EO for Fisheries & Aquaculture
EO technologies can offer valuable data on oceanographic and environmental conditions that directly affect marine life and aquaculture operations.
Sustainable Fishery Management
Ocean Surface Temperature Monitoring: EO satellites can monitor sea surface temperatures, which significantly influence marine habitats and the distribution of fish populations. By tracking temperature changes, fisheries managers can predict fish migration patterns, optimize fishing efforts, and reduce bycatch. This data helps in maintaining the balance of marine ecosystems by preventing overfishing in sensitive areas.
Catch Optimization: Habitat mapping for fish species using EO data, combined with weather data and other relevant parameters like biogeochemical analyses, topography, and ocean currents. This application is pivotal for determining the optimal timing, location, and methods for fishing activities, thereby optimizing the catch.
Chlorophyll Concentration Mapping: Satellites equipped with sensors to detect chlorophyll can provide data on phytoplankton concentrations, a primary food source for many fish species. This information is crucial for understanding the basis of the marine food web and identifying fertile fishing grounds, leading to more targeted and efficient fishing practices.
Genetic Diversity and Stock Improvement: EO data, combined with genetic information, can help in understanding the genetic diversity of fish populations in the wild. This knowledge supports the development of breeding programs that improve stock resilience to diseases and environmental changes, enhancing aquaculture productivity and sustainability.
Climate Impact Modelling: Integrating EO data with climate models offers insights into the future impact of climate change on marine ecosystems and fisheries. This information is crucial for developing strategies to ensure the resilience of fish stocks and aquaculture operations to changing oceanic conditions.
Aquaculture Site Selection
Water Quality Assessment: EO technologies can assess water quality parameters such as turbidity, nutrient levels, and pollutants near coastal aquaculture sites. High-resolution imagery helps in identifying areas with optimal conditions for aquaculture and monitoring changes in water quality over time, ensuring the health and growth of cultured species. Hyperspectral imaging from spaceborne platforms can provide detailed information on water quality by capturing data across a wide range of wavelengths. This technology can identify specific indicators of water quality such as phytoplankton blooms, sediment concentration, and pollutants with unprecedented precision. For aquaculture, this means the ability to monitor and manage the health of aquatic environments in real-time, enabling proactive responses to potential issues.
Bathymetric Surveys: Satellite imagery can be used to conduct bathymetric surveys of potential aquaculture sites, identifying underwater topography and suitable depths for fish and shellfish farming. This information is vital for designing aquaculture infrastructure that minimizes environmental impact and maximizes production efficiency.
Environmental Protection and Regulation Compliance
Synthetic Aperture Radar (SAR) for Marine Environment Monitoring: SAR technology can penetrate cloud cover and operate irrespective of daylight, providing consistent monitoring capabilities for marine and coastal environments. This can be particularly useful for mapping and monitoring aquaculture sites, detecting oil spills, and observing ice conditions in fishing areas. SAR data can also assist in detecting changes in coastal topography that affect fish habitats and aquaculture sites.
Habitat and Biodiversity Conservation: EO data supports the mapping and monitoring of critical habitats such as coral reefs, mangroves, and seagrass beds that are vital for the lifecycle of many marine species. Continuous monitoring allows for the assessment of the impact of aquaculture operations on these ecosystems, aiding in the development of strategies for their protection and restoration.
Illegal, Unreported, and Unregulated (IUU) Fishing Detection: Advanced algorithms and imaging technologies can detect vessels and activities that indicate IUU fishing. By integrating EO data with Automatic Identification System (AIS) signals, authorities can identify and track illegal fishing operations, enforce regulations, and protect marine resources.
Climate Change Adaptation and Disaster Risk Reduction
