Bruton. 5166), Nile basin (including lake Albert, Edward and Tana), Jebel ... where larvae hatch and remain until the vitellus is reabsorved. Reproduction occurs only when temperature exceeds 20 °C. Reported from Alabama and Arizona. In many instances the breeding cycle is synchronized with the rainy season. 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. McCann. Burgess, N. Pronek, and J.G. Aquatic Invasions 7: in press. A knob-like protuberance absent on dorsal surface of snout. At second week, D. magna size was 0.6–1.0 mm with density of 1467 D. magna/L. Widely distributed in Nile and Niger river basins and in lakes Tanganyika, Albert, Edward, and George, as well as in many smaller drainages and lakes in western and eastern Africa; also in Middle East in Yarkon River, Israel (Trewavas 1983). They are fast-growing and give good fillets! 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 female incubates the eggs for 5-7 days when they hatch and the early juveniles remain in the mouth until after yolk sac absorption. The eggs are large and ovoid (pear shaped) and at hatching the fish are around 4mm in length (Trewavas, 1983). The Nile tilapia (Oreochromis niloticus) is a species of tilapia, a cichlid fish native to the northern half of Africa and the Levante area, including Jordan, Palestine, Israel, and Lebanon. 2006. First gill arch with 27 to 33 gillrakers. The males tend o grow larger due to a high efficiency of converting food to energy. However, when introduced outside its native range, it often becomes invasive, threatening more localized species. What is a typical, suitable proximate composition of a diet for Nile tilapia? To support the growing tilapia industry, there is a need to provide year-round, high-quality seed that can be widely distributed at reasonable costs to tilapia farmers. The length at 50% maturity was estimated as 31.0 cm TL for male Nile tilapia and 26.0 cm TL for females. Partyka. Harvest weight and survival. Environmental Conservation 6(2):149-151.

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 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).

The Nonindigenous Occurrences section of the NAS species profiles has a new structure. Tilapia populations in large lakes mature at a later age and larger size than the same species raised in small farm ponds. Owing to its hardy nature, and its wide range of trophic and ecological adaptations, it has been widely introduced for aquaculture, augmentation of capture fisheries and sport fishing (Trewavas, 1983; Welcomme, 1988), and is now found in every country in the tropics. 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.
