Mozambique tilapia are omnivorous. $1.50 each. It is named black tilapia in Colombia[2] and as a blue kurper in South Africa. They are often crossbred with other tilapia species in aquaculture because purebred Mozambique tilapia grow slowly and have a body shape poorly suited to cutting large fillets. [24], Aggression amongst males usually involve a typical sequence of visual, acoustic, and tactile signals that eventually escalates to physical confrontation if no resolution is reached. A review of global tilapia farming practices. Throughout courtship rituals, acoustic communication is broadly utilized by the males to draw females. [1][5] It is threatened in its home range by the introduced Nile tilapia. [14] Also, hybrids between certain parent combinations (such as between Mozambique and Wami tilapia) result in offspring that are all or predominantly male. Adults reach up to 39 cm (15 in) in standard length and up to 1.1 kg (2.4 lb). Due to their robust nature, Mozambique tilapias often over-colonize the habitat around them, eventually becoming the most abundant species in a particular area. Males do contribute by providing nests for the spawn before incubation, but the energy costs associated with nest production is low relative to mouthbrooding. Dominant males signal females through the use of a urinary odorant. Mozambique tilapia are proof against large forms of water high-quality points and air pollution ranges. One of many prices related to this synchronization is the rise in competitors amongst males, that are already excessive on the dominance hierarchy. Snakehead Murrel Fish | Food | Nutrition | Farming, Mangrove Red Snapper Facts | Size | Description. [28] These proficient reproductive strategies may be the cause behind their invasive tendencies. On account of their sturdy nature, Mozambique tilapias usually over-colonize the habitat round them, ultimately turning into probably the most considerable species in a selected space. 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. When over-crowding occurs and assets get scarce, adults will typically cannibalize the younger for extra vitamins. Male tilapia are preferred in aquaculture as they grow faster and have a more uniform adult size than females. Then the female stores the eggs in her mouth until the fry hatch; this act is called mouthbrooding. In poorly fertilised ponds sexually mature Mozambique tilapia may be as small as 1/2 ounce (15 grams). Mozambique type doesn’t grow as fast as other varieties but has been found useful in producing hybrids. When over-crowding happens and resources get scarce, adults will sometimes cannibalize the young for more nutrients. Urinary pheromones also play a part in male – male interaction for Mozambique tilapias. Hormones and pheromones launched with urine by the fish usually have an effect on the conduct and physiology of alternative intercourse. Dominant males additionally construct bigger nests for the spawn. Likewise, one other technique for males is to exist as a floater, traveling between territories in an try to discover a mate. Studies have shown that females are attracted to dominant males who produce lower peak frequencies as well as higher pulse rates. It might probably hurt native fish populations by way of competitors for meals and nesting houses, in addition to by straight consuming small fish. Parental care is, subsequently, virtually unique to the feminine. They have a mild, white flesh that is appealing to consumers.

WorldFish Center P.O. [30] Even with oocyte arrest, females that mouthbrood take significant costs in body weight, energy, and low fitness. Native coloration is a uninteresting greenish or yellowish, and weak banding could also be seen. Acosta. Mozambique tilapia are similar to, and could be mistaken for, two other introduced cichlids: blue tilapia O. aureus and Nile tilapia O. niloticus. This hybrid is the result of crossing a unique variant of Mozambique tilapia (Oreochromis mossambicus) with a specially developed Wami tilapia (Oreochromis urolepis hornorum). Thus, cheating is prevented by the sheer fact that the costs of initiating a ritual often outweigh the benefits of cheating. Native coloration is a uninteresting greenish or yellowish, and weak banding could also be seen. [32] Tilapia are very susceptible to diseases such as whirling disease and ich. These similar options make it a great species for aquaculture as a result of it readily adapts to new conditions. Within the lek system, males congregate and show themselves to draw females for matings. A mature male tilapia grows to 30-44 cm in length and a mature female grows to about 25-33 cm. [1], Otherwise it is a remarkably robust and fecund fish, readily adapting to available food sources and breeding under suboptimal conditions. The designation of Mozambique tilapias as an invasive species rests on their life-history traits: Tilapias exhibit excessive ranges of parental care in addition to the capability to spawn a number of broods by way of a prolonged reproductive season, each contributing to their success in various environments. Inland fishes of California. [4][7] Among others, it occurs in rivers, streams, canals, ponds, lakes, swamps and estuaries, although it typically avoids fast-flowing waters, waters at high altitudes and the open sea.

