Gayam Snail Harvesters Face Significant Dangers at Sea

Gayam snail harvesters on Pulau Tuba confront the perilous threat of being swept away by strong sea currents while diving to collect their catch. These divers operate without full scuba equipment, necessitating a high degree of skill and caution in challenging marine conditions. The harvesting activity itself is strictly limited, ceasing if water depths exceed four metres, underscoring the inherent risks involved.
Risk of Being Swept Away by Strong Currents

The primary danger faced by gayam snail harvesters is the unpredictable and powerful force of sea currents. These currents pose a constant risk of dislodgement and being carried away from their diving location. To mitigate this, harvesters employ a specific safety measure: they tie a piece of wood to a rope and maintain hold of it at the water's surface. This rudimentary flotation device acts as an anchor, helping them resist being pulled by the currents.
Limited Diving Equipment and Depth Requirements

Harvesters are required to dive to depths of two to three metres to reach the seabed, where the gayam snails are found buried approximately two inches beneath the sediment. Crucially, these dives are conducted without the benefit of full scuba gear, meaning divers rely on their breath-holding capacity and diving skills. The harvesting operation is halted if the water depth increases to four metres, indicating conditions that are too hazardous for their current equipment and methods.
Navigating Challenging Tidal Conditions

The harvesting of gayam snails is closely tied to tidal patterns and sea conditions. Harvesters typically operate five days a week, aligning their efforts with the low-tide schedule. They specifically target "dead water" periods, which are times when the sea currents are naturally weaker, offering a slightly safer window for their dangerous work. Even during these periods, the presence of strong currents remains a significant concern.
