Geospatial assessment of changes in fishing grounds of the Nigerian portion of Lake Chad was carried out. The aim was to investigate the fishing grounds, types of fishing gears, and the species of fish caught at the site. Remotely sensed data and GIS techniques were used to assess the changes in fishing grounds of the Nigerian portion of Lake Chad. Satellite imageries of the study area were used for this research. The satellite data were processed and analyzed using GIS software packages, ground truth exercise was also conducted in order to ascertain the reality of some generated information from the remotely sensed data. Likewise, information on types of gear used in the fishing grounds and the types of fish caught in the fishing grounds were obtained from fishermen through Focus Group Discussion. The result revealed that open water and swampy area were identified as the fishing grounds in the study area. While the trends show that open water has been changing over time, wherein 1999 it covers about 17.20% of the Nigerian portion of the Lake Chad. And in 2013 it covers about 6% of the study area. While the swampy area as a fishing ground was stable, and it covers most parts of the study area than other classes. The result also revealed that there were some specific fishing gears (such as Malian trap, Hooks, and nets) and types of fishes (such as Tilapia, Cat fish, and long fish) that are caught in those fishing grounds.