In comparison with nonmouthbrooders, each mouthbrooding and rising a brand new clutch of eggs will not be energetically possible. Because of these abilities they have been used as bioassay organisms to generate metal toxicity data for risk assessments of local freshwater species in South Africa rivers.[33]. It is a popular fish for aquaculture. Males may mimic females and sneak reproduction attempts when the dominant male is occupied. Mozambique Tilapia has been studied in many countries around the world. Dominant males both store and release more potent urine during agonistic interactions. It lives up to 11 years. The Mozambique Tilapia is found in many different waters, with the exception of fast-flowing rivers and streams. Tilapia are very prone to illnesses reminiscent of whirling illness and ich. Sometimes, Mozambique tilapias, like all species belonging to the genus Oreochromis and species like Astatotilapia burtoni, are maternal mouthbrooders, which means that spawn is incubated and raised within the mouth of the mom.

mozambique tilapia size

Therefore, the parental-offspring battle is seen by way of the prices and advantages to the dad and mom and the younger. Management of exotic species in natural communities. WILL SHIP 1-2 BUSINESS DAYS. The native Mozambique tilapia is laterally compressed and has a deep physique with lengthy dorsal fins, the entrance a part of which has spines. 1976. Common Carp Facts – How Fast do Carp Grow. These proficient reproductive methods will be the trigger behind their invasive tendencies. [16][17] This broad diet helps the species thrive in diverse locations. Due to these talents, they’ve been used as bioassay organisms to generate metallic toxicity knowledge for danger assessments of native freshwater species in South Africa rivers. The hybrids grow faster, have a better body shape, and in some species the populations will be predominantly male (which will grow faster to a uniform size). The population of hybrid Mozambique tilapia x Wami tilapia in California's Salton Sea may also be responsible for the decline of the desert pupfish, Cyprinodon macularius. [4] Size and coloration may vary in captive and naturalized populations due to environmental and breeding pressures. In addition to competing for the same resources, the two readily hybridize. Courtenay W.R. Jr. 1989. 330 p. Popma, T. Tilapia Life History and Biology 1999 Southern Region Aquaculture Center. Males do contribute by offering nests for the spawn earlier than incubation, however, the vitality prices related to nest manufacturing are low relative to mouthbrooding. Pages 237–252 in: Thomas L.K. The native Mozambique tilapia is laterally compressed, and has a deep body with long dorsal fins, the front part of which have spines. [20] In terms of social structure, Mozambique tilapias engage in a system known as lek-breeding, where males establish territories with dominance hierarchies while females travel between them. At the end of mating, males guard the nest while females take both the eggs and the sperm into their mouth. Native coloration is a dull greenish or yellowish, and weak banding may be seen. University of California Press, Berkeley, CA. Mozambique tilapia is laterally compressed, and has a deep body with long dorsal fins, the front part of which have spines. Mozambique tilapias have been identified to learn to feed themselves utilizing demand feeders. Tilapia populations in large lakes mature at a later age and larger size than the same species raised in small farm ponds. Male Mozambique tilapias synchronize breeding behavior in terms of courtship activity and territoriality in order to take advantage of female spawning synchrony. Though primarily a fish of contemporary and brackish waters, it could stay in saltwater, and even in hypersaline situations the place the salinity may be about thrice as excessive as seawater. The Mozambique Tilapia is considered a freshwater species but it can be found in both estuaries and coastal lakes, especially in the southern part of its geographical range. The Mozambique tilapia has been nominated by the Invasive Species Specialist Group as one of many 100 worst invasive species on the planet. In step one within the reproductive cycle for Mozambique tilapia, males excavate a nest into which a feminine can lay her eggs. They can consume detritus, diatoms, invertebrates, small fry and vegetation ranging from macroalgae to rooted plants. They have got a gentle, white flesh that’s interesting to customers. Then the feminine shops the eggs in her mouth till the fry hatch; this act is named mouthbrooding. The inhabitants of hybrid Mozambique tilapia x Wami tilapia in California’s Salton Sea may additionally be chargeable for the decline of the desert pupfish, Cyprinodon macularius. This has already been documented from the Zambezi and Limpopo Rivers, and it’s anticipated that pure Mozambique tilapia ultimately will disappear from each.In any other case it’s a remarkably sturdy and fecund fish, readily adapting to obtainable meal sources and breeding below suboptimal situations. It inhabits waters that vary from 17 to 35 °C (63–95 °F).

