Embodiment 1

[0038] A method for cultivating scorpionfish in cages, comprising:

[0039] (A) Cultivation of scorpionfish fingerlings: select artificially bred scorpionfish fry, use live mysis shrimp as bait in net cages in sea areas, and then domesticate the bait, and cultivate them into scorpionfish fingerlings for breeding;

[0040] (B) Cultivation and management of scorpion scorpionfish: Breed scorpion scorpionfish fingerlings into net cages in sea areas by feeding chilled miscellaneous fish and shrimp bait to breed scorpion scorpionfish commercial fish.

[0041] The body length of the scorpionfish fry in the step (A) is 2.0-2.4cm, and the feeding amount of the scorpionfish fry is 8000 fish / box.

[0042] The specifications of the sea area cages used in the step (A) are 2-4m×2-4m×3-5m (depth), and the mesh of the cages is 0.3-0.5cm.

[0043] The feeding amount of live mysis in the step (A) is 4-6 kg each time, and feeding is once every 3 days.

[0044] The bait domestication in the ste...

Embodiment 2

[0050]The seawater conditions in the steps (A) and (B) are water temperature 28.6°C, salinity 29.5, pH value 8.12, dissolved oxygen 5.40mg / L, ammonia nitrogen content 0.053 mg / L, flow velocity 0.1~0.2m / s, The stocking quantity of scorpionfish fry is 12,000 / box, and the stocking quantity of scorpionfish fingerlings is 5,000 / box.

[0051] The parts not mentioned above are the same as the specific embodiments.

Embodiment 3

[0053] The seawater conditions in the steps (A) and (B) are water temperature 21°C, salinity 28, pH value 7.91-8.12, dissolved oxygen 7.5 mg / L, ammonia nitrogen content 0.042 mg / L, flow rate 0.1-0.2m / s, the feeding amount of scorpionfish fry is 10,000 / box, and the feeding amount of scorpionfish fingerlings is 4,000 / box.

[0054] The parts not mentioned above are the same as the specific embodiments.

[0055] The above descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the present invention.

Abstract

The invention particularly relates to a cage culturing method of inimicus japonicus, which comprises the following steps of: (A) the cultivation of inimicus japonicus fingerlings: selecting artificially cultured inimicus japonicus fish fries, taking live opossum shrimps as baits in cages of a sea area, followed by acclimatizing the inimicus japonicus fish fries through the baits, and breeding the inimicus japonicus fish fries to be inimicus japonicus fingerlings for cultivation; and (B) cultivation and management of the inimicus japonicus: cultivating cultivated inimicus japonicus fingerlings to be inimicus japonicus commercial fishes through feeding chilled miscellaneous fish and shrimp baits in the cages of the sea area. The method is simple and convenient and is easy to learn; the survival rate of fingerlings after the bait acclimatization is finished is 73.3%; the average weight of the fingerlings is 1.82g; the survival rate of the inimicus japonicus commercial fish is 35.8%; the average weight of the inimicus japonicus commercial fish is 205g; the weight of the heaviest inimicus japonicus commercial fish is 26g; and the cultivated commercial fishes have a higher economic value.

Description

technical field [0001] The invention belongs to the field of aquaculture, and more specifically relates to a method for cultivating scorpionfish in net cages. Background technique [0002] Compared with algae, shellfish and shrimp culture, my country's marine fish cage culture started relatively late, but it has developed rapidly. At present, cage fish culture is one of the main methods of marine culture. Seawater cage aquaculture has the characteristics of intensification, high density, and high benefit, and is the main force of emerging industries in my country's aquaculture industry. According to incomplete statistics, the fish species currently suitable for cage farming are: red bream, black bream, pepper bream, yellowfin, six-line fish, perch, barramundi, grouper, rainbow trout, coho salmon, tilapia Fish, flounder, turbot, sixfinger threadfin, yellow croaker, large yellow croaker, kingfish, European eel, golden pomfret, American redfish. [0003] Ghost scorpionfish ( ...
