Under optimal conditions and using only surface aeration, food grade blue tilapia can grow to one pound in as little as 240 days. Last on the list is the blue tilapia, which features a blue-gray hue with touches of pinkish-white in their belly. Copyright © 1996 Published by Elsevier B.V. https://doi.org/10.1016/0144-8609(95)00013-5. If you wish to use mono-sex cultures you will have to buy or produce all male fry (males grows faster and bigger than females). It’s growth rate and ultimate size sits somewhere between the Nile and the Blue Tilapia. The blue tilapia (Oreochromis aureus) is an important cultured fish worldwide, and exhibits sexual size dimorphism in favor of males, and therefore, mono-sex breeding is of great value for aquaculture.However, the lack of accurate sex-linked markers for blue tilapia has hampered the mono-sex culture in aquaculture, as well as study of sex determination in this species. Flotation can be provided by metal or plastic drums, sealed PVC pipe, or styrofoam. This reduces the growth rate in each individual tilapia but increases the overall yield per acre. All male fry can be produced through hormone treatment or hybridization. Only 4% of tilapia production is with Mozambican tilapia, in parts of the USA where it was introduced years ago. The typical mono-sex tilapia stocking density varies between 4,000 to over 20,000 fishes per acre. They were cultivated by human beings 2500 years ago, and now they have With aeration and denser stocking you will see a little slower growth rate in each fish but a higher overall yield. Our Aquaponics Grade blue tilapia have a more staggered growth rate to help maintain nitrifying bacteria in aquaponics systems. size classes of blue tilapia, Oreochromis aureus (Stein-dachner), designed to measure rates of ingestion and growth on diets of three aquatic macrophytes at two temperatures. We determined growth parameters, mortality and reproductive aspects for 2 413 specimens of blue tilapia … temperature of cultivation influences the growth description of Red, GIFT and Supreme tilapia strains. optimum condition for farming blue tilapia, Oreochromis aureus, both with respect to growth rate and metabolic parameters is at salinities lower than 12 ppt. Greater Uniformity of Size at Harvest. Due to this reason it is very important to avoid to dense stocking. These species are prevalent in the Florida area in the United States. You should therefore always research this carefully before deciding to get hormone treated tilapia. Blue Tilapia. Growth is actually an increase in any dimension of any organism in relation to time. If your tilapia are between five and six inches long, the average growth rate is 3% per day. Tilapia growth rates are influenced by a variety of factors; water temperature, sex, supplemental feeding, and stocking density noticeably affect their growth rate. As far back as 1983, R.S.V. For blue tilapia in Aguamilpa, estimates of b for males, females and total catch growth rate indicate a negative allometric (b <3), which is similar to reservoirs in Cuba (Fonticiella 2000), El Infiernillo (Jiménez- Badillo 2006) and Benito Juárez Reservoir in Oaxaca (Ramos-Cruz 1995). O. niloticus is the most commonly farmed and widely spread species due to its fast growth rate, higher fecundity and better flesh quality. Both floating surface cages and standing surface cages are used for tilapia culture. Now the pond is full of 2-5″ coppernose, so much so that I had to take remedial action in the form of stocking fifty 6-8″ largemouth and ten one- to three-pound blue cats. Nile tilapia averaged 813.8 g, a preferable size for the fillet market. INTRODUCTION F. Aeration might also on occasions be needed during the day. Species: Growth Rate Info: Growth Rate Information The following Charts will answer most of your questions about tilapia fingerlings and how they grow. they have been growing quite well. Lets suppose you put the following groups of 1,000 fish, 10 grams average for each tilapia fingerling, in a series of ponds of 1/10 Hectare each or cages 3 meters. Tilapias are mainly freshwater fish, inhabiting shallow streams, ponds, rivers and lakes, and less commonly found in brackish water. Abstract: The effect of tank background colour and stocking density on growth rates and survival of Nile tilapia (Oreochromis niloticus) fry (0.32 g) were investigated. Strep also severely reduces the appetite of the fish, thereby significantly reducing their growth rates. Resistance to Stress & … The most appropriate species or strains of tilapia for cage culture are Oreochromis niloticus (Nile tilapia), O. aurea (blue tilapia), Florida red tilapia, Taiwan red tilapia, and hybrids between these species and strains. Geographical range Oreochromis aureus is … Growth, mortality and reproduction of the blue tilapia Oreochromis aureus (Perciformes: Cichlidae) in the