Nile tilapia are cheap and so cage culture is not cost-effective ... a market size of 700g in 4 months. The female incubates the eggs for 5-7 days when they hatch and the early juveniles remain in the mouth until after yolk sac absorption. Production costs in ponds are much lower, however, as natural planktonic and benthic food contributes significantly to the fish’s diet.

Tilapia has become the third most important fish in aquaculture after carp and salmon; worldwide production exceeded 1.5 million metric tons (1.5 × 10 ^ 6 long tons) in 2002 and increases annually. The Nile Tilapia was even well known as a food fish in Ancient Egypt, as depicted in paintings and sculptures of the day. Impact of Introduction: Nile Tilapia exert competition pressures on native fish and are known to prey on amphibians and juveniles of other fish species (Zambrano et al. In many instances the breeding cycle is synchronized with the rainy season. Genital papillae of male short and conical or bluntly bifid at tip and not tessellated. Spinous and soft ray parts of dorsal fin continuous. It is the user's responsibility to use these data consistent with their intended purpose and within stated limitations. The net return was higher in rearing the fingerlings from size #22 to size #10 (P11,851.12 = US$ 215.47) than in rearing the fingerlings from size #22 South African National Scientific Programmes Report 144. Nile Tilapia exert competition pressures on native fish and are known to prey on amphibians and juveniles of other fish species (Zambrano et al. Texas Parks and Wildlife Department, Inland Fisheries Data Series 9, Austin, TX. Lower pharyngeal with firm teeth in approximately triangular dentigerous area. Habitat and relative abundance of fishes in small rivers in eastern Thailand. But only the most carefully selected strains perform well; many inbred and stunted populations do poorly. Reproductively viable hybrids have resulted from these various crosses and thus, for most tilapia populations in the U.S., the use of meristics and traditional systematics to assign species names to specimens is not useful (see: Costa-Pierce 2003). Tilapia popula-tions in large lakes mature at a later age and larger size than the same species raised in small farm ponds. Figure 2:aw materials for production of R fish feed. Results revealed that Nile tilapia could select Cyanobacteria and Euglenophyceae at all sizes. All three species are introduced (or evolved in one environment and then introduced by humans into another), with the nile tilapia accounting for half of the total value. Reported from Alabama and Arizona. A knob-like protuberance absent on dorsal surface of snout. RESULTS. - Georgia Department of Natural Resources, Atlanta, GA. This information is preliminary or provisional and is subject to revision. Both males and females generally eat almost same amount of foods, but the males are tend to grow faster. The males tend o grow larger due to a high efficiency of converting food to energy. Invasive potential of common carp (Cyprinus carpio) and Nile tilapia (Oreochromis niloticus) in American freshwater systems. Breeding Nile Tilapia males have a red tone on the head as well dorsal and caudal fins. 675-698 in C.H. Body colouration varies depending on environmental, physiological and dietary factors. Result Males are highly territorial and defend their nests. Beamish. Reproduction occurs only when temperature exceeds 20 °C. Aquatic Invasions 7: in press. Dispersal of exotic species from aquaculture sources, with emphasis on freshwater fishes. Hence, increasing the proportion of adults in the population will also have a controlling effect on algal blooms that can be toxic when caused mainly by Cyanobacteria. _____________________________________________. Chlorophyceae is the dominant group at large fish size (>75 g/fish). Fish were harvested after 103 days at an average size of 172 grams in the GMT treatment, and 156 grams in the mixed-sex treatment.

The Nile tilapia, Oreochromis niloticus, has a broad natural distribution spanning from the Nile River basin southwards through the Eastern and Western Rift Valley lakes in East Africa, and westwards through the basins of Lake Chad, Niger, Benue, Volta, Gambia and Senegal rivers 1. Reproduction in nonnative environments: establishment of Nile tilapia Oreochromis niloticus, in coastal Mississippi watersheds. This species was introduced for aquaculture purposes. Possibly established in a large reservoir bordering Florida and Georgia. Grammer et al. If you breed your own tilapia, you can add another couple of weeks for egg incubation. These two species can generally be distinguished by the following characteristics (Trewavas 1983): Table 1. 1992. The length at 50% maturity was estimated as 31.0 cm TL for male Nile tilapia and 26.0 cm TL for females. This is a very large fish, reaching up to 24 inches in length and exceeding 11 pounds; its large size makes it very popular with aquaponics and aquaculture enthusiasts. Lateral line interrupted with 30-34 cycloid scales. For queries involving invertebrates, contact Amy Benson. 2013).

Under optimal conditions and using only surface aeration, food grade blue tilapia can grow to one pound in as little as 240 days. 1985. Khallaf, E.A., and A.A. Alne-na-ei. The species is a nest building, batch spawning mouth brooder that can spawn every 30 days. Citation information: U.S. Geological Survey. Taylor, and J.A. British Museum of Natural History, London, UK. 1987. Established in Mississippi. Eating tilapia all the time may help The breeding cycle is latitude dependent and spawning becomes more seasonal at higher latitudes. The species has been well studied from a taxonomic perspective.

The eggs are large and ovoid (pear shaped) and at hatching the fish are around 4mm in length (Trewavas, 1983). McCann. The most diagnostic features are the regular and definitive stripes on the caudal fin, the red flush of the breeding male and the dark margin of the dorsal fin. 1986. Nile Tilapia is primarily herbivorous, with aquatic macrophytes, algae, and diatoms generally comprising >90% of its diet and the remainder including aquatic insects and crustaceans and fish eggs (Khallaf and Alne-na-ei 1987). The Nile Tilapia fish are omnivore, and they feed on both plankton and aquatic plants.
