Sea cucumber at risk due to overfishing

While there is growing conservation momentum for shark, the trade in sea cucumber, another high-value Chinese delicacy, has not diminished. Seven species in this group of animals are now endangered due to overfishing, warns a new report.
Sea cucumber is the second most valuable seafood export from the Pacific Islands after tuna. However, unlike tuna fishing, which requires considerable investment in vessels and gears, sea cucumber harvesting can be done with minimal equipment, such as a bucket. Therefore, sea cucumber harvesting provides an important source of livelihoods for poor and vulnerable communities.
A study from WorldFish scientist Hampus Eriksson and shark trade expert Shelley Clarke from the Australian National Centre for Ocean Resources and Security notes that current regulatory environments are insufficient to safeguard sea cucumbers and recommends strengthened conservation strategies. Proper governance of fisheries and supply chains will be necessary to make sure that sea cucumbers are harvested sustainably and fishers livelihoods are not negatively impacted.
Stephen J Hall, Director General, WorldFish, states, “We must achieve a balance between conservation and the livelihoods of those that depend on this valuable resource. Improved trade monitoring systems will greatly assist in guiding appropriate management responses. In parallel we should also put greater effort into understanding the potential of aquaculture to reduce the pressure on wild caught sea cucumber.”
Scientists note that sea cucumber plays a vital role in the recycling of nutrients that can, in turn, feed algae and coral. Some believe that they may also play a role in reducing coral damage due to ocean acidification.
Part of the challenge is better understanding how global supply chains can be governed in ways that support equitable distribution of benefits to fishers and under what management models this can be achieved.
The report, entitled Chinese market responses to overexploitation of sharks and sea cucumbers, also discusses how the Chinese seafood market for these products has adapted to compensate for declining wild catch stocks. For sea cucumbers, aquaculture is now a major contributor towards maintaining overall production in the face of overfished wild resources. A Chinese government led campaign against consumption of shark fin soup combined with mounting global concern has reduced trade, the report concludes.
