The role of machine learning in predicting fish behavior and migration
Machine learning algorithms process vast datasets to uncover patterns in fish movement, spawning behavior, and environmental preferences. Researchers have developed models that predict migration routes of Atlantic salmon with over 90% accuracy, enabling timely management actions and resource allocation.
4. The Rise of Smart Gear and Equipment
Technological advances have led to the development of intelligent fishing gear designed to reduce bycatch, improve data collection, and lessen environmental impacts.
