Since around 2004, Mr. Man has been raising shrimp in super-intensive farming, initially in earthen ponds, then upgraded to tarpaulin ponds, and now he continues to learn and research the method of farming shrimp in a circular manner without waste discharge. With 2 ponds and 1 settling pond on a total area of ​​6,000 m2, he annually harvests 15-20 tons of commercial shrimp, excluding expenses, even in unsatisfactory crops, he earns a profit of 1.5-1.7 billion VND.

Mr. Man also raises 2 super-intensive shrimp ponds with no discharge, each year harvesting 15-20 tons of commercial shrimp.

In addition, Mr. Man also pioneered the implementation of an environmentally friendly model of raising crabs in plastic boxes with circulating water filtration. Mr. Man said: "In February 2004, I invested over 400 million VND in 1,000 plastic boxes to raise soft-shell crabs to become firm crabs in a circulating water filtration system. This is a method I learned from the Internet and visited in and outside the province. In April 2004, the Department of Science and Technology supported me in implementing the project of raising crabs in plastic boxes in a circulating water filtration system, supporting the implementation of the project with 600 plastic boxes and providing technical guidance. In the first crop, I raised 600 female crabs with weak shells, raised them for 35 days to become full-shell crabs, reaching 540/600 crabs, deducting expenses, the profit was about 60 million VND. From the techniques and experience in raising, I have applied this model since then".

Crabs are raised in plastic boxes.

Every day, Mr. Man buys crabs, both selling meat and selecting soft crabs and crabs with weak roe to raise in plastic boxes to make firm crabs and full of roe.

According to Mr. Man, each batch of crabs is usually only about 35 days before being sold. It is very easy to take care of. The crabs are fed a piece of fish every morning and afternoon through an automatic filtration system that helps keep the water in the crab boxes very clean. This model is easy to manage, care for, and effective. "To have a large amount of crabs, I also do the job of purchasing square crabs, weak crabs, and healthy shell crabs, then put them in the boxes. When the market has demand, I also raise 2-shell crabs (soft shell crabs)... Income is about 300-500 million VND/year," he shared.

Thus, with the super-intensive shrimp farming, crab breeding in plastic boxes, buying square crabs to sell for meat, and producing more than 1 hectare of improved extensive shrimp farming, Mr. Man's family achieves a total income of 1.5-2 billion VND/year.
