Ningxia Jingcheng Aquaculture Base

Ningxia Jingcheng Aquaculture Base

Ningxia Jingcheng Aquaculture Base is located in Lanfeng Village, Ligang Town, Helan County, Yinchuan City, Ningxia Hui Autonomous Region. It is a benchmark enterprise for saline‑alkali land aquaculture in Northwest China. The base was established in September 2009 and covers a total area of 600 mu (approximately 40 hectares), including 360 mu (24 hectares) of intensive ponds, 7,500 square meters of factory‑based workshops, a 240‑mu (16‑hectare) integrated rice‑fish farming zone, and a comprehensive information service center. Together, these form a modern fishery demonstration system integrating "seedling breeding, grow‑out farming, ecological cultivation, and technology research and development."

I. Core Technologies and Species Innovation

Guided by the development philosophy of "technology‑driven, ecological recycling," the base has established long‑term collaborations with research institutions such as Shanghai Ocean University and Ningbo University, overcoming several technical challenges:

Breakthrough in Saline‑Alkali Water Aquaculture Technology: Through a combination of chemical alkalinity reduction, physical alkalinity stabilization, and biological alkalinity control, the pH of the water is consistently maintained below 9.0. This has enabled the successful land‑based culture of marine species such as Pacific white shrimp and California bass, filling a technological gap in Northwest China.

Factory‑Based Recirculating Aquaculture System (RAS): The base has built closed‑loop RAS workshops that achieve 24‑hour water quality monitoring, tailwater purification, and water recycling. The yield per unit water volume is more than 10 times higher than that of traditional earthen ponds, with a water saving rate of 90%.

Species Introduction and Development: The base has introduced over 10 premium species, including tench, channel catfish, sturgeon, and mandarin fish. It produces 50 million fry and 400,000 kg (800,000 jin) of marketable fish annually. The yield of California bass exceeds 1,500 kg per mu (approx. 0.067 hectares), and the grow‑out cycle of mandarin fish has been shortened to six months.

II. Industrial Model and Economic Benefits

The base has innovated a linkage mechanism of "base + farmers + market," creating a diversified industrial structure:

Integrated Rice‑Fish Farming: On 240 mu (16 hectares) of paddy fields, the base practices "rice‑shrimp coculture" and "rice‑crab polyculture," achieving "double income from a single field." Due to its superior ecological quality, the crab‑rice commands a market premium of 30%. The yield of Pacific white shrimp reaches 150 kg per mu, with an average profit of 7,000 RMB per mu.

Contract Farming and Brand Building: The base has established long‑term partnerships with supermarkets and catering enterprises in Yinchuan and surrounding areas. Its products include California bass, Pacific white shrimp, and paddy‑field crab, with annual sales reaching 17 million RMB. In 2023, the base was recognized as a "National High‑Tech Enterprise," becoming a standardized demonstration window for aquaculture in Northwest China.

Ecological and Social Benefits: Through the "workshop – pond – paddy field" tailwater recycling model, the base reduces tailwater discharge by 150,000 cubic meters annually. It has driven more than 400 surrounding farm households to engage in aquaculture, with each household increasing its annual income by over 100,000 RMB on average.
