From a distance, Xiapu’s aquaculture can look like one enormous grid. Closer understanding begins by separating its different systems. Kelp, the long-bladed seaweed often sold in strips or knots, is not the same crop as laver, the thin seaweed used in sheets and soups. Fish cages serve another purpose again.
Fujian’s agricultural register identifies distinct production zones for Xiapu kelp and laver. Some places, including Sansha and Shajiang, participate in more than one part of this coastal economy. The categories matter because a pole, a rope and a floating enclosure do different jobs. A photograph’s repeating shapes are therefore the visible edge of several kinds of farming, each with its own material needs and sequence of work.
