- Boulenger, George Albert. 1906. "Fourth Contribution to the Ichthyology of Lake Tanganyika - Report on the collection of fishes made by Dr. W. A. Cunnington during the third Tanganyika Expedition, 1904-1905". Transactions of the Zoological Society of London. [17, Part 6](1):537-619. DOI: 10.1111/j.1096-3642.1905.tb000 (crc00004)
Conservation: Cunningtonia longiventralis is evaluated by the international union for the conservation of nature in the iucn red list of threatened species as (LC) least concern (2006). Cunningtonia longiventralis is not a very common species of the shallow intermediate habitat and seines cannot be employed in these kind of areas. Since C. longiventralis is a pure vegetarian it is unlikely that sufficient numbers can be caught with hook and line to have an impact on the population density.
