Satellite Technology Interventions
Remote Sensing Technology is used for fishery resource management, their
conservation and exploitation. Thus, it helps in making more informed management
decisions, in adjusting fishing efforts to conditions of fishing grounds and/or
stocks, ensuring sustainable exploitation of marine living resources.
Application of remote sensing in estimating fishery resources can be assisted by
the measurement of the concentration of ' chlorophyll pigments. It is considered
as an index of biological productivity and it can be related to fish production.
Today, SST (Sea Surface Temperature) maps the tuna fishing fleets. Satellites
can also assist the fishing industry in many ways other than locating of fish
such as a) Search and rescue operations: The satellite N0AA-8 carries a special
sensor, SARSAT (Search and Rescue Satellite Tracking). b) Radar altimeter:
measures wave height and the micro topography of the ocean surface c) Synthetic
Aperture Radar (SAR) : measures wave length and direction radar d) Scatterometer
SASS: measures near surface wind speed over the oceans in all weather conditions
e) Weather reports: Environmental satellites such as NOAA, GOES or METEOSAT can
provide weather information. f) helps in identifying Potential Fishing Zones (PFZ)
based on chlorophyll concentration & sea surface temperature (SST) g) In
providing information on temporal & spatial changes in area under aquaculture,
mangrove areas, coral reef mapping.
