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.
