Officially known as Cranial Nematode, the sea urchin is a marine species with high nutritional and economic value, but its future is under threat from over-exploitation. Cage farming has been piloted, with 2,000 breeds and seaweed as the main food source.
Sea urchin is a specialty found in Ly Son’s waters, but in recent years, along with the increasing number of tourists coming to visit, it has been over-exploited. Experimental cage farming, though, helps restore numbers in the wild and also helps people improve their livelihoods.
The coastal waters of Ly Son Island were at one time diverse and plentiful, but local aquatic products have now been over-fished. The introduction of different aquaculture models on Ly Son not only helps improve people’s incomes but also eases pressure on natural exploitation, contributing to the restoration of the ecosystem./.
