raise a fish worth 350,000 VND per kg Let's find out together How to raise a snake-like fish There was a time when catfish was priced at 500,000 VND per kg It was the highest-value freshwater fish Catfish Catfish is a freshwater fish but has the ability to survive and develop well in the freshwater environment They are widely distributed in Southeast Asia, in the Mekong River Basin, such as Laos, Cambodia, Thailand and Vietnam In Vietnam, catfish appear in many places from north to south but focus a lot in the eastern region of the Kieu Long River and become a specialty every spring here Catfish is dark blue or gray The body has many yellow spots, round or bulging They also do not have a belly and the chest has a small black spot The body of the fish is up to 90 cm long and can weigh up to 1 kg Catfish is considered one of the rare specialties every spring in the West They are often sold in Kieu Long river markets with the highest price, from 400,000 to 500,000 VND per kg River catfish has delicious meat, chewy and fat, so it is very popular Many restaurants and restaurants buy this fish to cook into specialty dishes such as grilled with chili salt, braised with turmeric, fried, attracting tourists Western specialty catfish Catfish is not only popular because it has a delicious aroma but also because of its high nutritional value which is valued as a ginseng under water Dong Yi calls catfish as a fish The fish has a sweet taste, flat, not frozen, has the effect of blood, white blood, cooling, purifying, heat-treating In fact, catfish contains many nutrients with a high amount of protein than chicken Therefore, catfish is the main ingredient in many methods to treat chronic diseases, blood loss, malnutrition, and sweat in children Especially, catfish helps nourish, strengthen health and the ability to nurture men However, river catfish is getting rarer Therefore, in recent years, the people of Kieu Long River have started to produce artificial and successfully breed this fish with high economic value Many people are successful thanks to catfish Mr. Tran Thanh Hung in Chau Thanh District, Hau Giang Province is one of the first people in the country to successfully breed catfish The model of Mr. Hung is to raise catfish in an underground pond and cover it with sand It is raised at a high temperature but Mr. Hung's catfish has a low consumption rate thanks to the oxygen tank and the machine that creates a stream to turn water into frozen water In addition, Mr. Hung also sets up many plastic tubes in the pond so that the catfish has a hiding place and is less competitive in food Mr. Hung's catfish is also trained Therefore, they develop well only after 7-8 months of raising fish reach a weight of 3-4 catfish per kilogram and can sell for 300,000-350,000 VND per kilogram sometimes up to 400,000 VND per kilogram Unlike Mr. Hung, Mr. Ly Van Bon in Can Tho chose to raise catfish on the river Mr. Bon takes catfish from nature and breed it to raise dozens of tons on the Hau River The advantage of this method is that it can raise up to 20,000 catfish on a single pond Every year, Mr. Bon collects billions of VND from this model Catfish is also a type of aquaculture highly rated by Kien Giang province for its potential, development and investment In March 2019, the province approved a project to collect, preserve and preserve the catfish genes in Kien Giang province in order to preserve and increase the quality of catfish to serve as a product It is known that since 2018, the Ministry of Agriculture and Rural Development of Co Gao District, Kien Giang Province has cooperated with Kien Nong to launch the catfish test-raising experiment in Ao Duc Farmers in Ngo Cao District were visited by the production model and the catfish breeding pond in Hau Giang province After that, the test-raising at three breeding points was quite positive Mr. Huynh Van Thua of Vinh Hoa 3 in Vinh Hoa Hung A group of people who participated in the model said that after six months of breeding the fish reached a weight of 150 grams per catfish, developed well and was not exhausted According to Mr. Thua, catfish is an easy-to-raise species just pay attention to some factors that catfish can grow, develop well and have high economic effects Catfish breeding technology in Ao Duc is not difficult Only those who are difficult to understand learn a little bit can succeed right from the start and quickly raise money First, catfish breeding should be raised in a pond with an area of 500 to 1000 square meters cut, remove all the mud then cover with 7-10 kg per 100 square meters dry the bottom of the pond for 2-3 days then pump water into the pond The temperature in Ao Duc should be maintained at 27-32 degrees Celsius pH from 7.5 to 8.5 Due to catfish is a living species at the bottom, it moves little so you need to pay attention to maintain an oxygen content larger than 5mg per liter In addition, in nature, catfish live in ponds, lay eggs in caves, ponds on the shore so when raising in Ao Duc you need to make sure that the trees do not have oil, such as bamboo, bamboo, dry or water pipes then cut 30-50 cm into each pond In the process of raising, you need to regularly change the water so that the water environment is clean and increase the oxygen for the fish After preparing, it is time to release the catfish The breeder needs to choose the catfish from the popular sources is the artificial breeding catfish The catfish has a length of 1.5 cm without being ground The catfish is bought so let it rest for 15 minutes then add salt water 100g salt per 10 liters of water to bathe the catfish for 5-10 minutes then release the catfish slowly into the pond with a depth of 2-5 catfish per square meter Catfish is quite easy to raise and easy to breed with the advantage of not being picky catfish, catfish, shrimp, catfish, crab, snail In breeding, the main food of the fish is a type of fish with a volume of up to 35% Due to this type of catfish should leave the food on the floor 5 cm away from the surface of the water and place near the body of the catfish Daily feed the fish 2 times at about 8 am and 17 pm Fish from 1 to 3 months old eat 5-7% of the body Fish from 4 to 6 months old eat 3-5% of the body Fish from 3 to 5% Fish from 6 months old only need to eat 2-3% of the body In addition to the main food also need to supplement vitamin C and mycelium into the food for fish to increase resistance and effectively use food In addition, for fish to develop well it is best to check the pond every morning observe the operation of the fish and the color of the pond to discover in time the abnormal phenomena of the fish The best conditions for fish to develop are green water banana flower 5mg per liter oxygen pH from 7.5 to 8.5 purity 30-40 cm Dong Thap Raising catfish is like watering selling 350,000 per kg Mr. Le Van Phuc in Long An Commune, Tam Nong District, Dong Thap Province has used the area of ​​the water on the rice field successfully implemented the model of catfish for high income In terms of nutrition, catfish is considered to be like water In October 2016 Mr. Le Van Phuc constructed 2 areas of 2000 square meters on the rice field to release 10,000 catfish At first, he released the same catfish in the pond and gave the fish a high degree of industrial food More than a month of care, he released catfish to raise big fish in 2 areas and continued to use industrial food to increase the amount of food and increase the growth of fish Every day, Mr. Phuc replaces the water he raises once to take care of the catfish At the same time, he mixes vitamins and some minerals into catfish food to improve immune health and help fish grow faster After 9 months of raising Phuc collects catfish products Now, catfish weighs an average of 300-500 grams per catfish Catfish selling is worth 350,000 per kg After deducting investment and care, Phuc has more than 60 million VND To date, Mr. Le Van Phuc has expanded the catfish farm to 4,000 square meters and established a catfish cooperative in An Long Phuc happily shared his experience of catfish farming On average, every 3 kg of food will produce 1 kg of catfish On average, every year, I harvest 3 catfish batches Each batch collects 700-800 kg of catfish The income is from 250 to 300