[26] One of the main reasons behind the aggressive actions of Mozambique tilapias is access to reproductive mates. Uninteresting colored, the Mozambique tilapia usually lives as much as a decade in its native habitats. Adults attain as much as 39 cm (15 in) in customary size and as much as 1.1 kg (2.Four lb). Required fields are marked *. Adults reach approximately 35 cm (14 in) in length and up to 1.13 kg (2.5 lb). During the breeding season, males cluster around certain territory, forming a dense aggregation in shallow water. [8] The Mozambique tilapia has been nominated by the Invasive Species Specialist Group as one of the 100 worst invasive species in the world. This species constitutes about 4% of the full tilapia aquaculture manufacturing worldwide, however, is extra generally hybridized with different tilapia species. Positions within the hierarchy correlate with territoriality, courtship rate, nest size, aggression, and hormone production. This has already been documented from the Zambezi and Limpopo Rivers, and it’s anticipated that pure Mozambique tilapia ultimately will disappear from each. Three of the most commonly fished and eaten species of Tilapia are Nile, Blue and Mozambique. Thus, males that are higher ranked initiate much more aggressive acts than subordinate males. The Mozambique tilapia is native to inland and coastal waters in southeastern Africa, from the Zambezi basin in Mozambique, Malawi, Zambia, and Zimbabwe to Bushman River in South Africa’s Japanese Cape province. It’s a common fish for aquaculture. Trewevas E. 1983. Size and coloration may vary in captive and naturalized populations due to environmental and breeding pressures. Throughout business feeding, the fish might energetically bounce out of the water for meals. A mature male tilapia grows to 30-44 cm in length and a mature female grows to about 25-33 cm. A mother caring for her offspring carries the cost of reducing her own individual fitness. Social hierarchies typically develop because of competition for limited resources including food, territories, or mates. On account of human introductions, it’s now discovered in lots of tropical and subtropical habitats across the globe, the place it could turn into an invasive species due to its sturdy nature. Average Size: 1/2" - 1". Dominant males also build larger nests for the spawn. Dominant males sign females by way of the usage of a urinary odorant. Further studies have suggested that females respond to the ratio of chemicals within the urine, as opposed to the odor itself. Due to this, Mozambique tilapias can occupy many niches during spawning since the young can be transported in the mouth. Due to human introductions, it is now found in many tropical and subtropical habitats around the globe, where it can become an invasive species because of its robust nature. The Mozambique Tilapia, is more commonly used for hybridization with other tilapia species. (ed.). In this regard, differences between individuals in endurance plays a critical role in resolving the winner and the loser.[25]. [18] Feeding patterns vary depending on which food source is the most abundant and the most accessible at the time. The "Florida Red" tilapia is a popular commercial hybrid of Mozambique and blue tilapia.[15]. It lives as much as 11 years. In captivity, Mozambique tilapias have been known to learn how to feed themselves using demand feeders. One of the costs associated with this synchronization is the increase in competition among males, which are already high on the dominance hierarchy. (1982) and Page and Burr (1991). In the first step in the reproductive cycle for Mozambique tilapia, males excavate a nest into which a female can lay her eggs. Thus, mating success is very skewed in the direction of dominant males, who are typically bigger, extra aggressive, and simpler at defending territories. (2019). Notify me when this product is available: Black Mozambique Tilapia Fingerlings. In Hawaii, striped mullet Mugil cephalus is threatened due to the introduction of this species. Varying in shape, size and color, these three fish differ from one another in more ways than just how they look. As a result, different mating tactics have evolved in these species. [1][4] It inhabits waters that range from 17 to 35 °C (63–95 °F). It is known to appreciate standing water. This broad food regimen helps the species thrive in numerous places. After the eggs are laid, the male fertilizes them. In captivity. It is known as black tilapia in Colombia[2] and as blue kurper in South Africa. After the eggs are laid, the male fertilizes them. [22], In experiments with captive tilapias, evidence demonstrates the formation of linear hierarchies where the alpha male participates in significantly more agonistic interactions. [21] During courtship rituals, acoustic communication is widely used by the males to attract females. Along