The Nile tilapia typically feeds during daytime, which suggests that, similar to trout and salmon, it exhibits a behavioral response to light as a main factor contributing to feeding activity. Due to its fast reproductive rate, however, overpopulation often results within groups of Nile tilapia.
For example, blue tilapia (Oreochromis aureus) (itself commonly confused with another species often used in aquaculture, the Nile tilapia, O. niloticus), Mozambique tilapia (O. mossambicus), blackchin tilapia (Sarotherodon melanotheron), spotted tilapia (Pelmatolapia mariae), and redbelly tilapia (Coptodon zillii) have all become established in ...
Red nile tilapia under experimentation in CLSU, Philippines. Farmed tilapia production in 2002 worldwide was about 1.5 million tonnes (1.7 million short tons) annually, with an estimated value of US$1.8 billion, [40] about equal to those of salmon and trout. Unlike carnivorous fish, tilapia can feed on algae or any plant-based
Adult members of the tilapia Oreochromis mossambicus prey upon a variety of organisms within the Salton Sea. The polychaete worm Neanthes succinea is an important part of tilapia diet. [28] In addition to polychaete worms, adult tilapia regularly feed upon phytoplankton, copepods, smaller fishes and barnacles. [29]
Many cultured fishes (tilapia, carp, catfish, many others) can be raised on a strictly herbivorous diet. Top-level carnivores (most salmonidae species in particular) on the other hand, depend on fish feed, of which a large portion is usually derived from wild-caught fish (anchovies, menhaden, etc.). Vegetable-derived proteins have successfully ...
The cichlid Haplochromis thereuterion is endemic to Lake Victoria.. In 1927-1928 Michael Graham conducted the first ever systematic Fisheries Survey of Lake Victoria.The dominant species in the 1927–8 survey catches were two, now critically endangered tilapia species, the 'Ngege' or Singida tilapia (Oreochromis esculentus) and Victoria tilapia (O. variabilis).

WorldFish has worked to breed genetically enhanced fast-growing tilapia (GIFT) varieties to raise the productivity and incomes of low-income smallholder farmers. It also works to improve the production of key inputs for aquaculture, specifically fish feed and fingerlings, and links small-scale aquatic food producers with input and output ...
