Food of field crabs must be fresh, not stale, moldy. Need to feed the field crabs enough, if the crabs lack food, it is easy to eat each other. Ms. Nguyen Thi Huong, Yen Tho commune, Dong Trieu district, Quang Ninh province harvests field crabs from her family’s farm. In ponds and fields, it is necessary to arrange a number of eating floors to assess the crab’s catching status, and at the same time to adjust the amount of food according to weather conditions. In the last months of the crab farming cycle, it is necessary to add more animal food in the diet to make the crabs grow fast and firm. It is possible to add more field tilapia and tilapia to eat crab leftovers, reducing water pollution. Field crab is the type that adapts to cool weather, so it is necessary to alternately plant water spinach, rice, and cash crops to keep the crabs’ shade in the summer. The water environment also needs to be kept clean and regularly change the source of water in and out to stimulate crabs to molt and catch strong prey. “Investment capital for crab farming is very low, mainly hiring workers to dig ponds, buy corrugated iron and bamboo poles to enclose the embankment. Currently, every day, my family earns about 3-4kg, selling 150,000 VND/kg ‘, Ms. Huong revealed. Through research, seeing that field crabs are popular with many people, taking advantage of low-lying rice fields for low productivity, Ms. Nguyen Thi Huong studied and brought back field crabs to release on her field. Because field crabs have no place to produce seed, they have to buy from people who go wild. Ms. Huong said: “At first, I bought crab seed from traders from Hai Duong to release, but each release the number of dead crabs was up to 70%. After a few dead crabs, I learned from experience that if I want to have a high survival rate and grow up quickly, I have to buy native breeds…” “In addition to raising commercial crabs, I also zoned the field and selected some adult crabs to breed separately. Here I will invest in buying brick holes to build banks, planting many layers of concrete pillars, with The purpose is to let the crabs live in, creating a favorable environment for the crabs to grow and develop better”, Ms. Huong added. Talking to us, Ms. Nguyen Thi Huong, Chairwoman of the Farmers’ Association of Yen Tho Commune (Dong Trieu Town, Quang Ninh Province) said: “Ms. Nguyen Thi Huong’s model of field crab farming has brought high economic efficiency. . From the initial results, in the coming time, the Commune Farmers’ Union will direct the grassroots branches, exchange experiences, and mobilize people in the commune to replicate this model. Especially, taking advantage of low-lying areas and inefficient rice-growing areas to develop commercial crab farming models, contributing to increasing income and improving the lives of members and people.
