It is also commercially known as mango fish, nilotica, or boulti. Bruton. 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. This information is preliminary or provisional and is subject to revision.

Dispersal of living organisms into aquatic ecosystems. Catalogue of freshwater and marine fishes of Alabama. Introduction Nile tilapia, Oreochromis niloticus (L.) is one of the most known members of the McCann. They mostly feed on phytoplankton and algae, and in some populations other macrophytes also are important. The nest, like in many tilapiine fishes, is a circular depression in sandy areas of up to 1m in diameter and 0.5 m deep. Beamish. Sims Printing Company, Inc., Phoenix, AZ. - Georgia Department of Natural Resources, Atlanta, GA. The zoogeography of North American freshwater fishes. It lives for up to 9 years. The average nest diameter is twice the length of the male making it. 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. In many instances the breeding cycle is synchronized with the rainy season. † Populations may not be currently present. 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). Maryland Sea Grant Publication, College Park, MD. Checklist of the inland fishes of El Salvador. They are fast-growing and give good fillets! To answer your question with a number, it takes 240 days, or 34 weeks for food grade tilapia to reach a 16 to 20 ounce harvest size. Courtenay, W.R., Jr., D.A. Competitive interactions between invasive Nile tilapia and native fish: the potential for altered trophic exchange and modification of food webs. Males are highly territorial and defend their nests. 1992. Caudal fin has 7-12 distinct vertical stripes. The Mozambique tilapia reaches sexual maturity at a smaller size and younger age than the Nile and Blue tilapias. Hocutt, and E.O. The eggs are large and ovoid (pear shaped) and at hatching the fish are around 4mm in length (Trewavas, 1983). 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). 1992. 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. Peterson, M.S., W.T.

Lower pharyngeal with firm teeth in approximately triangular dentigerous area. Chlorophyceae is the dominant group at large fish size (>75 g/fish). Waggy, J. Finley, C.M. The species is a nest building, batch spawning mouth brooder that can spawn every 30 days. Body compressed; caudal peduncle depth equal to length. Vertebrae 30-32. 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. Fishes of Arizona. Nile Tilapia have also been introduced into Thailand (Tongnunui and Beamish 2009) and El Salvador (McMahan et al. Dispersal of exotic species from aquaculture sources, with emphasis on freshwater fishes. Reproduction occurs only when temperature exceeds 20 °C. In the present study, male Nile tilapia were reared individually in aquaria, in order to measure individual BWG, FI and FCR from the juvenile stage (36 g) up to commercial size (250−300 g), and to evaluate the relevance of FCR estimated over short … 1986. Zambrano, L., E. Martínez-Meyer, N. Menezes, and A.T. Peterson. Tongnunui, S., and F.W.H. Depending on size, females can carry up to 200 eggs. As Nile tilapia grows to adult size; it becomes entirely herbivorous, feeding on phytoplankton [43-45]. Khallaf, E.A., and A.A. Alne-na-ei. We highly recommend reviewing metadata files prior to interpreting these data. Tilapia in Texas waters. ReproductionSexual maturity is reached at 10-30 cm TL and is related to the maximum size attained in a given population and condition, which in turn is determined by food availability and temperature. Food grade tilapia are simply those tilapia that exhibit the fastest rates of growth. Established locally (Alachua County) in Florida. Grammer et al. Hensley. Valentine. 5166), Nile basin (including lake Albert, Edward and Tana), Jebel ... where larvae hatch and remain until the vitellus is reabsorved. (Market Set - Varies Contact For Pricing) Average weights 5 inch Tilapia can weigh = 40g, 6 inch = 58g varies #5 WHOLE TILAPIA: 8 inch & up. Batches of eggs are spawned into the nest, fertilized externally and then picked up by the female. Gainesville, Florida. 2006. Nile Tilapia are fast-growing and produce good fillets. Body shape generally laterally compressed to oval and deep, though variable depending on the environment (Figure 1). D XVI-XVIII, 12-14, A III, 9-11. Environmental Biology of Fishes 76:283-301. Peterson, and M.A. The Nile tilapia (O. niloticus) has been introduced to South Africa for aquaculture as it has the potential to grow large and rapidly. 2013. Reported from Alabama and Arizona. 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.