Aguamilpa Reservoir, Mexico December 2010 Revista de biologia tropical 58(4):1577-86 Growth Effect. However, comparative data shows that the growth of the Blue Ridge line (2.3 grams per day) compares favorably with that of other widely cultured tilapia lines. The choice of a species for culture depends mainly on avail-ability, legal status, growth rate and cold tolerance. They are also easy to breed; and they grow up to … The choice of a species for culture depends mainly on avail-ability, legal status, growth rate and cold tolerance. For example, the Nile tilapia matures at about 10 to 12 months and 3/4 to 1 pound (350 to 500 grams) in several East African lakes. For blue tilapia in Aguamilpa, estimates of b for males, females and total catch growth rate indicate a negative allometric (b <3), which is similar to reservoirs in Cuba (Fonticiella 2000), El Infiernillo (Jiménez- Badillo 2006) and Benito Juárez Reservoir in Oaxaca (Ramos-Cruz 1995). A number of different methods have been concocted to combat this problem of which three is commonly used: Raising mono-sex tilapia Excessive breeding activity tends to reduce growth rates and cause crowding. This involves buying all (almost) male fingerlings and using them in the farm. If you chose the right species or hybrids and provide a good environment it is possible to get the fish to reach a marketable size in 4-5 months. Most hybrid tilapia will stop eating at water temperatures below 16°C (61°F), The Genetically Improved Farmed Tilapia (GIFT) strain developed by the WorldFish Center as well as other strains (GET EXCEL, GenoMar ASA and GenoMar Supreme Tilapia) have a significantly better growth performance than “unaltered” strains (Asian Development Bank, 2005). An international research center in Malaysia, now known as WorldFish, began a breeding program in the 1980s that quickly doubled the growth rate of one commonly raised species, Nile tilapia. This will cause all the fish to grow slower and might even cause stunting in the fish. There is also a new method called YY male technology which is being developed but this method is not ready for use yet. GIFT and Supreme strain presented higher growth rate at 30°C of cultivation when compared to Red strain. Mean growth for the culture period of 24 days showed that feeding once a day had a higher growth at 1.48, feeding twice at 1.28, feeding thrice at 1.13 and least at 0.56 in the control treatment. T. aurea (blue Tilapia), Florida red tilapia, Taiwan red tilapia, and hybrids between these species and strains. Most commercial tilapia growers use all male stock to get more consistent growth, the males grow faster. Fish were fed with a commercial feed containing 25(Yc, protein. Copyright © 2020 Elsevier B.V. or its licensors or contributors. When using a 4-5 months growth period (sexual maturity) it is common to use 1 month old fry and stock 2,000-6,000 per acre. Keywords: blue tilapia (Oreochromis aureus); whole genome sequencing; genome assembly; genome annotation; antimicrobial peptide 1. Three duplicated batches of 29 fish [mean initial body weight 27-3 g (SE = 0-12g)], were Blue tilapia growth rate in recirculated water 183 placed in each of six tanks of 100-litre capacity, under three DO concentrations (batches 1 and 2: 2-63-12 ppm; 3 and 4: 3-75-12 ppm; and 5 and 6: 6-51 -13 ppm, or 31-3, 44-6 and 77-5% saturation, respectively). We use cookies to help provide and enhance our service and tailor content and ads. In temperate regions, it is possible to get tilapia ready for harvest by autumn. It matures in just 4 … growth performance. A pond with 8000 tilapia will give 4.4 … The tilapia survived, of course; they can tolerate lower oxygen levels than most fish. Some strains are for instance fast growing in brackish water but not very good choices in pure freshwater. In our first twenty years of business, virtually 100% of our sales have been the result of the word-of-mouth advertising of our satisfied growers. To get really large and fast growing tilapia there should be no more then 4% females in the culture. This can for instance be caused by foreign genetic material being present in the parent fish used for hybridization. They can all be eaten and will eventually reach a harvestable weight. Most mono-sex cultures are densely stocked. Female Mozambique tilapia (O. mossambicus) nearly identical, but doesn't grow as large and currently only occurs in coastal areas south of Titusville; possible hybridization between blue and Mozambique tilapias further complicates identification; male Mozambique tilapia easily distinguished by large mouth and black coloration when breeding. Temperature for Tilapia RAS farming. Don’t get fooled by advertising promoting super fast growing strains; they will only grow fast if your farm suits them. Growth rate for mono-sex cultures (all male). They can all be eaten and will eventually