Summary of the invention
The present invention raises and train problem for wild blackspot Yuan Select-Committee adult fish, provides a kind of domestication of wild blackspot Yuan Select-Committee adult fish
Method is targetedly tamed, strong operability, practical application is good, Ke Yishi according to the feature of wild blackspot original Select-Committee
The scale and standardization of existing wild blackspot Yuan Select-Committee adult fish are raised and train, and the development of Lhasa blackspot Yuan Select-Committee aquaculture, effective protection are promoted
Draw blackspot Yuan Select-Committee wild resource.
The technical solution adopted by the present invention is that:
A kind of acclimation method of wild blackspot Yuan Select-Committee adult fish, includes the following steps:
1) collection of fish is planted
The kind fish come will be collected to be placed in storage pond, holding pond, injection broad spectrum antibiotic prevents inflammation from infecting, and injects 1 time within every 3 days, even
2-3 times continuous, body surface normally enters to raise and train in pond afterwards feeds；
2) kind fish domestication
Fish anesthesia will be planted with anesthetic, will be poured into the natural bait minced in its stomach with soft plastic dropper, weekly 1
It is secondary, during which continue to feed live fish, observing terminates dropper feeding when blackspot Yuan Select-Committee can be preyed on actively, the kind fish after domestication every
Feeding live fish is primary within 3-4 days；The intramuscular injection of a broad spectrum antibiotic is carried out to kind of fish every two weeks.
During forcing to fill food, it can keep always with the presence of bait fish in cylinder, if observing, bait fish quantity is significantly reduced
Then illustrate that blackspot Yuan Select-Committee actively ingests；Bait fish can also be put after filling food 3-4 days, may observe that blackspot Yuan Select-Committee is caught personally
Food.
Anesthetic of the present invention is MS-222, other anesthetic have certain risk, anaesthesia dosage 0.08-
0.2g/L。
Pool inner water temperature of the present invention of raising and train is 8-15 DEG C, and water body keeps the salinity of 5-12 ‰, and the ammonia nitrogen concentration of water body is not
Higher than 0.5mg/L, nitrite concentration is not higher than 0.05mg/L, pH value 7-8.Wild blackspot Yuan Select-Committee lives in rapid limpid
River water in, higher to water quality requirement, daily raising should select tap water or water quality is good, sterile other nontoxic water sources.
Blackspot Yuan Select-Committee is cold water fishes, and more sensitive to water temperature variation, can be gradually dead when water temperature is more than 18 DEG C；It keeps
The salinity of 5-12 ‰, to prevent the generation of various nosomycosises, bacterial disease.
Of the present invention to raise and train the fishpond that pond is inner wall smooth, bottom, which is laid with bed load or places smooth stone and be used as, hides
Object, all objects have to smooth and easy to clean.
The water surface distance Chi Ding of the present invention for raising and train pond is not less than 0.5m, and blackspot original Select-Committee has certain climbing ability,
Can cover prevents from escaping.
Natural bait of the present invention is chironomus larvas, and each feeding amount accounts for kind of a 3-5% for fish body weight.
The reason of selecting chironomus larvas: 1, wild blackspot Yuan Select-Committee is predacious fish, the small fishes and aquatic of mainly ingesting
Arthropod etc., chironomus larvas is also in recipe range；2, the flesh of fish is such as selected, then is picked a bone cumbersome, if rejecting is not clean to hurt
To blackspot Yuan Select-Committee；3, in common biological feed (chironomus larvas, water earthworm, cladocera, Copepods etc.), chironomus larvas size
Properly, full of nutrition, annual to buy, and predominantly frozen goods, safety are preferable.
Feeding amount accounts for the 3-5% of its weight every time after present invention domestication.Blackspot Yuan Select-Committee is predacious fish, is fond of Tibet sheet
The small-sized benthic fishes such as the Triplophysa on ground, but blackspot Yuan Select-Committee digestion power is poor, so feeding should not be excessive, excessively diligent.
