In Hanoi, online markets are offering cotton lobster tails at surprisingly low prices, as little as 350,000 VND/kg, which is equivalent to the price of black tiger shrimp. This has led to a surge in demand from housewives. The cheap prices are attributed to hot weather conditions affecting lobster farms, leading to mass suffocation and farms selling the frozen lobsters at discounted rates. Despite the lower quality compared to live lobsters, the cheap price makes it a popular choice for consumers.
