The Nile tilapias can live more than 10 years and reach a weight of 5 kg. Nile Tilapia (Oreochromis Niloticus) Anatomy Blue tilapias measure about 35 cm and weigh 3 kg. These nuances contrast with their light abdomen and the last portions of the fins and back, where a red tone is shown. In terms of body color it worth pointing out, that blue tilapias have blue and green metallic tones, especially at the level of the ringleader. A rather noteworthy aspect of this fish, is given by its discontinuous sideline, and a frontal part that ends around at the end of the back, starting again two or three rows of scales below. Its mouth is protractile and extended, often surrounded by bulging lips while its jaws have cone form teeth. This species has a small size compared to other tilapia fish. ![]() This type of Tilapia lives in lakes, streams, lagoons and reservoirs. The Blue Tilapia, can adapt to different and varied types of habitats: in open water as it happens in America, (where governments cultivate them in reservoirs), as well as in densely populated environments or lakes (ponds) to fatten them. They can tolerate a water temperature up to 41 degrees C (106 degrees F. Blue Tilapia, lives in both fresh and salt water, but is more common in freshwater.Īlthough it comes from tropical and subtropical areas it occurs at temperatures ranging from 8 to 30 degrees C. Since Tilapia Oreochromis aureus became a popular species for consumption, it has been introduced to many other parts or regions of the world, such as Southeast Asia and the Americas. Oreochromis aureus is native to Cameroon, Chad, Egypt, Israel, Jordan, Mali, Niger, Nigeria, Saudi Arabia and Senegal in tropical and subtropical areas of Africa and the Middle East. ![]() In the same way, they possess conical teeth pieces just as the rest of the genus. Blue tilapia (Oreochromis aureus),īlue tilapias are easy to recognize since they have swollen lips, which are quite large compared to other tilapia fish species. In more specific terms these are three large species that make up this recognized and popular genre in trade. ![]() It should be noted that the genus tilapia consists of several species. Now, all this means that tilapia feed productively and efficiently so they have the ability to capture and process a wide variety of prey as food, and all this thanks to their conical teeth.Īmong other highlights it can also be said that the tilapia fish have a relatively long dorsal fin, and a lateral line that usually lengthens towards the end of the dorsal fin can be easily distinguished along their body. In this way, their body can process food between the «true jaws» and the «pharyngeal jaws». It can also be said that tilapia fish have a group of muscle structures that allow the upper and lower pharyngeal bones to be used as a second set of very useful jaws when processing food. In the same way in terms of their anatomy, it also worth mentioning their lower pharyngeal bones that merge into a single tooth-ca rrying structure. Among other aspects immersed in the general descriptions, it should be noted that tilapia fish usually has an elongated laterally compressed body, which makes it similar to the snapper fish. ![]()
