**Kigoma, Tanzania** – Lake Tanganyika, the world’s longest freshwater lake, is facing a severe fishing crisis. Fish production has plummeted nearly 20 percent between 2020 and 2024, impacting the livelihoods of millions in Tanzania, the Democratic Republic of Congo, Burundi, and Zambia. This decline, coupled with increasing population pressure and the effects of climate change, threatens the lake’s future as a vital food source.

For decades, Lake Tanganyika has been a cornerstone of the regional economy, providing 40 percent of Tanzania’s fish catch alone. However, fishermen report drastically reduced hauls. One fisherman, Dunia Omari Kiswabe, stated his daily catch has dropped from 50 buckets of dagaa (a type of sardine) to just 10.

The Tanzanian government implemented a three-month fishing ban in 2024 to allow fish stocks to recover. While initial reports suggested a rebound, the lack of comprehensive data since a 1996 assessment makes it difficult to determine the ban’s long-term effectiveness. Experts warn that overfishing is only one factor contributing to the crisis. Warmer water temperatures and slower wind speeds, linked to climate change, are disrupting the lake’s natural nutrient cycle, further impacting fish populations. A 2016 study even suggests fish decline began before the surge in commercial fishing in the mid-20th century.

Faced with dwindling fish stocks, communities are exploring alternative income sources. The government promoted aquaculture (fish farming) but faces challenges including limited loan access and insufficient training for aspiring fish farmers. Community-based initiatives, such as a conservation bank in Rukoma, are empowering residents to diversify their income through entrepreneurship.

While some hope remains in aquaculture and community-led conservation efforts, the long-term viability of these solutions is uncertain. Experts emphasize the need for comprehensive data collection, improved fisheries management, and adaptation strategies to address the multifaceted challenges facing Lake Tanganyika. The future of this vital ecosystem depends on the ability of communities and governments to address both immediate fishing pressures and the broader impacts of climate change and population growth.
