Having cherished many years before, however, by the end of July 7, Mr. Tran Xuan Giang, Hoang Tan commune (Quang Yen town (Quang Ninh)) boldly invested more than 2023 million VND to invest in crab farming model in Vietnam. This is the first model of crab farming in plastic boxes in Quang Yen town, which promises to open a promising direction for the local aquaculture.

3 years ago, after being introduced and shared by a close friend about the model of raising crabs in plastic boxes, seeing that there were many prospects, Mr. . From 2020 until now, Mr. Giang has researched on many information channels and went to the models of crab farming in boxes to learn from experience. Before that, his family also had experience in raising crabs in the form of extensive farming in the lagoon for more than ten years. Although this model gives a good income, crab farming in the lagoon is prone to many risks, crabs often get sick, leading to low yield, low economic value, and low profit. After a period of research, Mr. Giang realized that the model of raising crabs in plastic boxes in some other localities brought high economic efficiency, so he decided to invest in factories, plastic box systems, water treatment systems, animals. like… follow this model.
Taking us to visit directly the model of crab farming in plastic boxes, Mr. Tran Xuan Giang shared: Initially, the family reinvested in the factory system, ordering 648 plastic boxes to raise crabs. Each rectangular plastic box has a length of 30-40cm, divided into compartments, each holding a crab. To tame the crabs that naturally grow and develop in a plastic box environment, it takes a lot of time and effort. Crab varieties raised in boxes are selected and purchased from local extensive crab farmers. Each baby weighs about 2-2,5g, ensuring good health. The water source for farming box crabs, which Mr. Giang takes directly from the Ben Giang River, has a salinity corresponding to the lagoon crab variety that people are raising in the form of extensive farming. During the rearing process, it is necessary to regularly check the water quality parameters, temperature and the health and eating ability of the crabs, in order to promptly adjust the system to ensure the habitat for the crabs.
According to Mr. Giang, raising sea crabs in boxes has many differences compared to raising crabs in the lagoon. Raising crabs in plastic containers takes up less space. However, the process of feeding crabs will take longer than that of crabs raised in the lagoon because they will have to drop food into each feeding box. Every day, crabs are cared for a diet of 2 meals according to the correct time frame (7 hours and 17 hours). It is quite special that the food of crabs is mainly fresh seafood such as oysters, fresh fish, mussels... These are all food sources collected from local waters, so it is easy to be proactive and save costs. Not only that, rearing sea crabs in plastic boxes can control the quantity, reduce disease, easy to care for, and quickly harvest...
After more than 10 days of stocking over 600 crabs in plastic boxes, so far the crab farming model of Mr. Tran Xuan Giang's family is adapting and growing well. Survival rate is 93-95%. It is expected that crabs reared in boxes are from 15-35 days to the molting (molting) day cycle. This is the stage when crabs start to harvest, reaching about 3-4 fish/kg. Peeled crab has a high nutrient content, so it is ordered by many traders and restaurants. Currently, the average selling price of peeled crabs ranges from 650.000 to 700.000 VND/kg (higher than that of commercial farmed crabs raised in lagoons from 200.000 to 250.000 VND/kg). It is planned that in the near future, Mr. Giang will expand and grow 3.000 crabs in plastic boxes.
Mr. Dam Chi Thiet, Secretary of the Party Committee of Hoang Tan Commune (Quang Yen Town) assessed: Although the model of raising sea crabs in plastic boxes of Mr. Tran Xuan Giang's family is in the pilot stage of farming, it has attracted a lot of attention. interest of many farmers to visit and learn from experience. Currently, Hoang Tan commune encourages households raising oysters, ha, fish in cages, etc. to switch to developing new models, applying high technology to production. In the coming time, if the model of raising sea crabs in plastic boxes continues to be implemented with high efficiency, the commune will create favorable conditions for people to come to learn from experience, apply and replicate this model, towards building a business. Hoang Tan crab brand becomes a local OCOP product.
