African crucian carp, is it not allowed to eat?

Tilapia, commonly known as African crucian carp. Native to Africa, it 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. 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.

Tilapia has a wide range of diets, most of which are plant-based omnivorous, very poor food, and large food intake; It grows rapidly, especially in the juvenile stage. The growth temperature of Luofei fish is closely related to temperature, the growth temperature is 16 38, and the suitable temperature is 22 35. Tilapia was first introduced to Taiwan Province in 1946 by Wu Zhenhui and Guo Qiyan from Singapore, and in honor of these two people, it was first called "Wu Guo Fish".

In 1957, it was introduced from Vietnam to the mainland of China, also known as "Vietnamese fish". Because it is native to Africa and resembles the native crucian carp, some people call it "African crucian carp". There are two types of tilapia introduced to Yingshan Hot Spring in Hubei Province:

One is called Mozambique tilapia, which was brought to Yingshan Hot Spring from Jingshan County in 1972; The other is called Nile tilapia, which was introduced by the Hubei Provincial Fisheries Research Institute in 1979. After they settled down, they all lived well. Dr. Modadugu Vijay Gupta of India was awarded the 2005 World Food Prize for the development and dissemination of cheap techniques for clear-water aquaculture (using tilapia).

Cooking Instruction 1Tilapia is best braised and steamed; 2.Clever to remove the fishy smell:

1. After the fish is scaled and washed, pour some rice wine into the basin, which can remove the fishy smell of the fish and make the fish taste delicious; 2. Cut the fresh fish and wash it, and soak it in milk for a while to remove the smell and increase the umami; 3. After eating fish, when there is a taste in the mouth, chew three or five pieces of tea leaves, and immediately fresh breath;

Tilapia, commonly known as African crucian carp, belongs to the order Perch, Perciformes, Cichlidae, and Tilapia (also known as the cichlidae, cichlidae). The genus is native to Africa and has more than 600 species, of which 15 species are currently being farmed. The meat of tilapia is delicious and tender, and it tastes great whether it is braised or cooked.

Nile tilapia has been determined to contain grams of protein, grams of fat, calories 148 kcal, calcium 70 mg, sodium 50 mg, phosphorus 37 mg, iron 1 mg, vitamin B1 mg, vitamin B2 mg per 100 grams of meat. Tilapia has become the main farmed fish worldwide.

African crucian carp is tilapia.

Tilapia, native to Africa, is also known as African crucian carp. In China, aquaculture is mainly concentrated in Guangdong, Guangxi, Hainan and other areas with high temperature, most of which are intensive pond culture. Tilapia is not only delicious, glutamate.

The content of glycine is also particularly high, and it is deeply loved by people.

Tilapia is a tropical fish, and there are more than 100 species of tilapia, including subspecies. Tilapia has the characteristics of fast generation, high yield, miscellaneous diet, few diseases, and strong fecundity. In addition to domestic sales, some enterprises use tilapia to make fish fillets, fish steaks, etc., which are exported to foreign countries, which are excellent aquaculture species.

Habits:

Tilapia inhabits the pelagic pelagic and is an omnivorous fish based on plant-based feeds. Tilapia is not tolerant to low temperatures and will freeze to death at a water temperature of about 10.

Some species of tilapia have oral hatching behavior, in which the female holds the fertilized eggs in her mouth until they hatch into juveniles, which is very beneficial for her reproduction. In some species of tilapia, before breeding, males dig the subsoil to build pot-shaped nests, which have a strong territoriality, and the females lay their eggs in the nests, and after hatching, the females will hold the juveniles in their mouths for protection.

In fact, there are many people who eat African crucian carp. African crucian carp, i.e. tilapia, is native to Africa and is a tropical fish, which has the characteristics of fast generation, high yield, miscellaneous diet, few diseases, and strong fecundity. Tilapia is the main aquaculture product in China, because of its delicious meat, less spines, high nutritional value and is deeply loved by people, known as "white meat salmon", "21st century fish" said.

The tilapia raised in China include Qi's tilapia, Nile tilapia, Mozambique tilapia, yellow-edged black tilapia, orlie steak sedan tilapia, etc., as well as hybrid varieties of O'Ni tilapia, red tilapia and Fushou tilapia.

The cultivation area of tilapia is mainly concentrated in Guangji, Guangxi, Hainan and other areas with high temperature, and is mainly intensively cultivated in ponds. In addition to domestic sales, some enterprises will use tilapia to make fish fillets, fish steaks, etc. for export abroad, which is an excellent aquaculture species.

The vast majority of tilapia are omnivorous and often eat plants and debris in the water. This fish can breed even in small waters. It can even grow in rice fields.

It usually lives in fresh water, but can also live in saltwater with different salt content, and can survive in shallow water in lakes, rivers, and ponds.

