Why do people eat sea cucumbers?

Answered by MSC Commercial Manager UK & Ireland, Seth McCurry

Lauded for their medical and health benefits, sea cucumbers have been a delicacy in China since the Ming Dynasty. Bioactive compounds produced by sea cucumbers have been used in traditional Chinese medicine to treat a number of ailments including arthritis and cancer, and there is ongoing research on a number of nutraceutical and pharmaceutical application of these compounds around the world.   

However, the majority of sea cucumber is harvested for human consumption. Like abalone, shark fin, fish maw and bird’s nest soup, sea cucumber is a delicacy that has been a symbol of affluence and luxury, typically reserved for special occasions like weddings, banquets, and Chinese New Year celebrations. They are highly nutritious, being low in both calories and fat but rich in protein and antioxidants.  

Despite this, the sea cucumber is one of the most unassuming and often overlooked of marine species. With no eyes and no brain, it rarely captures the hearts and minds of humans. However, this primitive echinoderm, which is most closely related to the starfish and sea urchin, plays a vital biological role in marine ecosystems by recycling nutrients; helping to ‘clean’ the ocean. 
There is only one sea cucumber fishery in the world, which is certified as sustainable to the MSC Fishery Standard. The Western Australia Sea Cucumber Fishery achieved MSC certification in 2019 and hand-harvest sea cucumbers in remote and pristine waters. Use of this catch method, means the fishery has very few interactions with the ocean floor and none with threatened or endangered species.  
Sustainable management of wild sea cucumber fisheries, such as that demonstrated by the Western Australian Sea Cucumber fishery, is critical to meet the increasing demand for sea cucumber.
