The qing drum gorge is in the middle of the yellow river, where, on average, more than 50 tons of rainbow trout go to the table of domestic and foreign consumers every day. How does this highland canyon produce the hot industry of cold-water fish
Choi jianjun: on a fishing platform at the dragons' rainbow shark farm, a number of workers are gathering around the box to fish. These fish jump up and down, they're big, they weigh about 8 to 10 pounds each。
The rainbow trout caught will be inhaled into a transparent pipe, a vacuum pump developed by the company itself, and a fish will appear to be on the elevator to enter the operating platform gently and gently. This approach, compared to traditional channel fishing, can significantly reduce the amount of lactating acid produced by fish in stress struggles, with maximum assurance of the tenderness of fish. A worker teacher just told reporters that the order contained 13,000 fish to be sent to thailand and malaysia. Since the beginning of the year, there has been a steady flow of corporate orders from which, on average, more than 50 tons of rainbow trout are sent each day to the table of domestic and foreign consumers。
Some viewers may wonder why rainbow trout originating in the ocean can be farmed on a plateau scale. Since the canyons of dragons are at an average altitude of more than 2,600 metres above sea level, the water source is mainly upstream glaciers, snow mountains melt water and is less contaminated by humans. The waters are vast, amounting to 383 square kilometres, with an average depth of 120 metres. Moreover, the average water temperature remained around 12 degrees celsius throughout the year, and these natural conditions, unique in nature, provide the ideal growth environment for cold-water fish such as rainbow trout。
And the answer to rainbow trout from the highlands is hidden in every detail of corporate science. More than 200 round-shaped breeding net boxes are located on the water surface of the entire gorge. The centre of each box is equipped with a feed pipeline. The long-range automatic feeding platform automatically produces each feeding dose based on water temperature, soluble oxygen saturation, etc., and delivers the feed accurately through a single pipe to each breeding net box, allowing fish to eat healthy “nutrient meals”。
In the last two years, with the establishment of a deep-processed production line for dragons and rainbow trout, enterprises have also been able to tailor their products to the different needs of their clients, in the form of whole fish to fish willows, from raw to cooked food, which is very rich. Today, with special support from the cold sea fish industry policy, rainbow trout produced by the gorges account for more than 50 per cent of the national rainbow trout market. It also drives up-to-down industries such as local logistics, packaging, specialty catering and rural tourism, indirectly boosting local employment by over 2,000 people, and truly leaving the “hot industry” in the highlands。
