Long Van Nghia, 34, was informally called the ‘midwife of crabs and oysters' after his success in breeding them.

In 2006 when Nghia was head of the province's Saline Aquaculture Experimental Centre, the centre started sea crab reproduction.

At first, the process was unsuccessful as it was new for Nghia and his colleagues. The number of animals bred did not meet demand.

After some months of tracking the environment, temperature and mother crabs' habit, success gradually came. By the end of 2006, Nghia set up a farm with 40 breeding tanks and about 2 percent of the small crabs lived, about 40,000-50,000 total. In 2007, Nghia set up 20 more tanks and 4 percent lived.
