Water management in Pacific white shrimp aquaculture

A reported two-season deployment in coastal Shandong, China, covering 1,074 mu (approximately 71.6 hectares).

Setting

The supplier’s revised project brief describes recurrent Vibrio outbreaks, poor water quality and heavy antibiotic use before deployment. The programme ran in 2017–2018 across pond, greenhouse and industrialised culture systems.

Equipment

The brief records five N-600 on-site chlorine dioxide generators. It reports treatment every 10–15 days at 0.3–0.5 ppm. These are historical operating conditions reported for this project, not a treatment prescription for other farms.

Reported outcomes

The brief reports survival improvements of 28% in ponds, 36% in small greenhouse systems and 13% in industrialised systems, water reuse above 90%, and no prohibited veterinary substances detected in the sampled shrimp. Sample sizes and whether the survival changes are relative percentages or percentage-point increases are not specified in the brief.

Interpretation

These are project-reported outcomes. The brief alone does not establish causation, the absence of future outbreaks, or performance in a closed recirculating aquaculture system.

Photographs & supporting material

Supplier photographs from the N-600 aquaculture collection. Individual dates and sites are not specified. Culture-plate photographs are illustrative source material; they do not independently establish treatment efficacy.
