The photo (A) shows a general view, probably Van Ninh area where the World Fish Center had a group of research ponds including those used for sea cucumber research. The photo (B) shows some of these ponds under preparation, perhaps for sea cucumber farming trials in combination with babylon snails. The photo shows plastic wall liners, fences and sand etc.
Note: We decided not to watermark the photos in order not to upset its clarity. However, we trust you will notify us if you wish to use a picture or more. This is expected and will be appreciated.