with competing for similar assets, the 2 readily hybridize. Research has proven that females are drawn to dominant males who produce decrease peak frequencies in addition to increased pulse charges. Even with oocyte arrest, females that mouthbrooding takes vital prices in physique weight, vitality, and low health. The Mozambique tilapia or hybrids involving this species and different tilapia are invasive in lots of components of the world outdoors their native vary, having escaped from aquaculture or been intentionally launched to manage mosquitoes. [4][7], The Mozambique tilapia or hybrids involving this species and other tilapia are invasive in many parts of the world outside their native range, having escaped from aquaculture or been deliberately introduced to control mosquitoes. In this context, members of this social system tend to avoid confrontations with neighboring ranks in order to conserve resources rather than engage in an unclear and risky fight. Although primarily a fish of fresh and brackish waters, it can live in salt water and even in hypersaline conditions where the salinity can be about three times as high as seawater. Mozambique tilapia, like different fish reminiscent of Nile tilapia and trout, are opportunistic omnivores and can feed on algae, plant matter, natural particles, small invertebrates, and different fish. Symmetrical aggression between males resulted in an increase in the release of urination frequency. Likewise, another strategy for males is to exist as a floater, travelling between territories in an attempt to find a mate. Mozambique tilapia sizes may vary, but adults can weigh up to 2.4 pounds and reach 15 inches in length. Native coloration is a dull greenish or yellowish, and weak banding may be seen. x Oreochromis mossambicus)", "Culture of Hybrid Tilapia: A Reference Profile", "Biology and ecology of Mozambique tilapia (Oreochromis mossambicus)", "Oreochromis mossambicus (Mozambique Tilapia)", "Male urine signals social rank in the Mozambique tilapia (Oreochromis mossambicus)", "Acute toxicity of selected heavy metals to, https://en.wikipedia.org/w/index.php?title=Mozambique_tilapia&oldid=975404756, Creative Commons Attribution-ShareAlike License. In any other case it’s a remarkably sturdy and fecund fish, readily adapting to obtainable meal sources and breeding below suboptimal situations. [31], Mozambique tilapia are hardy individuals that are easy to raise and harvest, making them a good aquacultural species. This species constitutes about 4% of the total tilapia aquaculture production worldwide, but is more commonly hybridized with other tilapia species. Mozambique Tilapia has been studied in many countries around the world. On the finish of mating, males guard the nest whereas females take each the eggs and the sperm into their mouth. Hence, parental-offspring conflict is visible through the costs and benefits to the parents and the young. Thus, mating success is highly skewed towards dominant males, who tend to be larger, more aggressive, and more effective at defending territories. However, Mozambique tilapia have the desirable trait of being especially tolerant of salty water. [9] It can harm native fish populations through competition for food and nesting space, as well as by directly consuming small fish. Not like most fish, Mozambique tilapias exhibit a prolonged maternal care interval believed to permit social bonds to be fashioned. Tilapiine Fishes Of The Genera Sarotherodon, Oreochromis And Danakilia. [1][6] This has already been documented from the Zambezi and Limpopo Rivers, and it is expected that pure Mozambique tilapia eventually will disappear from both. Native coloration is a dull greenish or yellowish, and weak banding may be seen. Nevertheless, females are known to be able to distinguish between hierarchical rank and dominant vs. subordinate males through chemicals in urine. One of many most important causes behind the aggressive actions of Mozambique tilapias is entry to reproductive mates. Robins. One hypothesis behind this action rests with the fact that aggressive actions are costly. Box 500 GPO, 10670, Penang, Malaysia. Studies have shown that male aggression is highly correlated with increased urination. and B.O. Due to these talents, they’ve been used as bioassay organisms to generate metallic toxicity knowledge for danger assessments of native freshwater species in South Africa rivers.Source, Your email address will not be published. On account of this, Mozambique tilapias can occupy many niches throughout spawning for the reason that younger may be transported within the mouth. Adults reach up to 39 cm (15 in) in standard length and up to 1.1 kg (2.4 lb). Sexual maturity in tilapia is a function of age, size and environmental conditions. Urine in Mozambique tilapias, like many freshwater fish species, acts as a vector for communication amongst people. Fish