Large helpers (nannies) in a cichlid fish allow the dominant male and female to reduce their personal contribution to their offspring and territory, according to new research published today in Functional Ecology. By removing the large helper for 30 days — which corresponds to one breeding cycle in this species — a team from the University of Bristol and the University of Bern (Switzerland) studied the investment strategies of the dominant pair and the survival of their brood,...

Author Of Darwin's Dreampond Has New Fish Species From Lake Victoria Named In Honor Of Him
2013-01-02 10:25:23

Pensoft Publishers Two new species of cichlid fish from Lake Victoria are described by biologists from Naturalis Biodiversity Center (Research Department Marine Zoology) and the Institute of Biology Leiden (Section Integrative Zoology), the Netherlands. One of these species is named in honor of Tijs Goldschmidt, author of Darwin's Dreampond. This book, published in nine languages, describes the dramatic extinction of hundreds of cichlid species in Lake Victoria in the 1980s due to the...

Swimming With Hormones Ancient Urges That Drive The Social Decisions Of Fish Unraveled
2012-10-09 17:54:11

Researchers have discovered that a form of oxytocin–the hormone responsible for making humans fall in love–has a similar effect on fish, suggesting it is a key regulator of social behavior that has evolved and endured since ancient times. The findings, published in the latest edition of the journal Animal Behaviour, help answer an important evolutionary question: why do some species develop complex social behaviors while others spend much of their lives alone? "We know how...

How Does The Swim Bladder Affect Hearing In Cichlid Fish?
2012-08-08 11:35:57

"Sound vibrations are transmitted to the inner ear via anterior extensions of the swim bladder or via bony ossicles", the biologist Tanja Schulz-Mirbach explains how swim bladders may serve for hearing. The hearing sensitivity improves considerably in this way. The anterior part of the swim bladder functions in specialized fish species similar to an ear drum. Up to now the effects of the different swim bladder morphologies have not been investigated in detail in cichlid fishes. The...

Subordinate male cichlid fish who help with the childcare for the dominant breeding pair are occasionally actually the fathers of some of the offspring they help to rear, according to new research from the University of Bristol published today in PLoS ONE. This sneaky paternity increases the subordinate fish´s investment in the offspring in their care. The highly social cichlid fish Neolamprologus pulcher, endemic to Lake Tanganyika in Africa, live in social groups consisting of a...

For the first time ever, scientists have found a difference in the way males and females of the same species of vertebrate see things "“ and that sexes likely use that difference to select their mates. Queen's PhD candidate Shai Sabbah, a Vanier Scholar, led a team of researchers who found that male and female cichlid fishes not only see things differently, but detect light in different ways as well. "It is difficult to say what color attracts the female the most, but we know that if we...

Caring for children can be a tough job, particularly if you are a female cichlid fish. Native to the crater lakes of Nicaragua, cichlid fish look after their young by defending them against would-be predators. While male and female cichlid fish generally share parental responsibilities, research shows that this is not always the case. Conducted by an international team of researchers that included two biologists from Monash University, and published in the journal Behavioral Ecology and...

Fish become feisty but fearful when facing themselves in a mirror, according to two Stanford biologists. "It seems like something they don't understand," said Julie Desjardins, a post-doctoral researcher in biology and lead author of a paper to be published in Biology Letters describing the study. The paper is available online now. "I think this stimulus is just so far outside their realm of experience that it results in this somewhat emotional response." Desjardins and coauthor Russell...

Putting function before form, members of the Perissodinus genus of fish have developed a hugely lopsided jaw that provides a distinct feeding advantage. Research published in the open access journal BMC Biology describes how these scale-eating fish, called cichlids, develop mouths directed either to the left or the right "“ enabling them to feed on the opposite side of their prey. A research team from Syracuse University, led by Thomas Stewart and R. Craig Albertson, studied the facial...

The poster child for sustainable fish farming -- the tilapia -- is actually a problematic invasive species for the native fish of the islands of Fiji, according to a new study by the Wildlife Conservation Society and other groups. Scientists suspect that tilapia introduced to the waterways of the Fiji Islands may be gobbling up the larvae and juvenile fish of several native species of goby, fish that live in both fresh and salt water and begin their lives in island streams. The recently...

The Spotted tilapia (Tilapia mariae) is a fresh and brackish water fish of the cichlid family. It is native to Africa from the Côte d'Ivoire to Ghana, and Benin to Cameroon. Like several other tilapiine cichilds, the spotted tilapia is notable for its adaptability and prolific breeding. This fish has established large feral populations outside of their native ranges, such as in Florida, where they are a troublesome invasive species.
