Knowledge about Tilapia

   Tilapia are known for their rapid growth, environmental tolerance, and ease of rearing, making them widely farmed and introduced to many warm freshwater and brackish water areas worldwide. They typically inhabit shallow waters such as lakes, rivers, and ponds, but can also survive in small bodies of water or rice paddies. They are euryhaline, meaning they can live in varying salinity levels in estuaries and nearshore areas. They can adapt to temperatures from 12-45°C and have a strong ability to thrive, especially in waters with low dissolved oxygen. This has led to them becoming an invasive species in many places and being listed among the world's top 100 invasive alien species. Most tilapia are omnivorous, feeding primarily on aquatic plants and detritus.

   Tilapia have a laterally compressed body, a high back, and a thick body, resembling a mandarin fish or a sea bream in appearance. Their bodies are covered in cycloid scales. They have a small head, a large mouth, thick lips, and sharp, fine teeth inside the mouth, but no barbels. Their dorsal and anal fins have hard spines, and the fin rays are strong and sharp, with black and white spots. Tilapia primarily inhabit the middle and lower layers of water, and their activity range varies with their size and water temperature. Tilapia exhibit a certain diurnal activity pattern: in the early morning, as the water temperature gradually rises, they often swim in groups in the middle and lower layers; at midday, they rise to near the surface, quickly diving back down when disturbed; from afternoon to evening, they gradually sink to the middle and lower layers; and at night, they remain at the bottom.

   Tilapia is an important edible fish, prized for its delicious flesh, dense muscle fiber structure, few intramuscular bones, and rich content of protein, amino acids, and minerals. More than ten species are widely farmed. It can also be processed into viscerated tilapia, tilapia fillets, etc.