reach a harvestable weight. If the fish are provide with a good environment, good water quality and an adequate supply of nutrition it is possible to grow 50 gram fingerlings to become 500 gram fishes within 6 months (180 days) even without supplemental aeration if the stocking rate is 4,000/acre. You can read more about this in the article about breeding mono-sex tilapia. Most of the tilapia species grow in 32 to 34 weeks i.e. Food conversion varied from 2.4 to 3.2. Triploids of the blue tilapia were successfully produced Chourrout and Itkovich, 1983, Don and Avtalion, 1986, Penman et al., 1987, Chang et al., 1991. If your tilapia are between eight and twelve months old, their growth rate is .5% per day. Blue tilapia (Oreochromis aureus) is a species native to Northern and Western Africa, and the Middle East.In the U.S., this variety can be found abundant in Florida. A pond with 4000 fish will yield 2.2 metric ton in 180 days or 12.2 kg (27 pounds) a day. and the growth rate averaged 2.69 g/day. Water temperature directly affects the physiological processes of fish such as respiration rate, the efficiency of feeding, growth… Advantages of Monosex Tilapia Culture. Less then perfect water quality can easily cause disease and reduce growth rate in tilapia. Key words: Tilapia, salinity, growth, survival, metabolism. Though, farming of tilapia and hence, growth of tilapia depends on a lot of factors including care, atmospheric conditions, and food, etc. Superior Growth Rates. heres a little video giving an update on the growth of the tilapia. In addition, the metabolic rate of tilapia increases with increasing water salinity. Different strains of tilapia will, as earlier mentioned, grow at different rates in different environments. If you breed your own tilapia, you can add another couple of weeks for egg incubation. Standing cages are tied to stakes driven into the bottom substrate, whereas floating cages require a flotation device to stay at the surface. By continuing you agree to the use of cookies. It’s lower growth rate has severely restricted its culture to Southern Africa. 02.11.2020 vaze. Other traits. Tilapia production has increased in Aguamilpa Reservoir, in Nayarit, Mexico, in the last few years and represents a good economic activity for rural communities and the country. This research aim to know how papaya seed powder can enhance growth and survival rate of nile tilapia. On They are also a good mix of males and females for those wanting to try their hand at breeding. Pullin in his report ‘Choice of tilapia species for aquaculture’ recommended that research should concentrate on Nile tilapia and blue tilapia, not Mozambican tilapia with its slow growth rate. How to maximize your profit Compared to the tilapia varieties mentioned in this article, the Blue tilapia is the cold hardiest, being able to tolerate temperatures as low as 47 deg. The rate of growth varies from species to species and sometimes it varies even among species also. The Nile Tilapia is the most dominant species cultivated, accounting for over 90% of production. A stocking rate of 8,000/acre can yield up to 4.4 tons/acre, but will require night time emergency aeration. Under optimal conditions it can grow to 60cm, or 5kg, in around 9 years. The tilapia market may gain a stable growth rate during the forecast period of 2019-2028 owing to the escalating demand for tilapia among the global populace. A 1kg fish can be produced within 12 months however. Oreochromis aureus - Blue Tilapia. A higher number requires more work to maintain and extra aeration. T. aurea (blue Tilapia), Florida red tilapia, Taiwan red tilapia, and hybrids between these species and strains. From the specific growth rates and growth rates of the Oreochromis niloticus fingerlings fed with Blue crown ® and Skretting ® feeds, results show that the growth parameters did not vary significantly (p>0.05) in both feed treatments. Tilapia Growth Rate Chart How To Aquaponic R D Aquafarms Inc Tips And Links Wille Pille Tilapia Growth Chart A Strategic Assessment Of The Potential For Freshwater Fish ... Blue Tilapia Oreochromis Aureus Species Profile Aquaculture Wikipedia The growth rate is affected by a number of different factors that works together to decide the growth rate of tilapia, such as water quality, water temperature, the health of the fish, food supply, and oxygen levels. Blue tilapia (Oreochromis aureus), Nile tilapia (Oreochromis niloticus) and most hybrids produced from these species are good choices as they will reach a marketable size before reaching sexual maturity. The economic potentials of We determined growth parameters, mortality and reproductive aspects for 2 413 specimens of blue tilapia Oreochromis aureus in this reservoir. Introduction Tilapias are world famous for their high yields, rapid growth rates, and powerful adaptivity to various environments. The