What is unique breeding&spawning in Synodontis?
Breeding & Spawning Synodontis Multipunctatus Catfish S.multipunctatushas an unusual spawning behavior; it utilizes mouth-brooding Cichlids as foster parents for their fry.
What is Synodontis multipunctatus?
Synodontis multipunctatus is an African catfish native to Lake Tanganyika where it inhabits muddy bottoms down to at least 100 m. The largest known wild specimen was 27.5 cm in length. The temperature in the aquarium should be kept between 21 – 25°C and the hardiness in the dH 15-35 range.
What is the scientific name of Synodontis multipunctatus?
Scientific name: Synodontis Multipunctatus. Average Adult Fish Size: 10.8 inches / 27.5 cm in the wild, but 6 inches / 15 cm is more likely in an aquarium. Place of Origin: Lake Tanganyika, Africa. Typical Tank setup: Rocky African biotope with roots/driftwood/bogwood and caves.
What is the only fish that has brood parasitism?
It is one of the only fish known to exhibit a method of spawning known as brood parasitism, the others also being Tanganyikan Synodontis species! The catfish times its spawning to coincide with that of a ‘host’ mouthbrooding cichlid and lays its eggs among those of the host fish.
What are brood parasites?
Brood parasites are organisms that rely on others to raise their young. The strategy appears among birds, insects and some fish. The brood parasite manipulates a host, either of the same or of another species, to raise its young as if it were its own, using brood mimicry, for example by having eggs that resemble the host’s (egg mimicry).
Is parasitism maladaptive to host species?
However, at high enough parasitism frequencies, this becomes maladaptive as the new nest will most likely also be parasitized. Some host species modify their nests to exclude the parasitic egg, either by weaving over the egg or in some cases rebuilding a new nest over the existing one.
What is a criticism of the parasitism hypothesis?
A criticism of the hypothesis is that it provides no mechanism by which nests are chosen, or which cues might be used to recognize such a site. Parental-care parasitism emphasizes the relationship between the host and the parasite in brood parasitism.
What is a fish parasite called?
A fish parasite, the isopod Cymothoa exigua, replacing the tongue of a Lithognathus. In evolutionary biology, parasitism is a relationship between species, where one organism, the parasite, lives on or in another organism, the host, causing it some harm, and is adapted structurally to this way of life.
What are some of the most infamous brood parasites?
Perhaps the most infamous brood parasite is the common cuckoo. Indeed, the common cuckoo is so notorious for forcing other birds to raise its young that the term ” cuckold ” was coined to refer to husbands of unfaithful wives.
Is brood parasitism polyphyletic in cuckoos?
^ Aragon; Moller; Soler; Soler (1999). “Molecular phylogeny of cuckoos supports a polyphyletic origin of brood parasitism”. Journal of Evolutionary Biology. 12 (3): 495–506. doi: 10.1046/j.1420-9101.1999.00052.x.
What is brood parasitism?
Brood parasitism is a breeding strategy in which the brood parasite female evades all parental care by laying its eggs in host nests of the same (conspecific brood parasitism, CBP) or different species (interspecific brood parasitism, IBP) relying on unrelated foster parents to care for their parasitic offspring.
Can brood parasites lay eggs in other nests?
Brood parasites can deposit eggs in the nests or broods of another individual of the same (conspecific brood parasitism) or of a different (interspecific brood parasitism) species. Hosts often raise young of the brood parasite, typically at the expense of their own young.
How are fish parasites dispersed?
The dissemination of fish parasites throughout freshwater localities is due primarily to the movements of fish or bird hosts, whether natural or anthropochore (Kennedy, 1988) are dispersed naturally more readily than autogenic species and so can confer more similarity between communities.
What is the relationship between brood parasites and their hosts?
The relationships between brood parasites and their hosts have been studied in most detail in birds, where the subject of brood parasitism have provoked an explosion of compelling discoveries revealing the refinement and complexity of the strategies evolved by brood parasites and their hosts.
Are most parasite populations in freshwater fish unregulated and unstable?
Until evidence from more long-term studies is available, the null hypothesis that most parasite populations in freshwater fish are unregulated and unstable must be accepted. This supports the view of Price (
How many freshwater fish species are infected by parasites in Thailand?
The diversity of fish parasites from freshwater fishes collected from the Nong Han wetland (Udon Thani Province, Thailand) was studied by visually examining 22 freshwater fish species (253 samples) from 19 genera for external and internal parasites. A majority of fishes in the Nong Han wetland were infected by parasites (75.89%).
Why do fish have parasites?
Like other living organisms, fish harbour parasites either external or internal which cause a host of pathological debilities in them. The parasites live in close obligate association and derive benefits such as nutrition at the host\\’s expense, usually without killing the host.

What are the host manipulations induced by brood parasites?
This hypothesis revolves around host manipulations induced by behaviors of the brood parasite. Upon the detection and rejection of a brood parasite’s egg, the host’s nest is destroyed and nestlings injured or killed.
What is an example of a brood parasite?
The common cuckoo is one example of a brood parasite. Such animals trick other animals into raising their young. They sneak their eggs into other parents’ nests. Brood parasites are “basically looking for foster parents,” says Mark Hauber, a biologist.
How do fish parasites affect the body?
The parasites have not shown any traces of causing other damage to the host’s body except replacing their organs and in some cases cause fish to lose weight. When the fish dies, the parasites detach from the tongue leaving a cavity in the mouth and then stick to the host’s head. The reproduction process is more interesting than this.
What are some examples of intraspecific brood parasitism?
Intraspecific brood parasitism is seen in a number of duck species, where females often lay their eggs in the nests of others. A Eurasian reed warbler raising a common cuckoo. A black-collared starling feeding an Asian koel.
