Sea urchin gonads are highly prized in some Asian and European seafood markets where demand has been increasing. [5] In the New Zealand market, the roe can reach NZ$70 per kg. [ 18 ] However, because E. chloroticus is not well known in Japan and has a reputation for having a bitter taste, this sea urchin is unable to reach a high price in ...
