South Korea: Full-scale promotion of sea urchin culture test using cabbage leaves

Tridge summary

Researchers on Jeju Island have found that sea urchins without gonads (eggs) can thrive in tidal green fishing grounds, where seaweed does not grow. The Jeju Research Institute of Oceans and Fisheries discovered that feeding sea urchins cabbage for three to four months can improve the development of gonadal and taste components, resulting in a sweeter taste and higher gonad formation compared to other food sources. This could provide a profitable opportunity for farmers and generate income for fishing villages through sea urchin farming. The institute has installed cage-type aquaculture facilities to demonstrate this method, with expectations of both short-term profits and long-term branding strategies, leading to job creation in the fishing industry.

The only sea urchins in the tidal green fishing grounds where seaweed does not grow are those without gonads (eggs), in other words, 'unskinned sea urchins'. In Jeju Island, gaet green fishing grounds account for 33% of the total. Representative places of Gaetnokgeom Fishing Ground are Gonae-ri, Aewol-eup, Haengwon-ri, Gujwa-eup, and Wimi Fishing Ground. The Jeju Research Institute of Oceans and Fisheries announced on the 7th that the result of an empirical test using cabbage leaves on sea urchins, which inhabits the green sea area and whose commercial value is low, showed that the sea urchins were full of eggs. In order to search for a suitable food source for sea urchin farming last year, the Jeju Research Institute of Oceans and Fisheries, prior to this aquaculture demonstration test, fed cabbage, black locust serrata, and scallops, which are easily obtainable agricultural and fishery products, for 3 to 4 months to improve the development of gonadal and taste components. color ...
