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

[0019] A method for breeding golden pomfret includes the following steps:

[0020] (1) Put fish fry

[0021] Set up cages in the sea area. The bottom of the cage is more than 2 meters away from the seabed when the seawater is at the lowest tide level in the sea area. The salinity of the sea area is 20-30‰, the water temperature is 20-28°C, the PH value is 7-9, the transparency of the seawater is more than 8 meters, and dissolved oxygen. 5 mg / L or more; set a layer of net clothing on the net cage; clean and disinfect the net before installation; when the temperature in the sea area is 27-28 ℃, transport the fry to the sea area where the cage is located, and put it in the cage. The size of the fry stock is 1.0-1.5 cm; oxygen is added to the fry during transportation; within 2 days of the fry stock, the water flow speed in the deep sea cage is controlled to be the same as the water flow in the nursery pond. When the water flow in the sea area is faster, the water flow in the cage Ins...

Embodiment 2

[0026] A method for breeding golden pomfret includes the following steps:

[0027] (1) Put fish fry

[0028] Set up cages in the sea area. The bottom of the cage is more than 2 meters away from the seabed when the seawater is 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℃, a PH value of 7-9, and a water transparency of 8 meters , Dissolved oxygen is above 5 mg / L; Two layers of nets are set on the cages; the nets are cleaned and disinfected before installation; When the temperature in the sea area is 27-28℃, the fry will be transported to the sea area where the cages are located and placed on the nets In the box, the size of the fry is 1.5.-2.0 cm; oxygen is added to the fry during the transportation; within 5 days of the fry, the water flow in the cage is controlled to be the same as the water flow in the nursery pond. When the water flow in the sea is faster, Install a net with a smaller aperture on the cage...

Embodiment 3

[0033] A method for breeding golden pomfret includes the following steps:

[0034] (1) Put fish fry

[0035] Set up cages in the sea area. The bottom of the cage is more than 2 meters away from the seabed when the seawater is 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℃, a PH value of 7-9, and a seawater transparency of more than 8 meters. , Dissolved oxygen above 5 mg / L; set at least one layer of net clothing on the cage; clean and disinfect the net before installation; when the temperature in the sea area is 27-28 ℃, transport the fry to the sea area where the cage is located, and put it on In cages; during transportation, oxygen is added to the fry. The size of the fry is 2.0-2.5 cm; within 5 days of the fry, the water velocity in the deep-sea cage is controlled to be the same as that in the nursery pond. When the water velocity in the sea area is higher When it is fast, install a net with a smaller aper...

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 ovoid pomfret, and the local name is yellow lamb and golden pomfret. The golden pomfret is rich in nutrition, high in protein, and rich in unsaturated fatty acids, which 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 atherosclerosis, delay the body's aging, and have the effect of preventing cancer. On the usual dining table, you can often see various dishes made with golden pomfret. [0003] Golden pomfret is a warm-water pelagic fish. It has a large body size, large appetite, fast digestion, fierce feeding, and rapid growth. It starts from seedlings and can reach 400-600g in the market in 3-6 months. According to the characteristics of the fast growth o...
