Coming to the border commune Phuoc Chi, Trang Bang town, Tay Ninh province, when asked about the Ca cuong farm of Ms. Nguyen Thi Lan, almost everyone here knows, because Mrs. Lan was the first to give her child. Ca cuong has returned to the locality to propagate and apply many technical and high-tech processes to cultivating and deep-processing products from Ca cuong.
The process of raising Ca cuong according to the Aquaponist model of Ms. Nguyen Thi Lan brings high economic efficiency. Sharing about her start-up journey from the Ca cuong farming model, Ms. Nguyen Thi Lan said that Phuoc Chi commune is considered a pure agricultural commune, so people here mainly grow rice and since childhood she has been attached to it. with fields, garden vegetables, frogs, frogs…; in it, there is a Ca cuong However, due to the changing habitat, the wild Ca cuong is gradually disappearing in the wild. In 2015, through researching on the information pages, she learned that Tay Ninh has successfully propagated Ca cuong in captivity, so she came to buy seed for trial at home. Through many times of raising and propagating Ca cuong failed because she did not know well about Ca cuong species, but with determination, not discouraged, she finally understood the technical process of raising Ca cuong. At the end of 2016, she has invested in 10 ponds with 2,000 breeders. In 2017, she started selling the first batch of Ca cuong and was popular with consumers. The benefits brought back far exceeded the plan with the average price of 30,000 – 130,000 VND / commercial Ca cuong and 100,000-200,000 VND / Ca cuong seed. According to Lan, Ca cuong is a fast-reproducing species with large numbers and lays all year round. Each birth is only 1 – 1.5 months apart / litter. Each nest of Ca cuong has about 100 eggs, after 5-7 days the eggs hatch into larvae, the hatching rate is nearly 100%. From hatching to commercial sale about 45 days, while raising for spawning about 75 days. Currently, Ms. Lan’s Ca cuong farm has an area of 3,000 m2. Raising Ca cuong is not difficult, but multiplying Ca cuong herds is not easy because Ca cuong is very sensitive to the environment, especially pesticides, in order to raise Ca cuong, it is necessary to choose a cool place, the water source is not polluted. . Therefore, farmers need to continuously monitor the growth and reproduction of Ca cuong to adjust appropriate care to achieve the best results. However, according to Lan, the food for Ca cuong is fresh food such as fish, baby frogs, and baby frogs, so when the food is not consumed, it is easy to pollute the water source. To ensure that the water source for raising Ca cuong is clean enough, farmers must change the water regularly. In addition, the process of growth from hatching to maturity, they undergo 5 molting, each time the farmer has to follow up to remove the embryo, so it takes a lot of time. 
The process of raising Ca cuong according to the Aquaponist model of Ms. Nguyen Thi Lan brings high economic efficiency. In early 2020, by learning about the aquaponist model (a combination of aquaculture and hydroponics grown hydroponics), she realized that this model was suitable for her Ca cuong farm. Investing in building 30 more Ca cuong ponds with a scale of nearly 10,000 fish and stocking dozens of pounds of fish, along with 1,000 m2 of organic vegetable gardens to produce under a closed process. Ms. Lan shared, when applying the aquaponist model, Ca cuong, the food of Ca cuong (which is a fish) and vegetables will be grown in the same circulatory system. Ca cuong eats food and produces waste products in the water. Water containing waste is fed into mechanical and microbiological filtration system. Thanks to the participation of beneficial bacteria, the wastewater from the aquarium will be converted to organic nutrients into vegetable growing tanks, vegetables absorb nutrients in the water, then purify the water and provide backwards. back to the Ca cuong and the spiny fish tanks. As a result of the application of aquaponist technology, Lan’s Ca cuong herd grows healthier, the wastage rate is low, thereby saving 30% of the cost of food for Ca cuong, 50% reduction in the amount of clean water supplied. daily and 70% reduction in labor force. Ms. Lan also said that each month, her Ca cuong farm supplies to the market more than 10,000 commercial Ca cuong, after deducting the cost, bringing in profits from 40 to 50 million VND per month. In addition, thanks to the reduction of input fees, the source of Ca cuong seed sold by Ms. Lan is also 40% lower than the market price. 
The process of raising Ca cuong, growing aquatic vegetables according to the Aquaponist model of Ms. Nguyen Thi Lan brings high economic efficiency. According to Ms. Lan, at present, consumers are mainly aware of products processed from Ca cuong meat such as fried, steamed … because Ca cuong meat and eggs contain many proteins, lipids and vitamins. However, the most valuable of the Ca cuong is the bag of essential oils in the belly of the male Ca cuong. Foreseeing this, in addition to selling Ca cuong seeds, meat, realize that Ca cuong fish sauce is one of the products that still preserves the essential oils of Ca cuong, the delicious and fatty taste is accepted by the market. Lan continues to invest in production lines and fish sauce processing to diversify products from Ca cuong, increase value and have more stable output while more and more businesses and farmers invest. to cultivate this insect. In order to build a brand for the product, capture the One-Commune Program (OCOP), right from the moment the program was launched, she applied for the Ca cuong fish sauce product called “Phong Lan”. . Since registering for the certification of OCOP products, a good reputation, many companies, businesses, and supermarkets have come to find out about the product and more and more orders are placed, Ms. Lan chalk. Khoi said.
