The article highlights the high demand for queen tiger prawns, also known as sea tiger prawns, in the seafood market as the year ends, particularly in Ho Chi Minh City and famous coastal areas like Nha Trang, Quy Nhon, and Phu Quoc. The price of these prawns has significantly increased due to their rarity and superior meat quality, with each kilo costing 1.3-1.7 million VND, making them the most expensive domestic seafood this year. The high price is attributed to the strict fishing conditions, long growth period, and the challenges in catching them, especially in adverse weather conditions. The article also mentions that queen tiger prawns are valued for their firm, sweet meat, which is as good as lobster but with a thinner shell.
