In an initiative in Zonheboto district, the fish population in Tizu River had reportedly declined due to the use of explosives and other destructive means of fishing. Villagers around the river decided to come together and ban the use of explosives in the river. Violation fines are shared with 50 per cent going to the informant and the rest to the gaon bura (GB) Union. In 5-6 years fish population has increased substantially. According to the villagers the effort was initiated out of a concern for the fish population and with no other objective.
