Summary
Fishery worker who harvests natural sponges from the seabed using diving or freediving, and sends them for cleaning and processing.
Description
Sponge harvesters are fishery workers who primarily collect natural sponges inhabiting shallow seas or mid-depth seabeds using freediving or scuba equipment. The harvested sponges have mud and attachments removed on the boat, then undergo washing, drying, and sorting on land before being circulated as craft or beauty materials. Work often begins early in the morning, requiring skills and physical stamina to repeatedly dive safely while assessing currents and sea conditions. Fishery ground management and consideration for resource conservation in line with seasons and regulations are also important.
Future Outlook
Although there is a certain market for natural sponges in medical and craft applications, demand is shrinking due to the proliferation of synthetic sponges and environmental protection regulations. Creating added value through combinations with ecotourism or experiential fishing will be key going forward.
