Fishermen

These are the Vietnamese water puppets, a pair of fishermen in a boat.  We saw a lot of people fishing for a living or to supplement their living.
Not only is Vietnam blessed with an abundance of water (and sometimes cursed with flooding), but the water is rich in nutritious animals, even in places that are full of action, like pilgrimage sites, where thousands of visitors come every day.
Mainly people row small boats and fish with modest, traditional equipment.  Without outboard motors, there's less pollution.  Anyway, they don't have to go very far to find fish.

The man wading with a net is retrieving fresh water clams from the river.
The other pictures more or less speak for themselves.  They were taken from boats, because almost every day trip we took involved an excursion in an aluminum, flat-botton, stub-nosed rowboat, usually rowed by a young woman.

 This is a floating fishermen's village in Ha Long Bay, one of those places that's so scenic that you get tired of the beauty.

On one of our water excursions, in Hoi An, we came upon a fisherman casting his net out into the river.  After I took a couple of pictures, he rowed over to our boat and asked for a tip.  He earned it.