Live fish is dipped to bait fish body with the salt water of 30 ‰ or more concentration and lain on one's side by the present invention before feeding live fish,
Until powerless struggle, prevent pathogen from entering breeding water body.
Blackspot original Select-Committee is all sensitive to current various commercially available mould drugs of harnessing the river, and therefore, it is difficult to be treated with drug immersion way.When
There is the symptom of saprolegniasis in kind fish, and macroscopic mycelium occurs in the skin surface for planting fish, when pulling sick fish out, in lesion
Salt is smeared at place, is put back in water after 15s, and gentamicin is injected after 1h prevents inflammation, if next day still sees that mycelium can continue to smear salt, is repeated
For several times until recovery from illness.
Corpus luteum disease is the peculiar disease of blackspot Yuan Select-Committee, and entire body becomes golden yellow in the sick fish short time, is slow in action, in 1-2 days
Can be dead, etiology unknown at present.When the symptom of corpus luteum disease occurs in kind of fish, gentamicin is injected at once, it is usually primary
It takes effect.
It is unobvious that blackspot Yuan Select-Committee infects small melonworm initial stage body surface symptom, but has obvious white point at the gill filament, gill filament face when serious
Discoloration is shallow and has petechial hemorrhage, and skin surface is dotted or patch shape falls off.0.5g/m should be used at the initial stage of a disease3The ginger of water body,
Capsicum mixture full pool spilling head, continuous a few days to polypide disappear, if during which seeing skin exfoliation symptom, should inject in time gentamicin and disappear
It is scorching.
Blackspot Yuan Select-Committee die by visitation of God is met, and should dissect and check liver when body surface non-evident sympton, if liver lighter,
It may be poisoning, check water quality index at this time, change water in time, and subtract if nitrite is more than 0.1mg/L if any exception
Few feeding amount.
Broad spectrum antibiotic of the present invention is gentamicin sulphate, and injection dosage is 0.5 ten thousand units/kg weight, safety
Property it is high.
The beneficial effects of the present invention are:
1, blackspot Yuan Select-Committee skin fragility catches, is easily injured in transportational process, only conventional soaking disinfection and clear water raising
Method, the death rate within blackspot Yuan Select-Committee two months are likely to be breached 100%.Therefore the present invention is to newly into kind of a fish injection broad-spectrum antiseptic
Medicine prevents inflammation from infecting, while for blackspot Yuan Select-Committee to most medicaments insensitives, once it is sick difficult to treat, it takes and puts prevention first
Mode carries out the intramuscular injection of a broad spectrum antibiotic to kind of fish every two weeks, ensure that the health of kind of fish, raising survives
Rate,
2, since wild blackspot Yuan Select-Committee is timid easily frightened, stress reaction is heavier, newly tends not to actively ingest into kind of a fish.This hair
Bright food training of opening is anaesthetized using anesthetic, with soft plastic dropper that chironomus larvas minced etc. is natural 1 times a week
Bait pours into its stomach, during which continues to feed live fish, ensure that the food-intake of wild blackspot Yuan Select-Committee during opening food, until black
Ban Yuan Select-Committee can be preyed on actively.Blackspot Yuan Select-Committee survival rate is close to 100% in domestication three months.
3, to enable wild blackspot Yuan Select-Committee smoothly to be tamed, select anesthetic for MS-222, MS-222 safety is higher, makes
With in the process not there is a situation where anesthesia it is excessively dead, it is highly-safe.
4, wild blackspot Yuan Select-Committee is lived in rapid limpid river water, and higher to water quality requirement, the present invention is to water temperature, ammonia nitrogen
Concentration, nitrite concentration and pH value have all carried out strict control, using the water body ring for being most suitable for wild blackspot Yuan Select-Committee existence
Border, and water body keeps the salinity of 5-12 ‰, prevents the generation of various nosomycosises, bacterial disease, is further ensured that the health of kind of fish.
5, the present invention is during raising and train, for the saprolegniasis of blackspot Yuan Select-Committee easy infection, corpus luteum disease, ich and liver
Disease actively takes corresponding remedy measures, effectively controls the disease incidence of kind of fish.
