A kind of breeding method of pseudorasbora parva open-mouthed bait
Technical field
The present invention relates to the breeding method of a kind of pseudorasbora parva open-mouthed bait, belong to technical field of aquaculture.
Background technology
Pseudorasbora parva (Pseudorasboraparva), because of its delicious meat, is increasingly subject to people and likes, climbs up and up in market price, reaches 28 yuan/kg.The adult fish of the sold pseudorasbora parva in market is main mainly by fishing for, artificial propagation is few, therefore the artificial breeding research carrying out pseudorasbora parva is of great importance, and the key of pseudorasbora parva artificial breeding solves its open-mouthed bait exactly, whether open-mouthed bait is agreeable to the taste, whether nutrition directly affects pseudorasbora parva nursery success or not comprehensively, but the cultivation of pseudorasbora parva open-mouthed bait is a great problem of existing cultural technique.
Summary of the invention
It is an object of the invention to as solving a pseudorasbora parva open-mouthed bait cultivation difficult problem, it is provided that the breeding method of a kind of pseudorasbora parva open-mouthed bait.
The technical solution used in the present invention is as follows:
The breeding method of a kind of pseudorasbora parva open-mouthed bait, comprises the following steps:
(1) cultivate pond to select
Culture pond should select to be built near nursery, traffic convenience, has abundant water resources, and depth of water building width, irrigation and drainage are conveniently, the pure and fresh place of water quality, pond shape rectangle, substrate should be non-leakage shale or argillo arenaceous as well, at the bottom of pond and pool wall non-leakage, and smooth at the bottom of pond, embankment is firm, and area is 2000-3000m2, tank depth is 1-1.2m;
(2) clear pond
Being divided into the clear pond of solid carbon dioxide and two kinds of the clear pond of band water, Chi Shui is drained by the clear pond of solid carbon dioxide, after being exposed to the sun 1 week, splashes with disinfectant water, and the clear pond of band water adds disinfectant by water body amount and kills harmful organisms;Disinfectant consumption is 35-40g/m3, within drug effect 3-5 days, disappear;
(3) water inlet
After clear pond drug effect disappears, for preventing harmful animal entrance, the bolting silk net filtration of 200-250 order need to being used to add Chi Shui, the initial stage, the depth of water was at 30-40cm, was stepped up subsequently;
(4) fertilising
Conventional fertile class divides fertilizer and inorganic fertilizer, and amount of application is determined according to pond regimen condition, should duty execute on a small quantity, it is desirable to method adopts fertilizer and inorganic fertilizer mixing to use.Manure type selects homemade fermentation fertilizer, and the consumption of fermentation fertilizer is 250-300g/m3, during fertilising, first the fermentation fertilizer of 1/2 being uniformly spread in pond, all the other 1/2 pile up pond surrounding, rely on rainwater to make nutriment in a fertilizer flow into slowly in pond, after having executed base manure, within every 2 weeks, use carbamide 20-25g/m3, after fertilising 3-5 days, water colour by clear thin out green or light brown, a large amount of algae bio flourish;
(5) inoculating rotifer
When natural temperature reaches 10-15 DEG C, and Chi Shui is more fertile can inoculating rotifer in good time, select fine day water temperature in afternoon to carry out time the highest during inoculation, comparatively suitable with 0.5-1/ml;
(6) training orientation
A, supplementary fertilizer: accelerating along with water temperature raises algae reproduction, nutrient salt in water consumption comparatively fast needs timely supplementary fertilizer, selects fine day to carry out afterwards before midday, and consumption is depending on water quality situation, and a small amount of duty is executed;
B, wheel are caught: along with the amount reproduction of wheel animalcule in pond, need to catch control wheel animalcule density by wheel, make unicellular alga maintain suitable density, it is ensured that the nutrition that water body is enough;
C, oxygen supplement: when wheel animalcule quantity is more than 2 × 104Individual/L time, it is necessary to drive aerator, mainly at dead of night with overcast and rainy unlatching, it is ensured that pond water-soluble oxygen is more than 3mg/L;
D, disease control: the disease of wheel animalcule is primarily referred to as harmful animal, it is necessary to put prevention first, mainly take thoroughly to clean up the pond, the method for strict drainage;
(7) harvesting
The trawlnet made of the bolting silk of 200-250 order, fishes along pool side towing, it is possible to utilizing wheel animalcule phototaxis, utilize strong light irradiation night, at wheel animalcule concentration place, bucket is tracked down and recovered.
The preparation method of described disinfectant is as follows: weigh the raw material of following weight portion: Radix Angelicae Dahuricae 3-5, Radix Saposhnikoviae 2-3, Fericarpium Citri Limoniae 4-6, Radix Stemonae 1.5-2.5, Celastrus angulatus 2-4, Rhizoma Atractylodis 1-3, Radix Granati 3-6, Folium Populi Pseudo-simonii 2-3, Herba Schizonepetae 4-7, Herba Artemisiae annuae 3-5, above-mentioned raw materials is mixed, pulverized 100-150 mesh sieve, then add 5-10 times amount water big fire and boil a turn medium and small fire decoction 40-60min, filter, the sepiolite powder of 4-8% is added in filtrate, the blanc fixe of 3-6% and the pyrophyllite powder of 2-4%, heating in water bath is to 80-90 DEG C, speed lapping 20-30min, it is spray dried to powder, then in powder, add the bleaching powder of 10-15% and the potassium permanganate mix homogeneously of 5-10%.
The preparation method of described fermentation fertilizer is as follows: (1) weighs the raw material of following weight portion: chicken manure 40-60, powdered rice hulls 15-25, Semen arachidis hypogaeae dregs 10-15, sunflower disc 5-10, maize cob meal 8-12, Folium Viciae fabae powder 3-6, brown coal powder 2-4, Folium Chrysanthemi slag 4-8, soy sauce residues 3-5, Bamboo vinegar solution 2-3, blackstrap 3-6, zeolite powder 5-8, turfy soil 4-6, calcium superphosphate 2.5-3.5, ammonium nitrate 2-3, Spirulina powder 2-3, beet root powder 1-2;(2) by chicken manure, Semen arachidis hypogaeae dregs, sunflower disc, Folium Chrysanthemi slag and soy sauce residues mix homogeneously, then the 3-5% pressing compound weight adds 100-150 times of EM bacterium dilution of stock, stir, then add powdered rice hulls, maize cob meal, Folium Viciae fabae powder, brown coal powder, Bamboo vinegar solution, blackstrap, zeolite powder and turfy soil, mix to hold agglomerating, webs water breakthrough but not Rhizoma pinelliae cordatae, loose one's grip and namely dissipate as well, mixed fermentation material is put into compost fermentation in fermentation vat, temperature controls at 30-35 DEG C, turning every day 2 times, after fermentation in 10-15 days completes;(3) fermentation material obtained in step (2) adds calcium superphosphate, ammonium nitrate, Spirulina powder and beet root powder, stirs and is fermentation fertilizer.
Beneficial effects of the present invention:
The present invention utilizes biological organic fertilizer to cultivate wheel animalcule, large amount of organic in accelerated decomposition water, increase dissolved oxygen in water, reduce water pollution, promoting the fast-growth of wheel animalcule, survival rate is high, and the wheel animalcule comprehensive nutrition cultivated, good palatability, the large scale cultivating for pseudorasbora parva open-mouthed bait provides a solution.
