Embodiment 1
[0029] (1) Prepare aquaculture ponds and desalination buckets, for two aquaculture ponds and four 2 m 3 The desalinated water tanks are disinfected, and sand-filtered seawater is injected into one aquaculture pool to adjust the salinity of seawater between 26-32‰; fresh water after the storm is injected into another aquaculture pool to adjust the salinity to 6‰; Inject the fresh water after the storm into the desalination bucket, and adjust the salinity to 22‰, 18‰, 14‰ and 10‰;
[0030] Among them, the breeding pool is a semi-buried smooth surface cement pool, with a depth of 1.8-2m, a water depth of 1m, and a water capacity of 20m. 3 , printed with scale marks, easy to calculate the water injection volume, there is a lighting lamp on the top of the breeding pond, the power of the lighting lamp is 12W, and the layout density is 1 / 10m 2 The surface of the desalination bucket is tempered glass, the color is light blue to dark blue, the bottom is conical, with scale marks print...
[0036] Small yellow croakers raised in seawater with a salinity of 28‰ to 32‰ are acutely transferred to water bodies with a salinity of 0, 2, 4, 6, 12, 18, 24, 29, 30, 36, 42, 46 and 63‰ , the 96-hour survival rates were 0, 0, 65, 87, 95, 98, 98, 100, 98, 95, 57, 5 and 0%, respectively, such as figure 1 .
[0037] It can be seen that the small yellow croaker is a kind of eurysalline adaptable fish, and its suitable salt range is as low as 4‰, and 65% of the individuals can survive and adapt, and the maximum can reach 42‰.
Embodiment 3
[0038] Embodiment 3: 96-hour semi-lethal experiment of small yellow croaker
[0039] Using the GlobalLogitmodel method to calculate the 96-hour semi-lethal rate of small yellow croakers, the minimum salinity of 96-hour semi-lethal for small yellow croakers is 2.45‰, and the maximum salinity is 41.68‰, as figure 2 .

Abstract
A method for cultivating small yellow croakers with artificial seawater salinity desalination of the present invention specifically includes the following steps: (1) Disinfecting two culture ponds and four desalinated water tanks, preparing a culture pond with seawater salinity between 26-32‰ , the freshwater salinity of another breeding pool is 6‰, and the salinity of the four desalinated water tanks are 22‰, 18‰, 14‰ and 10‰; Temporary breeding in a breeding pool with a salinity of 26-32‰; (3) Move the small yellow croakers to desalinated water tanks with a salinity of 22‰, 18‰, 14‰ and 10‰ in turn, keep them for 4 hours and starve them; (4 ) Move the small yellow croaker from the breeding bucket to the breeding pond with a salinity of 6‰. With this method, the desalination process can be completed within one day, and the breeding survival rate is as high as over 95%. Compared with the prior art, the time is greatly shortened, the desalination cost is reduced, and the survival rate is significantly improved.
Description
technical field [0001] The invention belongs to the technical field of seawater fish, and in particular relates to a method for artificially desalinating small yellow croakers with artificial seawater salinity. Background technique [0002] Small yellow croaker, large yellow croaker, hairtail and cuttlefish are also known as my country's "Four Seafoods" and are important economic fish along the coast of my country. The small yellow croaker is a euryhaline fish, overwinters in the deep sea in winter, migrates to the coast in spring, and after spawning in March to June, disperses in the offshore for bait, and returns to the deep sea at the end of autumn. Small yellow croaker is rich in protein, sugar, fat, calcium, phosphorus, iron, potassium, sodium, magnesium and vitamin A and other nutrients needed by the human body. Delicious, deeply loved by coastal and even inland people. [0003] With the continuous development of society, people's requirements for the freshness of fo...
