Its fishery, however, focuses on a much smaller group of species, and researchers and fisheries managers have raised concerns about fishing pressure, gear, and catches of immature fish.
What fish live in Lake Tanganyika?
The lake’s fish community has two strikingly different parts: a highly diverse community associated with the bottom and shoreline, and a less diverse group of open-water fish. “Littoral” means near-shore habitat; “pelagic” means open water. The term “demersal” refers to fish associated with the bottom.
Cichlids: the diversity standouts
Cichlids are central to Lake Tanganyika’s biodiversity story, and most are endemic—found naturally only in the lake basin. A 2020 taxonomic inventory reported at least 241 cichlid species, all but two endemic to the basin (2020 inventory). A separate fisheries frame-survey report published in 2025 gave a figure of at least 250 cichlid species, alongside 150 non-cichlid species (FAO frame-survey material). These are estimates from different sources, not a single settled count.
Open-water clupeids and Lates
FAO describes six endemic non-cichlid species in the pelagic community: two schooling clupeids, Limnothrissa miodon and Stolothrissa tanganicae, and four predatory Lates species: L. stappersii, L. angustifrons, L. mariae, and L. microlepis (FAO Lake Tanganyika fisheries overview). In the commercial-fishery descriptions, the two clupeids and Lates stappersii feature especially prominently.

Which fish are caught, and how are they fished?
The fishery does not target the lake’s many species equally. FAO describes a commercial fishery focused especially on pelagic clupeids and Lates stappersii, while fishing in near-shore areas uses varied gear and targets fish available in local habitats.
Night fishing for clupeids
Clupeids are attracted to light, so many fisheries target them at night. FAO lists purse seines, lift-nets, beach seines, and scoop-nets among methods that use this behavior. An older FAO fisheries account observed that activity could largely stop around the full moon; that is a historical observation, not a rule established for every fishery today (FAO fisheries background).

Different gears in different settings
FAO’s historical description distinguishes semi-industrial purse seining from artisanal lift-netting and traditional or subsistence fishing using gear such as gillnets, hooks and line, scoop-nets, longlines, and traps. A study of the northwestern littoral fishery near Uvira recorded beach seines, frame gillnets, and mosquito nets; the gear used varied with shoreline substrate (Uvira littoral study).
What does the Uvira study show about catches?
The Uvira findings are specific to one place and period, not a lake-wide estimate. During fieldwork from March to July 2010, researchers examined 3,555 cichlids representing 47 species and 30 genera. In that examined catch, 63% were immature or small-sized. The study also reported that beach seines caught more species on sandy substrate, while frame gillnets caught more individual fish (Uvira littoral study).

- Seachem Cichlid Lake Salt- Natural Environment of African Cichlids Treatment for Freshwater Aquariums
- Cichlid Lake Salt is a chemically sound blend of salts designed to replicate the natural environment of Rift Lake African Cichlids
- The blend of salts contains all physiologically essential elements such as magnesium, calcium, sodium, potassium, and includes traces components such as iron, aluminum, and iodide
That result helps explain why gear choice matters: different methods can take different fish and produce different catches in different habitats. It does not establish the proportion of immature fish caught elsewhere on the lake or in other years.
Why is fishing challenging?
Fishing on the lake involves practical demands as well as ecological concerns. Night work, dependence on weather and fishing grounds, and unequal access to boats, gear, and infrastructure shape how fishing is carried out. The methods vary by region and scale, so a gear’s effects should be understood in its local setting rather than assumed to be identical around the lake.

- Carefully packed and shipped to promote safe arrival
Management concerns include high fishing pressure, prohibited or illegal gear, fishing in regulated areas, and the capture of immature fish. At a 2020 project launch, FAO’s Resident Representative in Burundi, Isias Angwe Obama, said that open access, a very high number of fishers, prohibited gear, and illegal practices were factors responsible for declining productivity. That was a statement made at the project launch, not a finding from a new lake-wide stock assessment (FAO project-launch announcement, 2020).

A 2000 FAO/AfDB report estimated an annual harvest of 165,000–200,000 metric tonnes in the “recent years” covered by that report, and annual earnings of US$80–100 million. It estimated that around one million people relied on the fisheries when harvesters, post-harvest workers, service providers, and dependent households were included. The report also estimated that the lake’s catchment served 10 million inhabitants. These are historical estimates published in 2000, not current totals or values (FAO/AfDB field report, 2000).

What is known about current fish stocks?
A 2026 FAO update described the second phase of a comprehensive stock survey, following an initial phase in September 2025. Researchers were measuring the biomass, size, and distribution of sardines, sprats, and perch, as well as water conditions including temperature, turbidity, dissolved oxygen, pH, nutrients, and pollutants. The update said data analysis and validation would take at least another two months, with results expected later in 2026. It did not provide final validated results, so it cannot establish whether stocks are stable, declining, or recovering (FAO update on the second assessment phase, 2026).
Prisca Mziray, Center Director of the Tanzania Fisheries Research Institute in Kigoma, said the upgraded equipment, regional collaboration, and technical support would provide “unprecedented clarity” on fish-stock status. Her statement expressed confidence in the assessment’s expected findings; it was not itself a finding about stock condition (FAO update, 2026).
