1. Rare: Water-colored lantern fish are rare fish, and their number in nature is very limited. This has led to a shortage of supply, which has led to an increase in prices.
2. Wild fishing: most water fish are obtained through wild fishing, not farming. There are various uncertain factors such as weather and ecological environment in wild fishing, and the yield is unstable, which increases the fishing cost and the price.
3. Characteristics of fish: Shuilingdengyu is a delicious fish with rich nutritional value. At the same time, their shapes are also unique, and people especially like them because of their bright spots. Therefore, high-quality water-filled lamp fish is more scarce and the price is correspondingly higher.
4. Transportation and fresh-keeping costs: As water lily bulbs belong to marine fish, they need to be refrigerated and transported quickly after fishing to keep the fish fresh. Refrigeration and transportation costs are also one of the reasons for the price increase.
To sum up, the price of water lily is high because of its scarcity, wild fishing, high edible value and corresponding transportation and preservation costs.
