The latest breakthrough of Qicai Seed in salmon land-based circulating breeding technology
Plump and smooth, soft and fragrant, rich taste, a mouthful of fascinating, salmon as a high protein, rich in Omega-3 and other polyunsaturated fatty acids of high quality ingredients, more and more popular, consumption heat continues to heat up. At present, the annual consumption of domestic salmon reaches 140,000 tons, and the sales volume is expected to exceed 300,000 tons by 2030.
Salmon (salmon trout, including rainbow trout, atlantic salmon, etc.) is the world's recognized excellent farmed fish. As a typical migratory fish, grown salmon live in the ocean and swim to freshwater to spawn and hatch. In the industry chain of salmon, breeding and adult fish farming are the most critical links. Qingdao Qicai Seed Technology Co., Ltd. has been applying this technology to high-end fish breeding such as murray cod for many years, and has achieved industrialization promotion. The "Qingdao Qicai Seed Technology Co., Ltd. Laixi Park" invested and constructed by Qicai Seed was designed around industrial circulating aquaculture and has the production capacity of large-size salmon fingerlings.
Salmon land-based circulating breeding process
Introduction and treatment of eyed eggs
When the introduced eggs arrive at the breeding center, they need to be soaked in a disinfectant solution and then washed with clean water.
Artificial incubation
The eggs hatched in the circulating breeding system, with the light, water temperature, water flow speed and other accurate control, and timely cleaning up of the dead eggs, hatched egg shells and dead larvae, assisting the larvae out of the shell.
Larval rearing
After breaking the shell, the yolk sac of the newly hatched larvae has not disappeared, and the nutrient supply is sufficient, so there is no need to feed the fish, and the suitable growth environment for the larvae can be provided by regulating the water temperature and dissolved oxygen.
The cultivation of fry and large size fingerlings After the fry are raised, they are transferred to the breeding system, fed with the self-developed artificial compound feed for the opening of salmon larvae, and timely adjust the artificial compound feed particle size and feeding amount according to the size of the fry, while paying attention to monitoring various water quality indicators and preventing various diseases until the cultivation of large-size fingerlings is completed. All the routine of salmon land-based circulating breeding can be prevented and controlled, and the fingerlings produced can reach SPF level, which can prevent the occurrence of diseases from the source, and provide optimal breeding varieties for facility fisheries.