Captive-breeding: 1 fingerling reared.

The pond area is 667-3333 square meters (1-5 acres), and the pond is cleaned and disinfected about half a month before the seedlings are released, and then water is injected, and the water depth is controlled in meters. About 500 kg of manure and green manure are applied every 667 square meters as base fertilizer to keep the transparency of the pool water at about 25 cm. About 100,000 seedlings are placed every 667 square meters, and in addition to applying base fertilizer, soybean milk is sprinkled every day to feed the seedlings to strengthen the seedlings.

At a water temperature of about 25, after 15-20 days of cultivation, the fry can grow to about 1 gram, and the fry can be raised in time for feeding commercial fish.

2 Commercial fish rearing.

Pond rearing of Fushou fish is the same as that of other tilapia rearing techniques, and a variety of rearing modes can be used. However, at that time, the promotion was dominated by polyculture. This refers to the fact that the four major fish are mainly raised, and the Fushou fish is only raised as a matching species.

In ponds that are generally used to raise fatty water fish, stocking can be carried out according to the water temperature, as long as the water temperature can be maintained stably above 18.

3 Stocking specifications.

The small is 5-15 grams, the large can be stocked with 25-30 grams, and the size of the early seedlings is smaller, but it should not be less than 3 grams. The stocking density generally depends on the size of the seed and the seed. As an adult fish pond dominated by four large fish, 200-1000 Fushou fish can be stocked per 667 square meters.

The fry hatched in that year, reared for 150 days, the individual can reach 150-250 grams, and the four large fish are polycultured, and the individual yield is as high as 150-500 kg per 667 square meters.

African crucian carp is not poisonous.

African crucian carp is tilapia, the meat is delicate, the taste is fresh and the meat is delicious, and there are few spines, no small spines between the muscles, whether it is braised or steamed, the taste is good, and it is deeply loved by the public. Tilapia is flat in nature, sweet in taste, can benefit the spleen and stomach, nourish the liver and kidneys, and has a therapeutic effect on indigestion, diarrhea, thin yellow muscles, edema, muscle and bone weakness and other diseases.

Tilapia is extremely nutritious and comprehensive, rich in high-quality protein and essential amino acids; Tilapia is low in fat, and most of the fat contained in it is polyunsaturated fatty acids, which lowers blood lipids, invigorates blood vessels, and is beneficial to cardiovascular health; In addition, tilapia is rich in trace elements such as calcium, iron, zinc and B vitamins, which can enhance the body's energy metabolism and anabolism.

1.Tilapia introduced.

Tilapia (tilapia) is a fish that grows in freshwater and is often referred to as African crucian carp. This fish is large in size, up to 100 centimeters in size, and is very common in African lakes. Due to its adaptability, tilapia has been introduced to many countries for farming, making it one of the most important freshwater species in the world.

2.Difference Between Tilapia and Crucian Carp.

Although tilapia is known as African crucian carp, the two fish are not actually exactly the same. In terms of scientific name, the scientific name of crucian carp is carassius auratus, while the scientific name of tilapia is tilapia. In appearance, crucian carp are usually smaller and stocky in size, while tilapia are longer and flattened.

Also, tilapia has a larger head and a more prominent mouth.

3.Tilapia farming.

Tilapia is an adaptable fish that is not environmentally demanding and suitable for freshwater farming. When cultivating tilapia, it is necessary to pay attention to the maintenance of water quality, the control of water temperature, and the quality of feed. In general, tilapia prefers to grow in water with a temperature of 25 to 30 degrees Celsius, suitable for an environment with a pH of 7 to 8.

4.The edible value of tilapia.

Tilapia is not only suitable for farming, but it is also a delicious ingredient. Tilapia is rich in high-quality protein, trace elements and other nutrients, which can provide the energy needed by the human body. When eating dry tilapia, you need to pay attention to remove the internal organs, scales and spines, and it is best to soak it in water and a small amount of salt, and then add some condiments for cooking.

5.The relationship between tilapia and the ecological environment.

Tilapia is adaptable and can live in a variety of environments, but it also has an impact on the environment. Since tilapia likes to eat small fish and shrimp, it will have a certain impact on the ecosystem in the lake. In addition, if the water quality is not properly controlled during the breeding process, it may also cause environmental pollution.

Therefore, when carrying out tilapia farming activities, it is necessary to make scientific and reasonable planning, rational use of resources, and protection of the ecological environment.

6.Summary.

Tilapia is an adaptable freshwater fish that is popular for its fast growth and delicious taste. Although tilapia is called African crucian carp, the two fish are not exactly the same. When carrying out tilapia farming activities, it is necessary to pay attention to environmental protection, scientific and rational planning, and rational use of resources.

At the same time, it is also necessary to pay attention to food safety when eating tilapia, and remove internal organs, scales and spines to avoid health effects.
