重庆市万州区水产研究所大周基地是“长江上游珍稀特有鱼类国家级自然保护区重庆增殖放流站”的野化驯养基地，现设有网箱32个，面积约800平方米，目前有长江鲟、胭脂鱼、岩原鲤等珍稀特有鱼类和经济鱼类20余种，长江珍稀名优鱼类苗种年生产能力达2000万尾以上。

The Dazhou base of the fisheries research institute of Wanzhou District serves as a wild acclimation center for the rare fish species in the upper reaches of the Yangtze River. Equipped with 32 net cages covering an area of approximately 800 square meters, the base conserves over 20 rare and commercial fish species. Its annual output of rare and high-quality fish fry exceeds 20 million.

近年来，该基地对投放到天然水域的鱼苗不断强化短期野化适应性训练，并加强长江鱼类种质资源保存及驯养工作，有效推动了长江水生物种多样性保护。

In recent years, the base has continuously strengthened the short-term wild acclimation training of fish fry before their release into natural waters, effectively helping boost the wild populations of the rare species.
