Embodiment 1

[0019] A large-scale full-scale artificial cultivation method for Mansfield squid, the specific implementation steps of the present invention are:

[0020] (1) Select the breeding mode: select seawater cages for breeding;

[0021] (2) Cleaning and disinfection before placing seedlings;

[0022] (3) Seed transportation and stocking: Seeds can be transported by oxygenated polyethylene plastic bags (40cm×70cm). Each bag contains 200 seedlings. For longer transportation time, use a running water truck. The temperature difference should not exceed ±3°C; the water temperature is 13°C and the salinity is 26. For the seedlings, it is not suitable to put the seedlings in strong wind and rainstorm days. The seedlings are stocked in May to control the stocking density;

[0023] (4) Breeding management: control the temperature at 25°C, salinity at 26, pH value 6.8, dissolved oxygen (DO) 5 mg / L, ammonium nitrogen 0.2 mg / L, hydrogen sulfide 0.05 mg / L, and feeding the sea Catch small fish ...

Embodiment 2

[0032] A large-scale full-scale artificial cultivation method for Mansfield squid, the specific implementation steps of the present invention are:

[0033] (1) Select the breeding mode: select the indoor cement pond for breeding;

[0034] (2) Cleaning and disinfection before placing seedlings;

[0035] (3) Seedling transportation and stocking: Seedlings can be transported by oxygenated polyethylene plastic bags (40cm×70cm), 300 seedlings per bag, and live water boats and vehicles for longer transportation time, and the temperature is controlled at 25°C, and the water temperature is the same as The outside temperature difference should not exceed ±3°C; the water temperature is 13°C and the salinity is 26 for seedlings.

[0036] (4) Breeding management: control the temperature at 25°C, salinity at 27, pH value 7.2, dissolved oxygen (DO) 5 mg / L, ammonium nitrogen 0.2 mg / L, hydrogen sulfide 0.05 mg / L, and water quality regulation , feeding sea-caught small fish and shrimp as fee...

Embodiment 3

[0045] A large-scale full-scale artificial cultivation method for Mansfield squid, the specific implementation steps of the present invention are:

[0046] (1) Select the breeding mode: select the indoor cement pond for breeding;

[0047] (2) Cleaning and disinfection before placing seedlings;

[0048] (3) Seed transportation and stocking: Seeds can be transported by oxygenated polyethylene plastic bags (40cm×70cm), with 300 seedlings per bag. For longer transportation time, use running water boats and vehicles, and control the temperature to 28°C, and the water temperature to be equal to The outside temperature difference should not exceed ±3°C; the water temperature is 13°C and the salinity is 28 for seedlings.

[0049] (4) Breeding management: control temperature at 25°C, salinity at 26, pH value 7.0, dissolved oxygen (DO) 6 mg / L, ammonium nitrogen 0.2 mg / L, hydrogen sulfide 0.05 mg / L, and water quality regulation , feeding sea-caught small fish and shrimp as feed, contro...

Abstract

The invention discloses a scale full-artificial-breeding method for sepiella maindroni. The scale full-artificial-breeding method comprises five steps, such as selection of breeding mode, cleaning and sterilizing before offspring seeds feeding, transporting and stocking of the offspring seeds, breeding management as well as harvesting and transporting. The scale full-artificial-breeding method comprises the specific steps of: breeding in selective seawater net cage, pond or indoor cement pit and cleaning and sterilizing before offspring seeds feeding; oxygenating and transporting the offspring seeds by using polyethylene plastic bags, controlling the temperature and the salinity and feeding the offspring seeds and controlling the stocking density; controlling parameters such as the temperature, the salinity, the pH values and the like during breeding management; regulating and controlling the water quality, feeding small fish shrimps captured from the sea as feed; controlling the feeding amount and the feeding time and preventing diseases; breeding for 3-4 months and stopping feeding for one day before harvesting; and transporting by adopting a flowing water vehicle. The scale full-artificial-breeding method is suitable for the scale full-artificial-breeding operation of the sepiella maindroni and has the advantages of high survival rate, fewer diseases, easiness for breeding,strong disease resistance, high growth speed and the like. In addition, the scale full-artificial-breeding method is easy for implementation and operation, is high in survival rate and is suitable for large-scale popularization.

Description

technical field [0001] The invention belongs to the field of squid breeding methods, and more specifically relates to a large-scale full-artificial breeding method for squid without needles. Background technique [0002] Mansoni's needleless squid is the best variety among more than one hundred kinds of squid, commonly known as "authentic cuttlefish" and known as "marine treasure". It is delicious in meat, rich in nutrition and high in economic value. It is a precious fishery resource in our country. , but due to overfishing and environmental reasons, the resources of squid mansoni in my country have been greatly damaged and have tended to be exhausted. In order to restore this precious species resource, Ningde Nanhai Fishery Technology Co., Ltd. took the lead in cultivating a kind of needleless squid in Fujian Province in 2006. In 2009, it began to carry out large-scale artificial cultivation of Squid Mansoni in China, which broke through the technical difficulties of full-...
