Cichlid Genome Resources

The more than 25,000 species of bony fishes represent more than half of all living vertebrates.\n";echo "Among these, the perch-like fishes (Order Perciformes) includes more than 9,300 species (Nelson, 1994). \n";echo "We are working with laboratories around the world to develop genomic resources for one of the most \n"; echo "diverse groups of Perciformes, the family Cichlidae (>1500 species). Cichlids (pronounced 'siklids') \n"; echo " are found in tropical regions of the Americas, Africa, Madagascar and Sri Lanka, but achieve their \n";echo "greatest diversity in the Great Lakes of East Africa.

\n";echo "The three major lakes in East Africa (Malawi, Tanganyika and Victoria) each harbor a separate radiation \n";echo "of several hundred species. The radiations in Lakes Malawi and Victoria have occurred in roughly the last \n";echo "million years, making this the most rapid rate of speciation known in vertebrates, and a fascinating system \n";echo "for studying the mechanisms of evolution and speciation. These fishes are also excellent model \n";echo "organisms for studying the genetic and developmental basis for differences in morphology and behavior.

Tilapia (Oreochromis spp.) are cichlid fishes which shared a common ancestor with \n";echo "East African lake flocks about 10 million years ago. They are one of the most important \n";echo "species in aquaculture today, with world-wide production exceeding 1 billion \n";echo "pounds per year. Increasingly popular in western cuisine, tilapia are a particularly important \n";echo "source of protein in less developed countries.
