National Workshopcum-Training on Bldnformaticr and Information Management in Aquaculture
The long term management plan can be prepared based on the remote sensing
data supported by ancillary data for habitat protection tourist attraction and eco
development for the livelihood of the people. "Nal Sarovar" of Gujarat, India was
monitored with the help of remote sensing for waterfowl habitat management.
14.5 Management of resource wise and location wise data
Assessment of fisheries resources and estimation of production are the most
required research area. Time series data of various resources (like estuaries,
reservoirs floodplain wetland) at various level (national, state and district) are
being considered for this purpose. Creating this database in vector GIs has got
many advantage in understanding not only temporal trends in fisheries growth
but also gives spatial patterns. Further tool GIs gives will be useful in mapping
these trends.
Now more than ever, decision makers at all levels need an increasing amount of
information to help them understand the possible outcomes of their decision by
integrating the data from different sources and types. Due to integration various
statistical tools its give more liberty to decision maker and researchers to analyze
the data.
14.6 Development of Inventory
In the fisheries sector of India, to develop a proper inventory is quite
challengeable and Herculean task. The Indian estuaries have tremendous
potential but production is quite below the predicted one. Due to lack of catch
and inventory data the assessment of production became very difficult. By
creating various thematic map based on biomass, salinity, mesh/Gear, craft and
historical catch data its became easy to analyze and predict the production. Land
use pattern, change in land use pattern, sediment deposition all can be
monitored and quantified with the application RS and GIs. Even though this
technology were used by Carrie Smith and others for linkage between change in
estuarine vegetation and salinity. They found GIS and aerial photographs are
very much useful for mapping of estuarine vegetation.
GIs is useful in assembling of wide ranges of data sources. Readily available
sources of GIs data such as Coastline political boundaries are frequently used
data. Many time Census data also used in GIs for analysis. Land use / land cover
is either obtained from previous compilation or interpret from satellite data.
Catchments boundaries based on DEM or delineated from relief maps. GIS also
use available data to generate Information like rainfall and runoff.
Water body information system of West Bengal that was developed at CIFRI also
used the RS data (LISS 111) and GIS and found for preparing inventory of water
bodies RS data and GIs are very much'useful. This information system able to
give the spatial information (latitude longitude nearest village block district water
area and shape) of water bodies which have the water area more then 10 ha.
14.7 Monitoring of mangrove forest
Mangrove forests form one of the primary coastal ecosystems in the tropical and
subtropical region of the world. They are biologically diverse and have therefore
