1. Long growth cycle: Generally speaking, shrimp has a short growth cycle, while flower shrimp has a long growth cycle of up to one year, so the production is relatively small.

2. High environmental requirements for aquaculture: flower shrimp need to live in salinity, water temperature, water quality and other environmental factors, and the stability and quality of these factors require high inputs.

3. High market demand: flower shrimp is loved by consumers for its delicious taste and rich nutritional value, resulting in an oversupply in the market and a corresponding rise in price.

4. High processing costs: in order to maintain the original flavor and texture of flower shrimp, the need to use special processing methods, such as steaming, boiling, deep-frying, etc., the processing cost is higher.

Combined with the above factors, the price of flower shrimp is relatively high. However, the specific price level will be affected by a variety of factors such as region, season, brand.
