What should be done if Vibrio levels in a whiteleg shrimp pond exceed the permissible limit?

2026-06-05

Recently, many aquaculture farmers in Xiaoshan have been using petri dishes for plate culture and have found that their ponds harbor an excessive abundance of Vibrio bacteria.

Location: Qiantang District, Xiaoshan, Hangzhou

Time: May 18 to May 23

Face-to-face meeting; 8 mu of external pond, water depth: 1.5 meters.

Variety: Whiteleg Shrimp

With recent rising temperatures and unstable weather conditions, feed inputs have been steadily increasing, leading to deteriorating water quality and a rapid surge in Vibrio populations. We recommend using Zhongren’s national‑standard 50% potassium peroxymonosulfate—apply one packet per mu for two consecutive days. (This 50% peroxymonosulfate formulation, in effervescent tablet form, provides three‑dimensional disinfection, effectively cutting off the growth environment of Vibrio from the bottom up.) On the third day, apply “Bacterial Supplement Expert” to replenish beneficial bacteria, which will occupy ecological niches and inhibit Vibrio proliferation.
