Razor Clam Mariculturists

            Mudflats and mariculture island, Zhangjiang Estuary. At left, note walking channels where razor clams are planted on the mudflats. Also note the ciruclar clones of invasive Spartina alterniflora. At right is one edge of the artificial island, constructed to control the tide, exclude predators, and aid mariculture. The island also excludes Spartina seed, which is an unexpected bonus.

Mangrove seedlings planted around island. Mature mangroves will protect the island in typhoons.


Women cultivating razor clams inside levies of the mariculture island. Note flashlights on their hats. This is work with long hours.

Clam cultivating channels outside island. Note encroaching S. alterniflora.


Woman harvesting immature razor clams on mudflats outside island. Note S. alterniflora and tragedy of the commons bearing down on these people.

                                            Spartina alterniflora, Zhangjiang Estuary.

The following show mariculturists working on the mudflats at low tide


            Note mangrove and Spartina seedlings, which interfere with their activities.


Note the razor clam harvesters among the invading S. alterniflora.  A tragedy of the commons. To remove Spartina costs time needed to be spent cultivating clams.
