Difference Between Unisexual Tilapia and Wild Tilapia

Unisexual tilapia.

Difference from wild tilapia: Unisexual tilapia (also known as Oni fish, Oysters) is a hybrid of tilapia that is close to an all-male hybrid. It grows fast, has a large individual, high male rate, neat commodity specifications, strong adaptability, and has significant benefits in increasing yield in pond aquaculture.

Feral tilapia has a flattened body with a straight or slightly raised head and a ctenophorous body; The mouth is large and the lips are thick, and the mouth is cleft in the nostrils and the eye edge.

between or extending to the rim of the eye; body color yellowish-brown, operculum with a black spot, throat and thorax white; The lateral line is broken and appears in two discontinuous rows. There are 9 black bands perpendicular to the body axis on both sides of the adult body, and there are 9 15 distinct vertical black stripes on the tail fin throughout life, and the ends are round and blunt, not bifurcated. The dorsal and anal fins also have black stripes arranged diagonally, and the edges of the dorsal fin are black.

The two look different and have different living habits.

The differences between unisexual tilapia and wild tilapia are as follows:

1.Growth rate: Unisexual tilapia has a fast growth rate, large individuals, high male rate, strong adaptability, and significant yield increase benefits in pond culture.

2.Appearance characteristics: wild tilapia has a flat body shape, a large mouth with thick lips, a black spot on the gill cover, a broken lateral line, 9 black bands on both sides of the adult body, 9 15 vertical black stripes on the tail fin for life, and black stripes arranged obliquely on the dorsal fin and anal fin.

There are clear differences between the two in terms of growth rate and physical characteristics.

Wild tilapia is not recommended.

Chinese vs. Americans' views on tilapia Tilapia can live in very dirty places, in China, in urban drains there are many of this fish, so they carry a lot of germs, so wild tilapia is not safe in China.

Tilapia, also known as: African crucian carp, non-crucian carp, and fushou fish.

This fish is widely distributed around the world and has strong adaptability, and was introduced into Guangdong as an economic fish species in the fifties of the last century. At present, Nile tilapia has been included in the third batch of China's invasive alien species list.

Why no one wants to eat wild tilapia :

At present, the larger tilapia on the market are all artificially farmed, while the wild tilapia in the rivers is generally very small in size and has a very poor meat taste, and people are reluctant to eat it after catching it. These baby tilapia are released or fed to chickens, ducks, pigs, or even used as fodder for crocodiles.

In some places, people think that the farmed tilapia is not clean, and regard tilapia as an inferior fish species with low nutritional value, but there are also places that love to eat Luo Fei fish, and the status is the same as the four major fish in our country.

The same fish species.

3 All tilapia is a group of small and medium-sized fish, its appearance and individual size are somewhat similar to crucian carp, and the fins are like mandarin fish. The main cultured species in China are Nile tilapia, Olya tilapia, Mozambique tilapia and hybrid offspring of various combinations. A hybrid of a Mozambique tilapia female and a Nile tilapia male.

It has the advantages of omnivorousness, less disease, fast growth and high yield, but it affects the development of its breeding due to its black body color and low meat content.

Hello, dear, I am happy to answer for you: how to breed unisexual tilapia After inquiry, it was learned that the suitable water temperature for unisexual tilapia breeding is 22-23, and it generally spawns naturally after mid-May.

If you lower the temperature, it won't reproduce Liang Chunchang. During the breeding process of tilapia, the female tilapia has to hold the fertilized eggs in her mouth and hatch them, hatch the small fish and then spit them out of the mori chun. In this way, the female rubber tilapia basically does not eat in the process of hatching the small fish, and the female tilapia grows slowly and small, and the meat is not tender.

Male tilapia, on the other hand, does not have the burden of this physiological process, so it grows fast and is large, and the meat is tender. Therefore, at present, people try their best to breed tilapia, and only breed unisexual (male) tilapia with high economic value, large individuality, and tender meat, especially for exported tilapia. As a farmer, we should seek tilapia fry with a high male rate, and as a fertile breeding farm that provides tilapia fry, we should breed tilapia fry with a high male rate

African crucian carp. Tilapia is native to Africa and is a tropical fish, and there are more than 100 species including subspecies of tilapia. Tilapia has the characteristics of fast generation, high yield, miscellaneous diet, few diseases, and strong fecundity. Tilapia is the main aquaculture product in China.

Its meat is delicious, less thorny, high in protein, and rich in 8 essential amino acids required by the human body, of which glutamic acid and glycine are particularly high. The nutritional evaluation of five species of tilapia, including Olya tilapia, red tilapia, gilf tilapia, Nile tilapia, and O'ni tilapia, which have relatively complete breeding and breeding systems, were evaluated.

Tilapia. The genus is native to Africa and has more than 600 species, of which 15 species are currently being farmed. Luo Feiyu is a group of small and medium-sized fish, its appearance and size are a bit similar to crucian carp, and the fins are like mandarin fish.

Broad-salt fish, which can survive in both sea and fresh water; Resistant to low oxygen, it generally inhabits the lower layer of water, but changes with the change of water temperature or the size of the fish.
