TPO - Farmers in Ca Mau only need to use incense sticks to count thousands of tiny baby crabs in a short time to deliver to customers.

Ca Mau has hundreds of thousands of hectares of aquaculture area, concentrated in the districts: Ngoc Hien, Nam Can, Cai Nuoc, Dam Doi, Thoi Binh...

Mr. Nguyen Van Hien's family (45 years old, residing in Cai Nuoc town, Cai Nuoc district, Ca Mau province) has been involved in the business of selling crab and shrimp seeds to local aquaculture farmers for more than 10 years.

Most of the baby sea crabs sold are only the size of peppercorns or melon seeds, so Mr. Hien and his wife used incense sticks as a tool to count the crabs they sell to customers.

Each turn, the seller counts 5 crabs in front of the buyer until the number given by the customer is reached.

Because of his many years of experience in the profession, Mr. Hien only needs about 6 minutes to count 1,000 crabs for customers.

The shrimp seeds are only as small as a needle, so Mr. Hien and his colleagues sell them by estimate.

The seller and buyer look at the density of shrimp in the bowl to agree on an estimate of 1,000 shrimp/bowl.

After counting, the shrimp will be put into plastic bags, pumped with oxygen, tied with rubber bands and delivered to customers.

Mr. Hien's facility supplies the market with an average of 450,000 shrimp seeds and tens of thousands of crab seeds of various kinds every day.

After buying shrimp and crab seeds, people will bring them to the pond to raise.
