The land of Punjab during the British rule was used by the ruling class for their environmental as well as commercial benefits. The water of the five rivers of Punjab was used for irrigation and was directed towards the areas where water was scarce, through canals and small tributaries. In addition, they were also used for angling. During the British rule, the officials preserved nature as well as earned profits by exploiting the environment of Punjab. While serving commercial deeds of the British, waters of Punjab also served as source of recreation for the British, which established complex pattern of social interaction. Such aspirations of the British led to the development of the fisheries in the region. Punjab was introduced to new fish by the fisheries department. Nurseries, hatcheries, and sanctuaries were developed to stock streams for increased fish populations. The fisheries of the state's riverine and canal resources were exploited through a license and lease system.