specific growth rate values of Blue tilapia indicated that supplementary feed increased the availability of all nutrients to fish when stocked in un-fertilized ponds, the lowest value was obtained by grass carp with high stocking density (T6) in un-fertilized ponds. The small bluegill also survived; small fish take less oxygen than big fish. All tilapia need fairly warm water (above 70 F) for good growth in water below 70 f they are basically hibernating. It is important to choose the right species when using this method. The means total harvest after 120 days was 450 kg/pond (3.3 T/ha/yr.). Mozambique tilapia (Oreochromis mossambicus) and Wami tilapia (Oreochromis urolepis hornorum) should be avoided as they start spawning at a very small size. A stocking rate of 8,000/acre (for a total yield of yield of 4.4 tons/acre) will for instance require night time aeration. If you use a stocking density of 4,000 fry per acre, you can expect the average size of each tilapia to be 0.5 pounds (220 grams) by harvesting time, provided that you have supplemented their diet with protein rich food. Better Flesh Quality & Appearance. Feed consumption, digestion and utilization by these fishes are also affected by the changes in water salinity. If sexually mature male and female tilapia is kept together in a tilapia farm they will start spawning if the temperature is high enough. A growth rate varying from 0.4 to 0.6 g/day was obtained. Our Aquaponics Grade blue tilapia have a more staggered growth rate to help maintain nitrifying bacteria in aquaponics systems. Blue Tilapia. It changes the age and weight at inflection point and the qualities of growth model fits, changing the variation of the batch. So called all male tilapia batches are usually not 100% male. Higher stocking rates can give even higher yields but will require constant aeration and careful water monitoring. It is also possible to produce (almost) all male batches yourself. The third commonly used method is to harvest the fish before or shortly afterward they reach sexual maturity. Tilapia growth rates are influenced by a variety of factors; water temperature, sex, supplemental feeding, and stocking density noticeably affect their growth rate. N.B! If you’re not able to provide this you should choose a lower stocking density. Tilapia are prolific breeders and can start breeding while they are still quite small. Raising tilapia in cages or tanks After this period, the growth rate flattens out for the remainder of the tilapia’s life, eventually gaining only a few ounces per year. Blue Tilapia takes much longer to reach maturity than Nile Tilapia and commonly reaches two to four pounds within three years. The blue light and long light phase (24 light hours) produced the best fish percentage weight gain (WG = 1037.8 %), specific growth rate (SGR = 4.05 %), daily growth rate (DGR = 17.3 %) and growth efficiency (GE = 0.29). If your tilapia are older than one year, feed them whatever they will eat in five minutes twice per day as their growth rate can no … It is therefore very important to choose a good strain for your particular fish farm if you want to optimize growth. The average growth rate in such a pond is 1.5-2.0 grams/day and it will take 200 days or more to get 500 gram tilapia (4.4 metric tons/acre). Densely stocked cultures are however more susceptible to disease and it is therefore important to carefully maintain the water quality. The above example means an average growth rate of 2.5 grams a day and a yield of 2.2 metric ton/acre. The amount and type of food you give your tilapia will have a dramatic effect on their growth rate – it is actually one of the most important factors – but the other factors will also have a large impact overall. The blue light was better than other colors lights, both at different photoperiods. about eight months, and the average weight of fully-grown tilapia is 450 to 600 grams. Keywords: exponential model, growth rate, supreme, GIFT, red tilapia… A pond with 8000 tilapia will give 4.4 metric ton in about 200 days, i.e. Saline Water; Published: February 2007 Population dynamics, distribution, and growth rate of tilapia (Oreochromis mossambicus) in the Salton Sea, California, with notes on bairdiella (Bairdiella icistia) and orangemouth corvina (Cynoscion xanthulus)Lucille L. Caskey 1 Getting all male tilapia can be done is a Growth comparison of Nile tilapia (Oreochromis niloticus) and Blue. Production 2002 ~ 1,350 mt . Growth of Oreochromisniloticus fingerlings and feed analysis. Certain other traits improved in response to selection because they are positively correlated with growth rate in this line. If your tilapia are over six inches, and less than eight months old, the average growth rate is 1.5% per day. Different strains grow at different pace in different environments. Tilapia have a period of accelerated growth