Mouthbrooding, also known as oral incubation and buccal incubation, is the care given by some groups of animals to their offspring by holding them in the mouth of the parent for extended periods of time. Although mouthbrooding is performed by a variety of different animals, most notably Darwin’s frog, fishes are by far the most diverse mouthbrooders. Mouthbrooding has evolved independently in several different families of fish.[1]

Mouthbrooding behaviour

Paternal mouthbrooders are species where the male looks after the eggs. Paternal mouthbrooders include the arowana, the mouthbrooding betta Betta pugnax, and sea catfish such as Ariopsis felis. Among cichlids, paternal mouthbrooding is relatively rare, but is found among some of the tilapiines, most notably the black-chin tilapia Sarotherodon melanotheron.

In the case of the maternal mouthbrooders, the female takes the eggs. Maternal mouthbrooders are found among both African and South American cichlids. African examples are the haplochromines, such as the mbuna, Astatotilapia burtoni, and the dwarf mouthbrooders Pseudocrenilabrus multicolor, and some of the tilapiines, such as Oreochromis mossambicus and Oreochromis niloticus. The South American maternal mouthbrooders are all members of the Geophaginae subfamily (commonly known as “eartheaters” on account of their substrate-sifting feeding mode) such as Gymnogeophagus balzanii and Geophagus steindachneri.

Biparental mouthbrooding occurs where both parents take some of the eggs. This is relatively rare, but is found among the cichlid genus Xenotilapia, and a single catfish, the spatula-barbled catfish (Phyllonemus typus).

Typically, after courtship, the male fertilises the eggs and then collects them in his mouth, holding onto them until they hatch. During this time he cannot feed. Among the maternal mouthbrooding cichlids, it is quite common (e.g., among the mbuna) for the male to fertilise the eggs only once they are in the female’s mouth. Some cichlids are able to feed while mouthbrooding the eggs, but invariably they feed less often than they would otherwise do, and after mouthbrooding one batch of eggs, all mouthbrooding fish will be underweight and requiring a period of time to feed and make up for the depletion of their energy reserves.[2]

In all cases, the eggs are protected until they hatch and the fry become free swimming. Only in some cases does the parent extend protection to mobile juveniles. Among the cichlids and arowanas, extension of brood care to the fry is common, and they have behavioural cues to tell fry swimming and feeding away from the parent that danger is approaching and that they should return to their parent’s mouth. By caring for their offspring in this way, mouthbrooding fish are able to produce smaller numbers of offspring with a higher chance of survival than species that offer no broodcare.

Aquaculture

Some commercially important fish are mouthbrooders, most notably among the tilapiines and arowanas. Fry harvesting, getting the brooding fish to open its mouth and release the fry, is important if the fry are to be reared artificially. In the case of endangered species, such as Asian arowana, harvesting may be supervised by an official who will certify that the fish farm is a genuine producer of captive-bred fish.[3][4][5]

Brood parasites

Some fish have evolved to exploit the mouthbrooding behaviour of other species. Synodontis multipunctatus, also known as the cuckoo catfish, combines mouthbrooding with the behavior of a brood parasite: it will eat the host mouthbrooder’s eggs, while spawning and simultaneously laying and fertilizing its own eggs. The mouthbrooder (typically a cichlid) will incubate the cuckoo catfish young, the catfish eggs hatch earlier than the cichlid’s eggs, and eat the as-yet unhatched cichlid eggs before being set free.
