Fisheries Data Mapping Center.

The Department, accordingly, initiated a project in the year 2008 with the funding from the State's Plan budget to prepare a GIS enabled digital database and to generate maps of those water bodies on four different scales for District, Block,Gram Panchayat and Mouza for each of the 18 districts with an attribute data baseattached with respective water bodies by application of Remote SensingTechnology. Thereafter, in the year 2009, the project was included as one of the components named as 'Mapping of smaller water bodies and development of GIS based Fisheries Management System' under the Central Sector Scheme "Strengthening of database and development of GIS for the fisheries sector" by theGovt. of India in the Ministry of Agriculture, Department of Animal Husbandry, Dairying and Fisheries with 100% central assistance. The project started in the year 2008 with setting up of a satellite image interpretation lab and a server system to store the spatial data with associated attribute database.


Core Activities

(i) Identification of all water bodies measuring 5 Cottah (0.08 acre) and above in the rural areas and all water bodies measuring one Cottah (0.016 acre) and above in the municipal areas in the entire State of West Bengal.

(ii) Generation of digital water body maps for Mouza, Gram Panchayat, Block and District on the scale of 1:4000, 1:10000, 1:25000 to 1:40000 and 1:150000 to 1:250000 respectively. For municipal areas mapping scale is 1:4000 or 1:5000.

(iii) Creation of a GIS enabled inventory and database of all water bodies.

Allied Activities :
(iv) Creation of an inventory for all fishery related infrastructures like road and railway networks, fishermen's habitats, fish landing centers and fishing harbours, fish markets, ice plants, hatcheries etc.

(v) Development of GIS application by linking spatial database and non-spatial or attribute data and hosting the same on the web.
At the onset the water bodies and other features like roads, rail lines etc. were identified and digitized mostly from archived geo-referenced multi-spectral digital image of 0.6 meter spatial resolution generated by Quick Bird satellite and 0.5 meter spatial resolution taken by World View II satellite.

(i) Water body mapping complain for All the 18 districts and the areas under the Kolkata Municipal Corporation first by the use of Quick Bird satellite image and thereafter, updated using image of World View II.

(ii) The maps of Districts, Blocks, Gram Panchayats and Mouzas showing four different layers, viz., administrative boundaries, water bodies, habitation patch and road and railway networks have been completed.

(iii) About 19 lakh of impounded water bodies of size 0.08 acre and above comprised in ponds/tanks, beel, baor, ox-bow lakes, reservoirs, etc. have been identified and digitally mapped with their attributes.

(iv) With this work, a geo-referenced base map containing the administrative boundaries upto the Mouza level, all open source water resources, roads & railway networks for all the districts have been prepared by other Departments for use and value addition.

(v) Watershed maps of some blocks in the districts of Purulia, Bankura and a part of Paschim Medinipur on the scale of 1: 30,000 have been prepared showing potential sites for construction of check dams.

(vi) In the three hill sub-divisions of Darjeeling district the work of mapping of Jhora Fisheries (Cold Water Fisheries) and preparation of a comprehensive database for such tiny water bodies (even 150 sft. in area), never attempted before anywhere in the country, has been taken up. So far four blocks out of eight have been completed for 04 blocks out of 08.

(vii) GIS data for the districts of Purba Medinipur, Paschim Medinipur, Bankura and Purulia have been web hosted.


Web based availability of GIS maps to the district fishery offices and fishery co-operatives will improve decision making process in a decentralized set up thereby creating a scenario of efficient management.

(i) A comprehensive effort to increase fish production through proper planning needs such a GIS based map of the water body resources. Output of this project is essential in the present context for sustainable use of water resources.

(ii) The use of co-operative fish farming may be an alternative opportunity for the unemployed rural people and will generate a viable income source for uplifting the rural economy.

(iii) The establishment of fish-feed production industry will generate additional employment opportunities. Last but not the least, in appreciation of this work done through this project, two internationally reputed organizations namely Hexagon and Geo-spatial World Forum published an article in the form of case study in their online magazine.
