Problems solved by technology

Since the cultivation of fry and later breeding are carried out in different areas, the environmental conditions vary greatly. At the same time, fry need to be transported for a long distance, which not only greatly increases the cost of breeding, but also easily produces stress reactions or infection of various diseases, which seriously affects The economic benefits of farming

Embodiment 1

[0026] A kind of gold pomfret breeding method, comprises the following steps:

[0027] (1) Add fry

[0028] Set up net cages in the sea area. The bottom of the net cage is more than 2 meters away from the sea bottom when the sea water is at the lowest tide level in the sea area. 5 mg / L or more; set a layer of netting on the net cage; clean and disinfect the net before installation; when the temperature in the sea area is 27-28°C, transport the fry to the sea area where the net cage is located, and put them in the net cage. The feeding size of the fry is 1.0-1.5 cm; add oxygen to the fry during transportation; within 2 days of putting the fry, control the water flow speed in the deep sea net cage to be the same as the water flow speed in the nursery pond. Add nets with smaller apertures; when the water flow in the sea area is slow, remove the additional nets to make the fry adapt to the environment in the sea area; then gradually remove the additional nets within 5-7 days to m...

Embodiment 2

[0033] A kind of gold pomfret breeding method, comprises the following steps:

[0034] (1) Add fry

[0035] Set up cages in the sea area. The bottom of the cages is more than 2 meters away from the bottom of the sea at the lowest tide level in the sea area. The selected sea area has a salinity of 20-30‰, a water temperature of 20-28°C, a pH value of 7-9, and sea water transparency of more than 8 meters. , the dissolved oxygen is more than 5 mg / L; two layers of nets are set on the net cages; before the nets are installed, they are cleaned and disinfected; when the temperature in the sea area is 27-28 °C, the fry are transported to the sea area where the net cages are located and put into the nets. In the box, the size of the fish fry is 1.5.-2.0 cm; oxygen is added to the fry during transportation; within 5 days of putting the fish fry, the water flow speed in the cage is controlled to be the same as the water flow speed in the nursery pond. When the water flow speed in the sea...

Embodiment 3

[0040] A kind of gold pomfret breeding method, comprises the following steps:

[0041] (1) Add fry

[0042] Set up cages in the sea area. The bottom of the cages is more than 2 meters away from the bottom of the sea at the lowest tide level in the sea area. The selected sea area has a salinity of 20-30‰, a water temperature of 20-28°C, a pH value of 7-9, and sea water transparency of more than 8 meters. , the dissolved oxygen is more than 5 mg / L; set at least one layer of netting on the net cage; clean and disinfect the netting before installation; when the temperature in the sea area is 27-28 °C, transport the fry to the sea area where the net cage is located, and put it in In the net cage; add oxygen to the fry during transportation, and the frying specification is 2.0-2.5 cm; within 5 days of putting the fry, control the water flow velocity in the deep-sea cage to be the same as the water flow velocity in the nursery pond. When the water flow velocity in the sea area is rel...

Abstract

The invention relates to the field of aquaculture, particularly to a golden pomfret cultivating method. The method comprises the steps of controlling cultivating conditions, additionally installing meshes, screening, changing netting and the like in a fry putting process and the daily management process, enabling the golden pomfret fry to quickly adapt to the growing environment in the sea area, thereby the fry can be directly put in the deep sea area for realizing deep sea cage, the growth process of the golden pomfret from fry to finished fish is completed in the same environment, the cost of repeated transport is reduced, the stress response of the golden pomfret caused by the change of environment is also reduced, the morbidity and mortality are greatly lowered, drug prevention is not needed in the whole farming process, the growth environment of the golden pomfret is near to the wild condition, and the quality of the commodity is greatly improved.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a golden pomfret breeding method. Background technique [0002] The scientific name of golden pomfret is egg-shaped pomfret, and the local names are yellow waxed pomfret and golden pomfret. Golden Pomfret is rich in nutrition, high in protein, rich in unsaturated fatty acids, and has the effect of lowering cholesterol. At the same time, golden pomfret is rich in trace elements selenium and magnesium, which can prevent cardiovascular diseases such as coronary arteriosclerosis, delay the aging of the body, and have the effect of preventing cancer. Various dishes cooked with golden pomfret are often seen on the usual dining table. [0003] Golden pomfret is a warm-water pelagic fish with a large body size, large appetite, fast digestion, and ferocious feeding. It grows rapidly. It can be cultivated from seedlings, and it can reach the market size of 400-600g in 3-6 months. Farmers Acco...
