Selecting cultured adult fish or wild adult fish with excellent biological properties as parent, and culturing in an indoor cement pond or seawater net cage for 1 month; placing the cultured cuttlefish parents in an oviposition pond to lay eggs, collecting fertilized eggs, sterilizing, transferring into an incubation pond, adding chlorella into the incubation pond for incubation management, and culturing in a seedling pond after larvae are incubated out; the seedling cultivation is carried out on a large-scale full-artificial seedling cultivation by controlling the cultivation environment and the cultivation density, screening a larva cultivation bait series and feeding. The method for breeding the sepiella maindroni is suitable for large-scale artificial breeding operation of the sepiella maindroni, has the advantages of high hatching rate, high survival rate, few diseases, high breeding quantity, easiness in culture, quick growth and the like, is easy to implement and operate, has high success rate, and is suitable for large-scale popularization.
Description
Technical field
The invention belongs to cuttlefish seedling-cultivating method field, more specifically relate to a kind of Sepiella maindroni scale artificial seedling rearing method.
Background technology
Sepiella maindroni (being commonly called as inkfish) once was that China's sea fishery four big masters catch one of object, was the fishery resources of a kind of preciousness of China, since overfishing, the very big destruction of having caused resource, natural resources is obviously decayed, and output sharply descends, and is endangered.For recovering this precious species resource, Ningde City South Sea Aqua Sciences Inc. took the lead in carrying out Sepiella maindroni in Fujian Province in 2006 and grows seedlings, and successfully cultivated seed and cultured.Carried out technological innovation in 2007,2008, and obtained major progress, broken through the technology that large-scale artificial is grown seedlings " bottleneck ", reached the level of growing seedlings in enormous quantities, the amount of growing seedlings is the hat in the whole nation, has formed a kind of Sepiella maindroni scale artificial seedling rearing technology.The seed of cultivating provides ground such as Ningde, Xiapu, Fuding, Liaanjiang county, Luoyuan to carry out the breed of pond, cement pit and seawater cage isotype.This achievement; Have a series of Sepiella maindronis the grow seedlings technology and the achievement of multinomial leading domestic level; " Sepiella maindroni scale artificial seedling rearing technology " obtains Ningde City scientific and technological progress second prize; To protection and recovery marine site marine organisms diversity, advance the steady healthy sustainable development of sea fishery significant.
Summary of the invention
The objective of the invention is provides the scale artificial seedling rearing method to Sepiella maindroni; This seedling-cultivating method is applicable to the operation of growing seedlings of the large-scale artificial of Sepiella maindroni; It has that incubation rate height, survival rate are high, disease is few, the amount of growing seedlings height, be easy to culture, advantage such as growth is fast; And the operation easy to implement of this seedling-cultivating method, success rate height, suitable large-scale promotion.
A kind of Sepiella maindroni scale artificial seedling rearing method, it has following steps:
(1) parents culture: select good breed adult fish of biological character or wild adult fish as parent, in indoor cement pit or pond or seawater cage, cultivate, cultivated 1 month;
(2) artificial propagation: the laying nest that the cuttlefish parent after will cultivating is placed in the spawning pond is laid eggs; Collect fertilized egg sterilization back and move into the hatchery; In the hatchery, add chlorella and improve water quality, change water every day and carry out hatching management, treat that the young hatches the back and in nursery pond, cultivates;
(3) seed rearing: through control nurturing an environment, cultivation density, screening larval culture bait series and feeding method carry out the scale artificial seedling rearing.
The parent bodily form of selecting in the said parents culture is complete, stalwartness, body weight 100-150g.Female, male proportioning is 1:1.
The nurturing an environment of said parents culture is selected indoor cement pit or seawater cage, pond rearing; Depth of water 1.5-2m, condition of water quality are salinity 23-28, guarantee that water inlet and draining are smooth and easy; The water yield is sufficient, the water of nursery pond continues heating or recycle through boiler; Indoor Winter protection, summer ventilation and heat, through aerating machine oxygenation; The roof can draw back closed window or curtain, and is indoor through fluorescent lamp adjusting luminous intensity 50-100lux.
Said cuttlefish parent increases feeding volume 30-50% every day after parents culture is reach 1 month, and bait is good shrimp of high-quality freshness and small fish, promotes the parent gonad maturity, 50/m of parents culture density
3Bait is bait with fresh shrimp, clam worm, and daily ration, feeding quantity is 8% of a physique amount, throws something and feeds every day 2 times.The roof can draw back closed window or curtain, and is indoor through fluorescent lamp adjusting 50-100lux, keeps cultivating 18 ℃ of water temperatures.
Said artificial propagation may further comprise the steps:
1. lay eggs: suspension is with 18 in spawning pond
#Iron wire is that frame, specification are that 30 * 50cm, mesh are that the nylon mesh sheet of 1 * 1cm is made the laying nest laying nest that forms, and is used for inkfish spawning; Treat can will net the sheet taking-up after laying nest is covered with fertilized egg, the sterilization back moves into the hatchery;
2. hatching: with 1m
3Cement pit as the hatchery, will net sheet and be suspended in the water body and hatch, hatching density is ten thousand/m of 5-8
3, hydrostatic is hatched through aerating machine oxygenation.Collect the young and move into 3.3 * 8.2 * 1.5 m
3Or 4 * 9 * 1.5m
3Nursery pond grow seedlings, perhaps directly fertilized egg is placed 3.3 * 8.2 * 1.5 m
3Or 4 * 9 * 1.5m
3Nursery pond in hatch hatching density 2～30,000 ovum/m
3, directly stay former pond after the young hatches and cultivate.
Said hatching water temperature is 22-26 ℃, and salinity range is 25.7-29.7; Keep DO at 5-10 mg/ml.
It cultivates 23 ℃-30 ℃ of water temperatures said seed rearing; Between the salinity range 23.1-33.0, pH value 8.0; Ammonia nitrogen is at 0.01-0.02mg/L; Control illuminance 1000-5000Lux.Keep dissolved oxygen 5-10 mg/ml.Just incubate larval culture density and be controlled at 1.5-2 ten thousand tails/m
2, the middle and later periods is reduced cultivation density gradually, and it is 2000-5000/m that the later stage is cultivated density
3
Cuttlefish cultivation bait series is in the said seed rearing: artemia nauplii → copepoda → work mysis → dead oppossum shrimp; The step of throwing something and feeding is: the artemia nauplii of can directly ingesting when cuttlefish just incubates young opening, and food density remains on 5/ml; Throw something and feed behind 3 ages in days copepoda and nauplius thereof; Behind the long 1.2cm of cuttlefish seed trunk, begin to attempt dead bait and tame and docile food, until most of young dead bait of ingesting.
The present invention compared with prior art, the operation easy to implement of this seedling-cultivating method, incubation rate is high, survival rate is high, disease is few, the amount of growing seedlings height, be easy to culture, advantage, suitable large-scale promotion such as growth is fast.

8. a kind of Sepiella maindroni scale artificial seedling rearing method according to claim 1 is characterized in that: cuttlefish cultivation bait series is in the said seed rearing: artemia nauplii → copepoda → work mysis → dead oppossum shrimp; The step of throwing something and feeding is: the artemia nauplii of can directly ingesting when cuttlefish just incubates young opening, and food density remains on 5/ml; Throw something and feed behind 3 ages in days copepoda and nauplius thereof; Behind the long 1.2cm of cuttlefish seed trunk, begin to attempt dead bait and tame and docile food, until most of young dead bait of ingesting.