that begins at hatching and lasts for roughly 240 days, or 34 weeks. Growth is the process of addition of flesh as a result of protein synthesis. Tilapia production has increased in Aguamilpa Reservoir, in Nayarit, Mexico, in the last few years and represents a good economic activity for rural communities and the country. There were no significant differences in initialweight, final weight, orgrowth rate between the two groups (T-Test, n =17, P =0.05). First, protein supplements may be a … In contrast to the first two varieties in the list, blue tilapia is the slowest when it comes to their growth rate. However, although mean body weight increased according to the dissolved oxygen concentration, the best food conversion ratio was shown by fish of the intermediate dissolved oxygen group. seawater and brackishwater environments may require lower protein levels for optimum growth than fish reared in fresh water. (this is the reason that up here in the upland/inland Central Florida, I prefer channel catfish over tilapia for fast growth and so I need not worry about them when we … These offspring compete with the parents for food and living space. The blue light was better than other colors lights, both at different photoperiods. As you can see the overall yield per day is much larger with a higher stocking density and will be so even if it takes more than 200 days for the fish to reach the desired size. The growth of Nile tilapia was evaluated at a stocking rate of 77 fish/m3. They are also a good mix of males and females for those wanting to try their hand at breeding. 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. It is aptly named because of its color. The choice of a species for culture depends mainly on availability, legal status, growth rate … 8th International Symposium on Tilapia in Aquaculture 2008 115 EFFECT OF BROODSTOCK SEX RATIO ON GROWTH AND REPRODUCTIVE PERFORMANCE OF BLUE TILAPIA OREOCHROMIS AUREUS (STEINDACHNER) RERED IN HAPAS KHALFALLA, M. M.1, HAMMOUDA, Y. A.2, TAHOUN, A. M.1 AND ABO-STATE H. A. M.1 1 Animal Production Dep ., Faculty of Agriculture, Kafr El-Sheikh University Kafr … The short growth period in tilapia that is being harvested before they reach sexual maturity is short and the growth rate is therefore very important to make it commercial viable to breed tilapia this way. Weight gain (g) of tilapia … The demand is mainly revolving around the beneficial nutrients and minerals it contains. Native to northern Africa and the Middle East, the Blue tilapia (Oreochromis aureus) is also known as Israeli tilapia. This is an important finding for the tilapia industry. Under good growth conditions this same species will reach sexual maturity in farm ponds at an age of 5 to 6 months and 5 to 7 ounces (150 to 200 grams). Knowledge of fish growth is of vital importance for obtaining high yield of fish. The newly hatched, called Fry, require a lot of protein for fast growth. Temperature influences weight and age at the inflection point. Like the Blue Tilapia this species has been introduced to the USA, primarily as a sport fish but also for plant control. The results ofthis study indicate that stunting has no significant effect on the growth ofmale blue tilapia when they are subsequently reared under conditions conducive togrowth. 05) between oxygen groups and actual differences regarding their specific growth rate and food conversion ratios. Hormone treated fish are not allowed to be sold on certain markets world wide and there might be restrictions on using hormones in your area. In addition to being a popular food fish it is also raised as bait fish and some aquarists keep it as a pet. If it doesn’t, you will be better of getting another strain, one that is more suitable for your fish farm. C: Tilapia start out as Omnivores but later become more like Vegetarians: The Tilapia’s digestive system is designed to eat algae, vegetation, other small fish, worms and insects. The fish were reared in aquari-um with blue, black and clear backgrounds at two stocking densities of 2 fish L-1 and 4 fish L-1. The reason mainly tilapia males are used for mono-sex culture is that they have a higher growth rate and a larger max size than females. Tolerance Environmental Fluctuations. You can expect the average weight gain to be 1.5-2.0 grams/day. Tilapia are susceptible to cold water temperatures, and will not over-winter in most temperate climates. The second method is to raise mix sex fish in cages or tanks that disrupts their breeding and thereby avoid this trouble. Blue tilapia ( Oreochromis aureus ) growth rate in relation to dissolved oxygen concentrations under recirculated water conditions Papoutsoglou, Papoutsoglou; Tziha, Tziha Influence of feeding level on growth rate of Tilapia aureus (Steindachner) reared in a closed circulated system The range of von Bertalanffy growth function parameters