introductions: Good management, mismanagement, or no management? Tilapia (/ t ɪ ˈ l ɑː p i ə / tih-LAH-pee-ə) is the common name for nearly a hundred species of cichlid fish from the coelotilapine, coptodonine, heterotilapine, oreochromine, pelmatolapiine and tilapiine tribes (formerly all were "Tilapiini"), with the economically most important species placed in Coptodonini and Oreochromini. In consequence, completely different mating ways have developed in these species. On the other hand, a male tilapia becomes sexual maturity at 10-30 cm in length. Bodily damage may impede an individual's ability to find a mate in the future. The Mozambique tilapia (Oreochromis mossambicus) is an oreochromine cichlid fish native to southeastern Africa. U.S. National Park Service and George Wright Society, Washington, D.C. Courtenay W.R. Jr., and C.R. Hormones and pheromones released with urine by the fish often affect the behavior and physiology of the opposite sex. Instead, dominant individuals seek to bully subordinate tilapias both for an easy fight and to keep their rank.[23]. [3], The native Mozambique tilapia is laterally compressed, and has a deep body with long dorsal fins, the front part of which have spines. Dimension and coloration might fluctuate in captive and naturalized populations attributable to environmental and breeding pressures. [4], The Mozambique tilapia is native to inland and coastal waters in southeastern Africa, from the Zambezi basin in Mozambique, Malawi, Zambia and Zimbabwe to Bushman River in South Africa's Eastern Cape province. In order to prevent cheating, in which individual may fake his own fitness, these aggressive rituals incur significant energetic costs. Mozambique tilapia are hardy people which can be simple to boost and harvest, making them a great aquacultural species. Thus, Mozambique tilapias arrest oocyte development throughout mouthbrooding to preserve vitality. Usually, conflict ends before physical aggression as fights are both costly and risky. Black Mozambique Tilapia Fingerlings $1.50 each Average Size: 1/2" - 1" WILL SHIP 1-2 BUSINESS DAYS MONDAY THROUGH WEDNESDAY These proficient reproductive methods will be the trigger behind their invasive tendencies. Thus, Mozambique tilapias arrest oocyte growth during mouthbrooding to conserve energy. Compared to nonmouthbrooders, both mouthbrooding and growing a new clutch of eggs is not energetically feasible. [19], Mozambique tilapias often travel in groups where a strict dominance hierarchy is maintained. Under good growing conditions in ponds, the Mozambique tilapia may reach sexual maturity in as little as 3 months of age, when they seldom weigh more than 2 to 4 ounces (60 to 100 grams). Actinopterygii (ray-finned fishes) > Perciformes (Perch-likes) > Cichlidae (Cichlids) > Pseudocrenilabrinae Etymology: Oreochromis: Latin, aurum = gold + Greek, chromis = a fish, perhaps a perch (Ref. Mozambique tilapia are omnivorous. $1.50 each. It is named black tilapia in Colombia[2] and as a blue kurper in South Africa. They are often crossbred with other tilapia species in aquaculture because purebred Mozambique tilapia grow slowly and have a body shape poorly suited to cutting large fillets. [24], Aggression amongst males usually involve a typical sequence of visual, acoustic, and tactile signals that eventually escalates to physical confrontation if no resolution is reached. A review of global tilapia farming practices. Throughout courtship rituals, acoustic communication is broadly utilized by the males to draw females. [1][5] It is threatened in its home range by the introduced Nile tilapia. [14] Also, hybrids between certain parent combinations (such as between Mozambique and Wami tilapia) result in offspring that are all or predominantly male. Adults reach up to 39 cm (15 in) in standard length and up to 1.1 kg (2.4 lb). Due to their robust nature, Mozambique tilapias often over-colonize the habitat around them, eventually becoming the most abundant species in a particular area. Males do contribute by providing nests for the spawn before incubation, but the energy costs associated with nest production is low relative to mouthbrooding. Dominant males signal females through the use of a urinary odorant. Mozambique tilapia are proof against large forms of water high-quality points and air pollution ranges. One of many prices related to this synchronization is the rise in competitors amongst males, that are already excessive on the dominance hierarchy. Snakehead Murrel Fish | Food | Nutrition | Farming, Mangrove Red Snapper Facts | Size | Description. [28] These proficient reproductive strategies may be the cause behind their invasive tendencies. On account of their sturdy nature, Mozambique tilapias usually over-colonize the habitat round them, ultimately turning into probably the most considerable species in a selected space. 