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...

Description

Technical field: [0001] The invention relates to a freshwater culture method for seawater fish. Background technique: [0002] Takifugu flavidus is an aquatic product with high economic value. It has high protein content, tender meat and rich nutrition. It is an important economic fish for coastal people's consumption and foreign trade export. The chrysanthemum yellow oriental porpoise sold in the market comes from offshore fishing. Due to high prices for many years, fishermen have overfished and overfished, resulting in a sharp decrease in resources and the gradual miniaturization of individuals. Invention content: [0003] The object of the present invention is to provide a kind of chrysanthemum chrysanthemum that can form large-scale production Low-salinity artificial seedling cultivation and freshwater aquaculture methods. [0004] Technical solution of the present invention is: [0005] A low-salinity artificial seedling raising and freshwater culture method for ...
