C Mandarin fish is more expensive. In the Yimutian website, I learned that the price of Mandarin fish is 77.32 yuan a catty and the price of perch is 33.3 yuan a catty, so Mandarin fish is more expensive. Mandarin fish often feed on live fish and shrimp, the breeding cost is high, due to bait fish, Mandarin fish disease led to its decline in numbers to Mandarin fish prices are getting higher and higher.
