Breeding technology of horse-faced puffer

The breeding technology of horse-faced puffer (green-fin horse-faced puffer) involves many aspects, including breeding conditions, breeding technology, nutrition enhancement, light control, water quality management and disease prevention and control. The following is a detailed introduction:

Breeding sites and breeding conditions. The breeding of horse-faced puffer needs to be carried out in high-quality factory nursery workshops, which should have suitable water quality and temperature conditions, as well as good oxygenation facilities. There are also specific requirements for the size and shape of the brood breeding pool, hatching pool and fry breeding pool. The water source is subject to multi-stage sand filtration to ensure clean water quality.

Parental selection. The horse-faced puffer with a body weight of 300g ~ 500g, pure body color, no injury and no disease was selected as the parent.

Nutritional fortification. During the breeding period of parent fish, suitable bait such as sand silkworm, oyster meat and shrimp meat should be fed, and the water quality should be changed regularly.

Spawning and hatching. The mature male and female horse-faced puffer are mixed in a certain proportion for artificial reproduction.

Seedling cultivation. The seedling cultivation of horse-faced puffer can be carried out in a land-based factory culture greenhouse or in a high-level pond. Need to control the appropriate light intensity and water temperature. Regularly change the water quality, remove the residual bait and feces, and keep the water clean.

Sub-pool. When the fry length reaches 3 to 5cm, it needs to be cultured in separate ponds to avoid overcrowding and competition for food.

Disease prevention. Regularly check the health status of horse-faced puffer, timely detection and treatment of disease.

Commercial fish cultivation. When the fry length reaches more than 5cm, it can enter the stage of commercial fish cultivation, which may need to be transferred to a larger pond or seawater cage.

Through this breeding technology, the yield and quality of horse-faced fish can be effectively improved to meet market demand.
