The Egyptian beard owl is also known as the Egyptian pond catfish and the leather beard owl. Native to the Nile Valley in Africa, it is one of the local freshwater economic fish. China's introduction of trials in 1981 has achieved good breeding results and is currently being promoted in large areas. A variety of water bodies can be used for breeding Egyptian beard owls, such as ponds, cement pools, shallow ponds, and water cluster boxes. It is suitable for high-density feeding, and the stocking amount can be several times higher than other fishes, and the breeding cycle is short, the yield is high, and it can be captured many times a year. Therefore, it is a good way for farmers to raise fish to become rich.

Egyptian beard quail has the characteristics of tender meat, delicious taste, less spurs, and high nutritional value. It is a high-quality aquatic product that consumers like to eat. Its fast growth, large individuals, wide food, disease resistance and environmental adaptability, and has adapted to a variety of breeding methods and other good traits; its resistance to low oxygen, low water surface, easy feeding management, is a suitable for artificial breeding Aquatic species. If the water temperature is suitable, fish rearing ponds can be raised for more than 100 grams for 40 days or more. After 70-80 days of feeding, the body weight can reach 500 grams or so, and the maximum weight can reach 1500 grams. If the feed is sufficient, the fry can be reared for one year. It grows to 3500 grams.
First, the biological characteristics 1. Morphological characteristics Egyptian beard Aphids in the taxonomy, 鲇 鲇 鲇. The body has a round barrel shape with a flat head, a slightly lower mouth, and a small eye. There are many bony particles protruding from the head and back, arranged in a radial pattern, and the tentacles are developed. There are four pairs of whiskers. The body surface is mucus-rich and has no scales. The back of the body is dark in color and is gray-brown. There are irregular black spots and gray patches on the body side, and the abdomen is white. The back, tail and anal fins are surrounded by red bands. Juveniles are very similar to cockroaches.
2. Living habits Egyptian beard is a benthic fish, mild temperament, fear of glare, like to live in the dark. Apart from swallowing air and ingesting food on the surface, it rarely moves to the surface. When you are full of food during the day, you like to sink in the pool bottom, in the cave or in the dark. Nocturnal activity, frequent feeding, and sometimes hunting in groups to the surface to hunt for food.
Bearded beaks have a good ability to adapt to the environment and can live in various bodies of water. Because there is a breathing aid on the iliac crest, you can breathe air directly out of the water. If you keep your body surface moist, you will not die if you leave the water for a long time. Therefore, the beard owl can live in a low oxygen or shallow water environment where ordinary fish cannot survive. Egyptian beard crickets are more resistant to disease and generally non-lethal wounds are able to heal themselves.
Egyptian beard is a tropical fish, cold tolerance is poor, growth temperature is 18 °C ~ 34 °C, the optimum temperature for growth is 20 °C ~ 30 °C. When the water temperature drops to 8 °C ~ 10 °C, it will cause frostbite, watery mildew, when it falls below 7 °C, it will begin to die. Therefore, during the artificial wintering period, the water temperature of Egyptian beard must be kept at least 13°C. When the water temperature rises above 15°C, normal feeding is started, and the temperature is high at 20°C~35°C. In general, 5 to 9 months are the peak of feeding, and the fastest growth rate is at this time.
3. Edible Egyptian beard ape is an omnivorous fish dominated by animal foods, its food intake is large, the amount of daily eclipse is 5%~8% of its own body weight, and the maximum amount of daily eclipse can reach more than 15% of body weight. In natural waters, fish fry mainly feed on rotifers, leeches, etc. In the adult stage, they mainly eat small fish, shrimp, aquatic insects, benthic animals, dead animal carcasses, organic debris, phytoplankton, and aquatic plants. . Under artificial breeding conditions, wild fish, shrimps, leeches, aquatic insects, fish meal, cocoon, fly maggots, snail meat, slaughterhouse scraps, etc. can be fed, as well as vegetable feeds such as peanut cakes. Bean cake, rapeseed cake, rice bran, wheat bran and duckweed. Of course, it would be better if you can feed compound feeds.
It is worth noting that the Egyptian beard gluttonous, such as overfeeding, will produce excessive ingestion and bulge; at the same time, it also has a strong ability to fight hunger. During the artificial wintering of fingerlings or broodstock, 4 to 5 No feeding or death in months. Therefore, artificial feeding requires regular quantitative feeding, when it is not enough to be full of hunger, affecting growth.
Second, the construction of farms generally requires the construction of seedling pools, adult fish ponds, and wintering ponds. It is also possible to build a hatchery pool. When designing, it is best to consider one pool for multiple use, either as a wintering pool or as a spawning, hatching, and fry cultivation pond.
The pond area is generally based on the scale of farming. Seed pool area is usually 5.0 ~ 10.0 meters 1.0 ~ 2.0 meters, pool depth 50 ~ 60 cm, depth 30 ~ 40 cm. Generally, the pool is about 20 cm above the ground level to prevent rainwater from entering the pool during the rainy season. Adult fish pond area is generally 8.0 ~ 20.0 meters 2.0 ~ 3.0 meters, pool depth 80 ~ 120 cm, depth 60 ~ 80 cm, the pool is about 40 cm above ground level is appropriate. The wintering pool area is generally 10 to 50 square meters, and the pool depth is 1.5 to 2 meters. The wintering pool requirement cannot be less than two ports. In order to facilitate clearing the pool completely, it also requires a heat source and separate intake and drainage equipment.
Third, bred broodstock breeding 1. broodstock collection and collection of broodstock is best carried out in the fall. Before the collection, a nearby beard breeding farm should be surveyed to understand the source, age, weight, and feeding status of the fish. To choose a healthy physique, bright body, full body, normal activities, disease-free without injury as a broodstock. It is better to collect the kinship of female and male broodstock; the broodstock's age requirement is 10 to 12 months old and the body weight is 0.5 to 1 kg. The ratio of hens to males collected is 1:1 or 1:1.2.
