ABSTRACT
A GIS based study was undertaken to map the available resources to evaluate their dependability in aquaculture development in Gopalpur Upazila under Tangail district. Accordingly, criteria were identified; data were located, collected, compiled and incorporated in to the computer for analysis followed by the approach by Kapestky (1994). The sub models were weighted according to their role in aquaculture development. Finally, Multi Criteria Evaluation (MCE) was employed to ascertain and priorities the most suitable areas for aquaculture development in the region. The study has identified 4 km2 very suitable land parcel which is situated in the middle and eastern part of the area where all most all the criteria coincide well. Moreover, model has also identified 194 km2 moderately suitable lands which covered all most all the Upazila. However, a small tip of land parcel (1%) falls under marginally suitable category located in the extreme periphery of the eastern region which may have not matched some of the criteria well. The outcome of this analysis was verified with the fish production data and most availability of fishes in the area which fairly matched with result.
Key words: Aquaculture, resource mapping, GIS, potentiality, development.
