Treatment Protocol for Molting Failure and Abnormal Body Color in Whiteleg Shrimp

2026-06-05

During the first and fifteenth days of the lunar month, whiteleg shrimp enter their molting phase and require substantial amounts of trace elements such as calcium and magnesium. In some ponds, instances of incomplete molting or soft shells after shedding—along with weakened health, dull body coloration, and a rust‑colored hue—are all attributable to trace element deficiencies. Therefore, farmers are advised to supplement trace elements on a regular basis to ensure smooth molting and help the shrimp regain their vigor.

Recommended formulation: Quick‑Acting Multi‑Mineral Supplement + Stress‑Relief Detoxifier

Before use, white shrimp often exhibit rust-colored discoloration, pale muscle tissue, reduced activity, and soft shells—symptoms that typically occur during the major molting periods around the first and fifteenth days of the lunar month. Subsequently, apply a combined treatment of Sùbǔ Duōkuàng (3 mu per bag) and Yìngjī Jiědúlíng (2 mu per bag), evenly dispersing the mixture across the entire pond in the evening; noticeable improvements are seen by the next day. The shrimp’s body color becomes bright and translucent, their overall condition recovers, and feeding resumes more rapidly.

Suitable for use during inclement weather such as overcast and rainy conditions, it effectively helps alleviate stress and boost immunity. It is recommended to administer once every 7 days or so.
