Ripples of Change on Lake Tanganyika: Inside the Drive to Safeguard Zambia’s Kapenta Economy

Along the breeze-swept shores of Mpulungu District, where the emerald waters of Lake Tanganyika meet the bustle of local commerce, a crucial conversation about the future of Zambian fisheries has taken center stage. As one of the nation's most critical inland water bodies, Lake Tanganyika supports thousands of livelihoods, providing an essential source of affordable protein and income for communities across northern Zambia. However, mounting environmental pressures, climate variability, and intensive fishing practices have raised alarm bells among conservationists, government officials, and industry players alike. At the heart of the dialogue is the preservation of the small pelagic fish locally known as kapenta. For generations, the harvesting and processing of kapenta have formed the economic backbone of Mpulungu, sustaining families and driving local trade. In recent years, however, fishers have reported declining catches and smaller average fish sizes—symptoms of a resource under strain. Experts attribute these trends to a combination of overexploitation, the use of prohibited fine-mesh nets that trap juvenile fish, and shifting climatic conditions affecting the lake's delicate aquatic ecosystem. Recognizing the urgency of the crisis, public and private sector stakeholders have rallied behind sustainable management frameworks. Collaborating through initiatives backed by regional bodies and international development partners, the Ministry of Fisheries and Livestock has pushed for enhanced compliance, robust data collection, and better post-harvest handling. Because a significant portion of harvested fish is lost due to inadequate processing infrastructure—disproportionately affecting women traders—investments in modern solar-powered cold storage and improved drying methods are vital to transforming the value chain. Local cooperatives and women-led enterprises are increasingly at the forefront of these reforms, adopting alternative livelihood strategies and sus