for cultured Nile tilapia as modelled by Moreau and Pauly (1999) were: L∞ (cm) = … Growth comparison of Nile tilapia (Oreochromis niloticus) and Blue tilapia, (Oreochromis aureus) as affected by classical and modern breeding methods The maximum recorded size is 64 cm TL (Lake Kyoga) and in Lake Turkana fish of up to 7 kg have been recorded (Trewavas, 1983). growth rate of 1.73 ±0.21g/day. In addition to factors mentioned above, the growth rate of tilapia is also affected by whether you use mono or mixed sex cultures in your farm. This is a problem in a commercial tilapia farm for obvious reasons. There is a margin of error, usually around a few percent. Harvest early 22 kg (49 pounds) a day. This design is a response to three con-siderations. As a result, our tilapia display unparalleled industry growth rates and uniformity due to superior genetics. Many states prohibit the culture of certain species. A pond with 4000 fish will yield 2.2 metric ton in 180 days or 12.2 kg (27 pounds) a day. To examine the growth characteristic of two tilapia species (blue and hornorum) in Hawaii 2. Tilapia is a very prolific fish and they produce a lot of offspring. Nile Tilapia Growth Rate Atef Mohamed Elsbaay Department of Agricultural Engineering, Faculty of Agriculture, Kfrelsheikh University, ... 16L:8D and control) and light colors (white, red and blue) were significantly affected fish growth performance. It is hard to give any general rules as to the growth rate of tilapia. Cages should be constructed from materials that are durable, lightweight and inexpensive, such as galvanized and plastic coated welded wire mesh, plastic netting and nylon netting. However, only little information about the growth of triploid tilapia is available Penman et al., 1987, Chang et al., 1991. It is concluded that the lowest feeding cost involved in tilapia controlled mass production, could be achieved with relatively low dissolved oxygen concentration, under simple recirculated water system conditions. Feeding twice had the best daily growth rate at 2.32, feeding once at 1.62, feeding thrice at 1.13 and control had the least at 0.87. About half of the harvest in each pond were unsaleable fry of less than 15 g. Again growth stopped as soon as the fish reached sexual maturity, or at 35 to 45 g mean weight. I will when discussing growth rate in mixed-sex cultures focus on cultures that are being harvested before the fish reach sexual maturity as this is a much more common practice than tank and cage breeding. Tilapia fry of uniform size of 0.76 g were released in three treatmems (stocking densities): 106 fish/m3 (T 1), 142 fish/m 3 (T 2) and 177 fish/m 3 (T;) to assess the effect of stocking density on the growth performance of fish. Tilapia are susceptible to cold water temperatures, and will not over-winter in most temperate climates. Tilapia fish are cold-blooded; the temperature of the water in which they live controls their body temperature. It is not uncommon for a 7-8 month growout in a clean facility to stretch to 10-12 months in an infected facility - and the end products of the two are like apples and oranges. Discussion. Welded wire mesh is durable, rig… x 2 meters by 1.5 meters in depth in at least a one hectare pond. Tilapia Waiwiki Specific Growth Rate Day 1 Over 14 Weeks For Monosex Growth Curves Of Nile Tilapia Oreochromis Niloticus Monosex Tilapia Aquaculture In Bangladesh Fao Tables ... Blue Tilapia Oreochromis Aureus Species Profile Aquaculture Wikipedia Several organisations have invested substantial resources in the genetic improvement of Nile tilapia. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. Many states prohibit the culture of certain species. This means that a strain that is fast growing in one location can be slower in others. This means an average growth rate of 2.5 grams per day and it is possible for such a culture to yield 2.2 tons/acre. At 22°C, Red, GIFT and Supreme strain presented similar growth and fit of exponential model. The type of farming you use can for instance affect growth rate significantly and so can stocking density. Its been one year since I got them as fry. The average growth rate in such a pond is 1.5-2.0 grams/day and it will take 200 days or more to get 500 gram tilapia (4.4 metric tons/acre). The results show that the optimum condition for farming blue tilapia, Oreochromis aureus, both with respect to growth rate and metabolic parameters is at salinities lower than 12 ppt. This is largely on account of its rapid growth, larger size and excellent eating qualities. This method means that you can not produce as large tilapia fish as you can with the other methods. Tilapia grows well in water temperatures between 60-80 degrees F and has a preference for the 80-degree end of the scale, but they are generally raised in temperatures between 72-74 degrees F to better serve up the plants.
