A complete collection of tilapia species and pictures
Abstract: tilapia is a group of small and medium-sized fish, its shape and size are a little similar to crucian carp, and its fins are similar to mandarin fish. The main farmed species in China are Nile tilapia, Aulia tilapia, Mozambican tilapia and hybrid offspring of various combinations. Let's take a look at the tilapia species and pictures.
Tilapia is a group of small and medium-sized fish, its shape, body size is a bit similar to crucian carp, fins more like mandarin fish. The main farmed species in China are Nile tilapia, Aulia tilapia, Mozambican tilapia and hybrid offspring of various combinations. Let's take a look at the tilapia species and pictures.
Nile tilapia
Nile tilapia is native to eastern Africa, Jordan and other places. The edge of the dorsal fin is black, the caudal fin has obvious black stripes all its life, the throat and chest are white, the end of the caudal fin does not reach the starting point of the anal fin, there are 8-10 transverse stripes on the side of the body, there is a black spot on the back edge of the caudal stalk, and the caudal stalk is higher than the caudal handle. Nile tilapia has the advantages of fast growth, miscellaneous diet, tolerance to hypoxia, large size, high yield and high fatness, so it can be raised alone or used as hybrid parent fish in many areas of our country.
Aulia tilapia
Aulia tilapia is native to the lower reaches of the Nile in West Africa and Israel. The throat and chest are silvery gray, the dorsal fin and anal fin are dark twill, and the caudal fin is round and with silver gray spots. Aulia tilapia is more cold-tolerant, salt-tolerant, hypoxia-tolerant and higher than Nile tilapia, especially their sex chromosomes are ZW type. crossing with Nile tilapia can produce all-male tilapia, so it is often used as the male parent of crossing with Nile tilapia.
Mozambique tilapia
The difference between Mozambique tilapia and Nile tilapia is that the black stripes of the caudal fin are not vertical, the shape of the back of the head is concave, the throat and chest are dark brown, the edge of the dorsal fin is red, the end of the ventral fin can reach the starting point of the anal fin, and the height of the caudal handle is about equal to the length of the caudal handle. Due to the neglect of purification and breeding in the process of introduction, the variety was degraded and was only used as the female parent of Fushou fish hybrids.
Red tilapia
Red tilapia is an interspecific hybrid between Nile tilapia and Mozambican tilapia, with beautiful reddish and silver spots or occasional gray or black patches. Red tilapia is a kind of tilapia with fast growth rate, omnivorous, strong fecundity, wide salt, less disease, large body, beautiful body color and delicious meat. it is very popular with consumers and producers in Guangdong, Hong Kong and Macao, also known as pearl wax or cured fish.
Tilapiagalilaea
The hybrid of Aulia tilapia male and Nile tilapia female is similar to the female parent in appearance, grows fast, and the male rate is as high as 93%. It has obvious heterosis and high initial capture rate, and is now becoming the main cultured species of tilapia.
Fushou fish
The hybrid between female Mozambican tilapia and male Nile tilapia has the advantages of omnivorous, less disease, rapid growth and high yield, but the development of culture is affected by black body color and low meat content.
