Qinghai is known as the "Water Tower of China", which has abundant and sufficient cold water resources. The reservoirs of many large and medium-sized hydropower stations in the province between Longyangxia and Jishixia, the main stream of the Yellow River, are considered as one of the best areas for cage culture of salmon because of their clean water bodies and excellent water quality, with the water temperature ranging from 2 degrees Celsius to 22 degrees Celsius all the year round.
It is understood that in 20021year, there were 27 farmers (enterprises) breeding salmon and trout along the yellow net box in the province, and the cage culture area reached 32.6 hectares. The high-quality and pollution-free cold-water fish produced in Qinghai, represented by salmon, rainbow trout and golden trout, sold well outside the province, and exported 1600 tons of salmon to Russia last year.
Development History of Salmon Culture in Qinghai Province
With its unique resource advantages, Qinghai Province has learned from and introduced Norwegian complete sets of cold-water fish cage culture equipment technology and eco-friendly culture equipment since 2007, introduced fish species from the United States, Norway and Denmark, mainly promoted salmon and trout species, and promoted deep-water large-scale cage culture technology, which covered the large water surface along the Yellow River reservoir and started the land-based fishery demonstration pilot work.
During the period, it has successively broken through key technologies such as artificial propagation of salmon and trout, fry cultivation, artificial bait feeding, large-scale breeding, and fish disease prevention, and obtained 8 scientific and technological achievements in basic fishery research and aquaculture technology demonstration and promotion, and 2 provincial and ministerial-level scientific and technological progress awards. The scale of cold-water fish breeding in the province has also been continuously expanded, which has also added more economic value and vitality to the clear Yellow River basin.
