Kampango

What it is

This large predatory catfish is native to the Lake Malawi basin in Africa. Adults have a dark, almost black appearance, while juveniles are grey with dark spots. Females generally grow larger than males. The species can reach lengths of up to 1.5 metres, though a typical adult measures around 42 centimetres. It inhabits freshwater environments, preferring rocky zones in shallow waters under 50 metres deep. It also lives over sandy or muddy lake floors, staying within oxygenated depths. During daylight hours, the fish hides inside caves to rest.

Where it lives

This fish is endemic to a specific region in Africa, found exclusively in Lake Malawi, Lake Malombe and the upper Shire River. It occupies various depths within these freshwater bodies. While it shows a strong preference for rocky shallows under 50 metres, it will also venture into deeper waters as long as oxygen levels remain sufficient. The bottom composition in its habitat varies, with the species adapting to both sandy and muddy substrates. Fishing activities for this catfish frequently occur in deeper zones near locations like Cape Maclear, Salima, Mbenje Island and Nkhata Bay.

How it lives

Kampangos are solitary hunters that emerge from their daytime cave shelters at dusk and dawn to feed. Their primary diet consists of cichlids. The species engages in complex ecological relationships with other fish. For instance, the cichlid Pseudotropheus crabro acts as a cleaner, removing parasites from the catfish, though it also steals eggs. Conversely, some cichlids deliberately release their offspring near kampango nests to benefit from the catfish's fierce parental defence. The catfish also falls victim to brood parasitism by another catfish, Bathyclarias nyasensis, which tricks the kampango into raising its young.

Breeding and life cycle

Reproduction begins when the male excavates a shallow nest in the sand, usually close to rocks. The female then deposits thousands of eggs. Both parents fiercely guard the clutch. After hatching, the fry feed on unfertilised eggs provided by the mother and invertebrates carried in the father's mouth. The young remain under parental protection until they reach about 12 centimetres in length. Before reaching this size, many are consumed by egg-stealing cichlids.

Fish and people

People highly value the kampango as a food fish. Local fishers catch it using nets and lines, primarily targeting deeper waters. Local cuisine often features the fresh catch sliced, fried, grilled, or prepared with tomatoes and onions, accompanied by nsima. Despite its historical abundance, the species is now heavily overfished. Catch rates in southern Lake Malawi dropped by over ninety percent between 2006 and 2016, leading to its current critically endangered status.

Status and threats

The International Union for Conservation of Nature lists the kampango as critically endangered. Historically considered widespread and common across its native range, the population has suffered a drastic collapse. The primary threat driving this decline is severe overfishing. Fisheries data from southern Lake Malawi indicates a population drop of more than ninety percent over a ten-year period ending in 2016. Without intervention to reduce fishing pressure, the species faces a high risk of extinction in its natural habitat.

Relatives and look-alikes

The kampango shares its habitat with numerous cichlid species, which form the bulk of its diet. It interacts closely with the cichlids Mylochromis melanonotus and Pseudotropheus crabro, which prey on its eggs. It is also ecologically linked to the catfish Bathyclarias nyasensis, a brood parasite that exploits its nesting behaviour.
