Nearly 100 families in the central Quang Ngai Province depend on picking don, a kind of mussel, from the Tra Khuc River for a living.
The mussel catcher's tools include a rake weighing more than 10 kg with a 2.5-meter bamboo handle. The rake is attached to a strap to keep the catch. The person holds the bamboo handle with both hands and walks backward to catch mussels.
In recent years, people have been worried about their future prospects since the catch has been gradually declining.
People start working at 3 a.m. and earn around VND200,000 ($8.67) in a day.