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. When over-crowding occurs and assets get scarce, adults will typically cannibalize the younger for extra vitamins. Male tilapia are preferred in aquaculture as they grow faster and have a more uniform adult size than females. Then the female stores the eggs in her mouth until the fry hatch; this act is called mouthbrooding. In poorly fertilised ponds sexually mature Mozambique tilapia may be as small as 1/2 ounce (15 grams). Mozambique type doesn’t grow as fast as other varieties but has been found useful in producing hybrids. When over-crowding happens and resources get scarce, adults will sometimes cannibalize the young for more nutrients. Urinary pheromones also play a part in male – male interaction for Mozambique tilapias. Hormones and pheromones launched with urine by the fish usually have an effect on the conduct and physiology of alternative intercourse. Dominant males additionally construct bigger nests for the spawn. Likewise, one other technique for males is to exist as a floater, traveling between territories in an try to discover a mate. Studies have shown that females are attracted to dominant males who produce lower peak frequencies as well as higher pulse rates. It might probably hurt native fish populations by way of competitors for meals and nesting houses, in addition to by straight consuming small fish. Parental care is, subsequently, virtually unique to the feminine. They have a mild, white flesh that is appealing to consumers.

WorldFish Center P.O. [30] Even with oocyte arrest, females that mouthbrood take significant costs in body weight, energy, and low fitness. Native coloration is a uninteresting greenish or yellowish, and weak banding could also be seen. Acosta. Mozambique tilapia are similar to, and could be mistaken for, two other introduced cichlids: blue tilapia O. aureus and Nile tilapia O. niloticus. This hybrid is the result of crossing a unique variant of Mozambique tilapia (Oreochromis mossambicus) with a specially developed Wami tilapia (Oreochromis urolepis hornorum). Thus, cheating is prevented by the sheer fact that the costs of initiating a ritual often outweigh the benefits of cheating. Native coloration is a uninteresting greenish or yellowish, and weak banding could also be seen. [32] Tilapia are very susceptible to diseases such as whirling disease and ich. These similar options make it a great species for aquaculture as a result of it readily adapts to new conditions. Within the lek system, males congregate and show themselves to draw females for matings. A mature male tilapia grows to 30-44 cm in length and a mature female grows to about 25-33 cm. [1], Otherwise it is a remarkably robust and fecund fish, readily adapting to available food sources and breeding under suboptimal conditions. The designation of Mozambique tilapias as an invasive species rests on their life-history traits: Tilapias exhibit excessive ranges of parental care in addition to the capability to spawn a number of broods by way of a prolonged reproductive season, each contributing to their success in various environments. Inland fishes of California. [4][7] Among others, it occurs in rivers, streams, canals, ponds, lakes, swamps and estuaries, although it typically avoids fast-flowing waters, waters at high altitudes and the open sea. [27] In the lek system, males congregate and display themselves to attract females for matings. These same features make it a good species for aquaculture because it readily adapts to new situations. "Listado oficial de especies invasoras para Colombia | Parques Nacionales Naturales de Colombia", "Molecular phylogeny of Oreochromis (Cichlidae: Oreochromini) reveals mito-nuclear discordance and multiple colonisation of adverse aquatic environments", "Genes for sexual body size dimorphism in hybrid tilapia (Oreochromis sp. In comparison with nonmouthbrooders, each mouthbrooding and rising a brand new clutch of eggs will not be energetically possible. Because of these abilities they have been used as bioassay organisms to generate metal toxicity data for risk assessments of local freshwater species in South Africa rivers.[33]. It is a popular fish for aquaculture. Males may mimic females and sneak reproduction attempts when the dominant male is occupied. Mozambique Tilapia has been studied in many countries around the world. Dominant males both store and release more potent urine during agonistic interactions. It lives up to 11 years. The Mozambique Tilapia is found in many different waters, with the exception of fast-flowing rivers and streams. Tilapia are very prone to illnesses reminiscent of whirling illness and ich. Sometimes, Mozambique tilapias, like all species belonging to the genus Oreochromis and species like Astatotilapia burtoni, are maternal mouthbrooders, which means that spawn is incubated and raised within the mouth of the mom.
