Abstract
The invention provides a pseudobagrus fulvidraco fry culture method. The method includes the steps that firstly parent fishes are collected and put in a special pond for culture, water flushing is carried out once every 2-3 days 2 months after the parent fishes are cultured, the parent fishes with consistent maturity are picked, exogenous hormones are injected, and then the parent fishes are stocked in a breeding pond; female fishes start to spawn, hatching and stripping are carried out, then fry appear, micro-running water is kept, and it is guaranteed that dissolved oxygen is sufficient during hatching; after the fry are hatched, the fry are cultured in the breeding pond, when summer fingerlings grow to 3 cm, stocking is carried out, feeding domestication is immediately carried out after stocking is carried out, and after feeding domestication succeeds, normal culture is carried out. According to the scientific and reasonable pseudobagrus fulvidraco fry culture method, the parent fishes are selected to be cultured in the special pond, the egg laying and sperm producing quality of the parent fishes can be improved, egg laying and sperm producing of the parent fishes are promoted through the effects of the exogenous hormones, and the number of zygotes is increased. The fry are subjected to feeding domestication in time after being hatched and stocked, the physique of the fry can be improved, and the feed utilization rate can be increased.
Description
Technical field
The present invention relates to aquaculture field, more particularly to a kind of Pelteobagrus fulvidraco offspring seed cultivation method.
Background technology
Pelteobagrus fulvidraco is a kind of small-sized fresh-water fishes, be bottom dwell, predacious fish, be widely present in China's poisons in freshwater, its meat
Fresh thorn less, matter it is delicate, without fishlike smell, delicious, be of high nutritive value, not only have tonic effect, and also certain medicinal valency
Value, at home and abroad market is well received.In natural water area, yellow catfish growing speed is slower, and listing specification is less, and market is not for
Should ask.In recent years Culture of Pelteobagrus Fulvidraco industry has certain development, and the cultivation of wherein fry is the important of artificial cultivation Pelteobagrus fulvidraco
Link, the height of emergence rate largely have impact on the yield of cultivation Pelteobagrus fulvidraco.Therefore need to take into full account the habit of Pelteobagrus fulvidraco
Property, the selection-breeding parent fish of science until spawning, fertilization, hatching, to cultivate high-quality, high yield fry.
The content of the invention
Present invention seek to address that the deficiencies in the prior art, and a kind of Pelteobagrus fulvidraco offspring seed cultivation method is provided.
The present invention for achieving the above object, is employed the following technical solutions：A kind of Pelteobagrus fulvidraco offspring seed cultivation method, its feature exists
In its step is as follows：
(1) from the artificial cultivation water surface parent fish is collected in the winter time, it is desirable to which parent fish body colour is bright-coloured, side speckle is distinct, disease-free
Without wound, wherein male and female quantitative proportion is 1:1.5, the parent fish collected is then placed in 3% Sal 10～15min of water dipping bath
Specially pond is cultivated, and the pond depth of water requires 1.2～1.5m, starts to be washed by water 1 time per 2～3 days after cultivating two months；
(2) select that bed mud is shallow, retain water and nutrients, have abundant water resources, pond that water quality is good is as breeding pond, pond depth 1.5m, use
Quick lime carries out sterilization of cleaning up the pond, and after the property of medicine disappears, with 60 mesh silk cover filterings 60～80cm is added water to, and with brown piece pond is pressed on
Bottom, uses submerged plant binding in pond, be uniformly distributed at culture pond surrounding 50～60cm depth of waters, as the things concealed of Gunther parent fish spawning
Attachment after hatching with fry, sets aerator in pond；
(3) the consistent parent fish of Maturity is selected, wherein raun requires that the bodily form is plentiful, abdominal part expands soft, and high resilience,
Substantially, milter requires physique healthy and strong to ovary profile, and body colour is gorgeous, and to parent fish exogenous hormone is injected, and then presses milter and raun
Put in a suitable place to breed and bred in pond in pond according to the breeding density of 1 Wei/㎡；
(4) parent fish after exogenous hormone is injected, control water temperature starts fish roe Jing 42～70 after spawning little at 24～27 DEG C
When, you can whole hatching demouldings, there is fry, start hatching to membrane, splashed ovary 1 time with methyl blue liquid daily, in case
Fish roe is mouldy, while keeping miniflow water, it is ensured that dissolved oxygen is sufficient during hatching；
(5) after fry hatches, through cultivating in pond is bred, body length reaches 2～3cm for summer flower fingerling；
(6) after summer flower fingerling length is to 3cm, put in a suitable place to breed, breeding density is 20,000～2.5 ten thousand tails/mu, after putting in a suitable place to breed immediately
Carry out taming and dociling food, taming and dociling food method is：First dough is fed in pond side, every 2m 1 is thrown in, focus in dough after 4～5 days
At one, after fry is concentrated, buoyancy expanding pellet is fed with Autoamtic bait putting machine, domestication Pelteobagrus fulvidraco floats and robs food；
(7) tame and docile food success after, feed daily 2 times, feeding volume for pond fish body weight 5%～10%, according to weather, water quality and
Situation of ingesting flexibly increases and decreases.
Particularly, it is to the exogenous hormone of parent fish injection in the step (3)：To every kilogram of raun injection Cyprinus carpio, Medulla Carassius auratuss
The μ g of hypophysis 1～3mg+ maleic acid DOM 1～3mg+ luteinizing hormone releasing hormones analog 5～15, milter injection volume is raun agent
The 70% of amount.
Particularly, in the step (5), 50～100cm of the depth of water, more than dissolved oxygen 5mg/L, day are required during fry rearing
Throw feedstuff and account for the 3%～5% of pond fish body weight.
The invention has the beneficial effects as follows：The invention provides a kind of scientific and reasonable Pelteobagrus fulvidraco offspring seed cultivation method, selects
Special pond cultivation is carried out after parent fish, the spawning of parent fish is favorably improved, is produced extract Iuality, Gunther parent fish spawning is promoted by exogenous hormone effect
Essence is produced, germ cell quantity is improved；Fry hatching carries out in time taming and dociling food after putting in a suitable place to breed, is favorably improved fry body constitution and feed conversion
Rate.
