Recirculating aquaculture · Nansha, China

Recirculating aquaculture, practiced in the Greater Bay Area.

PanPan Aqua is the public site of Guangzhou Nansha Zhihui Agricultural Technology Co., Ltd. The work centers on a visitable recirculating aquaculture workshop in Nansha, a fishery management platform, and Qiuhao AI microscopes for aquatic-health detection.

A note on scale

Bay Area Agri Valley is described in a Guangzhou environmental impact approval (Yue Nan Shenpi EIA [2026] No. 10, 2 February 2026) as intelligent fish-culture experiments and observational research, with a designed annual experimental culture volume of about 100,000 jin — roughly 50 tonnes. The project’s published total investment of about RMB 853 million should not be read as the capacity of a large commercial fish factory.

What you will find here

Three parts of the work, plainly stated.

A demonstration workshop

A Phase 1 aquaponics intelligent-factory workshop is already in operation in Nansha. Visitors can see recirculating culture practice, water-quality work, and pond-relay farming in its local setting.

RAS operations and the base

A fishery management platform

The company has described a self-developed platform that brings together water-quality monitoring, production logs, equipment control, alerts, and data analysis.

Platform and products

How we describe the company

An operator of RAS practice in Nansha — not a global turnkey contractor.

Public descriptions of the business include factory RAS operations, pond-relay aquaculture, and the development and operation of a modern agricultural park, including Bay Area Agri Valley. We keep to that record.

This site does not claim overseas delivery contracts, a worldwide engineering service network, or a large commercial land-based salmon factory, because those claims are not supported by the public record used to build these pages.
