Embodiment

[0017] A low-salinity artificial seedling raising and freshwater culture method for puffer chrysanthemum, comprising the following steps in sequence:

[0018] (1) Breeding of broodstock: Select the chrysanthemum yellow puffer that has reached the age of 2 and place it in a salinity of 12‰~8‰ (example 12‰, 10‰, 8‰), pH7.0~8.5 (example 7.0, 7.4, 7.7, 8.0 , 8.2, 8.5), water temperature 16 ~ 24 ℃ (example 16, 18, 20, 22, 24 ℃) in the pool, the bait uses rotifers (or eel feed, surimi, fish meal, the above bait can also contain vitamin and / or vegetable oil), the daily feeding amount is about 4% to 6% of the broodstock weight (eg 4%, 5%, 6%);

[0019] (2) Artificial insemination and hatching: first inject hormones into the broodstock to induce labor, and the injections are divided into two times, and inject LRH-A to the female broodstock for the first time 2 15-30 μg / Kg (Example 15, 20, 25, 30 μg / Kg). Male broodstock are exempt from injection, and the second injection is 4 to 7 hou...
