Description
Technical field
The present invention relates to a kind of animal seedling-cultivating method, specifically, relate to a kind of mating system of novel juvenile stichopus, belong to the animal breeding technology field.
Background technology
The development apostichopus japonicus culture already is the important channel of development and use living marine resources, and in recent years development is very fast, and cultured area enlarges rapidly, and economic and social benefit is remarkable, has become one of important industry of China's mariculture.Manyly breed the artificial breeding that producer is engaged in stichopus japonicus, however existing mating system: the one,, breed output unstable, yield poorly; The 2nd,, the seedling body a little less than; The 3rd,, seedling specification difference is larger.Therefore further raising and the industrialization of apostichopus japonicus culture level have been restricted.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part, a kind of mating system of novel juvenile stichopus is provided.
The mating system of novel juvenile stichopus of the present invention comprises the steps:
(1) management is stored up in parent participation:
Holding pond adopts cement tub, adopts the individual layer floating cage to support temporarily, and cultivating density is 15～25/m
3, 1.2～1.5 meters of the depth of waters, 16～18 ℃ of water temperatures, salinity 29～32 ‰, pH value is 7.8～8.5, illumination 500～1000lx, dissolved oxygen is at 5 ㎎/more than the l; Parent participation every day by 4% minute of its body weight sooner or later twice sargassum thunbergii of throwing something and feeding grind liquid; Sooner or later respectively change water once every day, and each quantity of exchanged water is 1/3～1/2, changes water temperature difference and is not more than 1 ℃;
(2) spawning and fertilization:
The density of laying eggs is not more than 50/㎡, in time parent participation shifted out behind the parent participation spawning and fertilization, and with repeatedly washing ovum repeatedly through the clean seawater of sand filtration sterilization, until Chi Shui becomes clear;
(3) hatching:
Utilize phreatic water cooling tank maritime interior waters, requirement for environmental conditions is 17～20 ℃ of water temperatures, salinity 29～32 ‰, and pH value 7.8～8.5, illumination 500～1000lx, dissolved oxygen is 5 ㎎/more than the l, hatching density is 20～50/ml;
(4) seedling management:
Seedling density is controlled at 0.5～1/ml, grinds liquid with sargassum thunbergii and throws something and feeds, and changes water every day 2 times, changes water 1/2～1/3 at every turn, stirs gently up and down Chi Shui 1 time every one hour with water shoveling board, and water temperature is controlled at 20～25 ℃, 2-3 days with the clear end of siphon pipe once;
(5) young ginseng management:
(1) when growth of seedling when the former base of five tentacles or seedling 20%～30% occurring and develop into doliolaria, import and breed the pond; Select water white polyethylene corrugated plate to do adherance, water temperature remains on 15～23 ℃, and illumination is 500～1000lx, and salinity is 29～32 ‰, and dissolved oxygen is cultivated density and is controlled at 0.5～1 Tou/㎝ 5 ㎎/more than the l, pH value is 7.8～8.5
2
(2) breed the pond and adopt the flowing water method to improve water quality, every day, flowing water was 4～6 times, and each 2～3 hours, every day, streamflow was to breed 3～4 times of pond water body; Soil pick-up was 1 time in per 2～3 days, and two weeks falls pond 1 time;
(3) bait of throwing something and feeding, the bait main component is sargassum thunbergii powder, sargassum powder, fish meal, saccharomycete, ooze, immune polysaccharide and/or steel wire algae;
(4) photosynthetic bacteria of throwing something and feeding breeds the micro-ecological environment in pond with improvement, purifies water, and strengthens young ginseng resistance against diseases;
(6) the removing seed is dirty:
In seedling and young ginseng stage, it is dirty that adherance grows a large amount of salt loud, high-pitched sounds etc., in when the falling the pond clear end of stichopus japonicus, at first prepares a basin seawater, and about 5 jin of seedlings are put into basin, rotates basin water by hand, in the middle of dirty the concentrating on, fishes for 15 centimetre of 100 little fishing net of order of diameter.
Preferably, described adherance sodium hydroxide solution with 0.5 ‰-1.0 ‰ before input soaked 2～3 days, then wash with liquor potassic permanganate and brush one times, rinse well with filtering sea again, put into after washing and breed the pond and inoculate benthic diatom, stir transfixion, be inverted adherance next day, the inoculation another side.
The mating system of novel juvenile stichopus of the present invention has following technique effect: the present invention utilizes phreatic water cooling tank maritime interior waters in the hatching stage, has avoided water temperature over-high, good seedling living environment is provided, improved survival rate, survival rate can reach 90%, and what assurance was bred carries out smoothly.The photosynthetic bacteria of throwing something and feeding in the pond is effectively improved the micro-ecological environment of breeding the pond, purifies water, and strengthens young ginseng resistance against diseases.Select water white transparency, ripple is high, area is large polyethylene corrugated plate to do adherance, be beneficial to and adhere to and ingest.Adopt special method removing seed dirty, reduce water pollution, promote to grow and survive.Adopt the present invention, the one, growth time is long.Owing to utilizing underground sea water regulation and control water temperature, guaranteed that seedling grows under the matters temperature, avoided the aestivation winter of seedling to bite, can prolong wheat harvesting period in vegetative period 5, thus long fast, individual large of seedling, the young ginseng of the 2cm 4cm-6cm that can grow up, large individuality can reach 8cm.The 2nd, survival rate is high, and is good in economic efficiency.Owing to the living condition of young ginseng has been carried out full artificial regulatory, so survival rate of seedlings is high, generally can reach about 30%.
