Shark fin is just such a commodity. Despite the large numbers of sharks being caught today, the price of shark fin continues to rise and there is even a demand for artificial shark fin to fill the gap in the market. Thus in the dry goods shops of Taipei's Tihua Street one can find so-called "vegetarian shark fin."
如今鯊魚捕得雖多，魚翅照漲不誤，市場上還需要人工魚翅填充，賣南北貨的迪化街也出現所謂的素食魚翅。
