The Jinan Modern Fishery Demonstration Park in Changqing district is emerging as a national model for modern inland fishery, combining advanced technology with green development practices.

Covering more than 50 mu (3.33 hectares) with a total investment of 51.29 million yuan ($7.5 million), the park has built an integrated platform for research, production, and demonstration.

The facility includes over 12,000 square meters of breeding workshops, a 2,200-sq-m technology support center, and 33 high-density recirculating aquaculture tanks. Its indoor farming area covers 5,000 sq m, complemented by 8,000 sq m of outdoor ponds.

Smart management lies at the heart of the park's operations. Supported by the Internet of Things and big data systems, the facility monitors water temperature and dissolved oxygen of the 33 aquaculture tanks around the clock. More than 10 advanced technologies – including liquid oxygen enrichment and a four-layer filtration system – enable a water recycling rate of more than 95 percent, reducing the environmental impact.

The park also pioneers a "fishery-solar integration" model in Shandong province, with rooftop photovoltaic panels generating an average of 1,200 kilowatt-hours of electricity each day. The project saves about 53 metric tons of standard coal annually and cuts carbon dioxide emissions by roughly 134 tons.

In addition to its technological innovations, the park plays an important role in supporting biodiversity and aquaculture development. It cultivates more than 10 species of high-value aquatic products, including Yellow River carp and sturgeon, and produces over five million fish seedlings each year.
