Scientists at the Georgia Institute of Technology have found that by applying chemicals to manipulate genes in a developing embryo, they've been able to change the brain of one type of cichlid fish to resemble that of another. The researchers also discovered differences in the general patterning of the brain very early in development before functional neurons form in a process known as neurogenesis. This finding is at odds with a well-held theory known as "late equals large." The research...

Diversity of fish in East African lakes points to mechanism for evolution of sex chromosomes Biologists have genetically mapped the sex chromosomes of several species of cichlid fish from Lake Malawi, East Africa, and identified a mechanism by which new sex chromosomes may evolve. In research published in this week's issue of the journal Science, biologists Thomas Kocher, Reade Roberts and Jennifer Ser of the University of Maryland describe the genetic basis for two co-existing systems of...

Lateral line sensory system detects vibrations from unseen prey Most fish rely primarily on their vision to find prey to feed upon, but a University of Rhode Island biologist and her colleagues have demonstrated that a group of African cichlids feeds by using its lateral line sensory system to detect minute vibrations made by prey hidden in the sediments. The lateral line system is composed of a canal embedded in the scales along the side of the body of a fish, around its eyes and on its...

By DAVID POWELL HOUSEHOLDERS in Conwy who recycle aluminium cans and foil have helped environmental projects in Malawi. Alupro (the Aluminium Packaging Recycling Organisation) is making sure an orange tree is grown to maturity for every tonne of aluminium drinks cans and foil recycled in the UK. Conwy residents have recycled 128 tonnes of aluminium cans and foil in just 12 months. So they have 'given' 128 fruit trees to families in rural Malawi. They are looked after on the shores...

THREE more clinical staff at Coventry's University Hospital are heading to Africa to help improve medical conditions there after receiving a fundraising boost. The International Committee of The Rotary Club of Coventry raised pounds 2,000 last year for Health Link Malawi charity which sends clinicians from the hospital to Nkhotakota, Malawi. It was the committee's chosen charity from July 2007 to June 2008 and during the year it raised money with a cheese and wine evening, theatre trip,...

A University of Arizona researcher suspects that a monster drought is behind our ancestors' massive bug-out from Africa. Lake Malawi, the third-largest lake in Africa and ninth-largest in the world, dropped nearly 2,000 feet during a mega-drought roughly 100,000 years ago, according to the UA's Andrew S. Cohen, the lead scientist on a report in the latest edition of the Proceedings of the National Academy of Sciences. The research was funded by the National Science Foundation, the...

Sciaenochromis is a genus of cichlid fish endemic to Lake Malawi in east Africa. It includes at least 4 species. The species are popular in the aquarium hobby. The most notable is S. fryeri, known in the aquarium trade as the electric blue. All Sciaenochromis are piscivores (fish-eaters) and prey mainly upon the fry of mbuna and other Haplochromine cichlids.

Pseudotropheus is a genus of rock dwelling (Mbuna) cichlids found in Lake Malawi. Like some other large cichlid genera, such as Cichlasoma, a number of related fish have been recently re-assigned to different genera such as Tropheops and Maylandia. Mbuna literally means "rock dweller" and this description accurately depicts the lifestyle of these cichlids which mostly live in rocky areas. Most Pseudotrophine cichlids are algal grazers in the wild. Pseudotropheus reproduction Like most...

Individuals display peculiar behavior in the wild and in captivity, including a hunting method in which it lies motionless while resting on the lake or aquarium bottom. In captivity, the fish may live to exceed 10 years of age and attain a length of 8 inches or more. Juveniles display a brown and white spotted pattern. Adult...
