Embodiment

Following embodiment is convenient to understand the present invention better, but does not limit the present invention.Experimental technique in following embodiment, if no special instructions, is conventional method.

embodiment 1

Fish pond of the present invention fish-cultivating method is as follows:

1, reasonable plant-site selection: select traffic convenience, have abundant water resources, connects electricity convenient, the free of contamination place of water source clean hygiene;

2, fish pond is built, and enables water level reach 1.5 meters;

3, lime disinfection: quicklime can produce highly basic (slaked lime) after meeting water, there is very strong sterilizing and kill harmful animal ability, about seed puts first half of the month in a suitable place to breed, fine day is selected to adopt lime disinfection, during sterilization, water need be stayed in fish pond, depth of water 30-50cm, so that the quicklime be sprinkled into can be uniformly distributed, quicklime consumption 75kg/ mu;

4, choose fingerling, choose the healthy fry without desquamation, general Silver Carp, major part silver carp, grass carp put the long fingerling of 10-12cm in a suitable place to breed, and carp puts about 5cm length in a suitable place to breed.It is more moderate that every mu of water surface throws in 500 tails, specifically can grasp flexibly according to the main kind situation breeded fish.Throw in fingerling to carry out when will select fine, must not overcast and rainy or snow, carry out in the weather of blowing, more unsuitablely to throw in freezing sky;

5, fish vaccine is inoculated:

A. select red skin gill rot enteritis triple vaccine, this vaccine can prevent fish bacterium, parasite, viral disease.Vaccine for subsequent use is placed in the cool, and the peg vaccine bottle prepared to be injected all need hide with Sunshade film, and solar control is directly shone, in order to avoid vaccine failure;

B. according to fish body size, the fingerling vaccination of general body weight below 30 grams 0.2 milliliter, the fingerling vaccination of 30-250 gram 0.3 milliliter, the fingerling vaccination of more than 250 grams 0.5 milliliter, or according to the dosage injection that product description is recommended.In order to quick, convenient, usual continuous syringe, after modulation fixes vaccine scale, is injected continuously;

C. injection site: dorsal fin base portion or the intramuscular injection of abdomeinal fin base portion, less than 50 grams fingerlings with dorsal fin base portion injection effect for the best, more than 50 grams fingerlings with abdomeinal fin base portion injection effect for the best;

D. injection depth is advisable with 0.2-0.5 centimetre, does not injure internal organ be in principle as the criterion with vaccine injection fish health, prevents syringe needle from carrying scale secretly and inserts in fish body.Too deeply injure fish body internal organ to prevent entering pin during injection, can overlap one little section of plastic tube on injection needle, the length of needlepoint exposed slightly is longer than fish body abdominal muscle thickness;

E. easily cause the injured or desquamation of fish body in vaccination process, if not treatment of fish body, be easily subject to the invasion and attack of pathogen, especially the invasion and attack of mould, fish body easily suffers from these natural disposition diseases such as saprolegniasis.Therefore, the fish body after injection will take disinfectant measure, and conventional disinfecting drug is salt, potassium permanganate, and saline solution concentration is at 3%-5%, and potassium permanganate concentration is 20 mg/litre.After vaccination, fingerling can be concentrated to put in a suitable place to breed and soak 10-20 minute in thimerosal, note the reaction of fish body in immersion process, prevent the generation of the bad reactions such as anoxic (fingerling should be thrown in immediately into water surface for aquaculture when there is bad reaction), then rendering in breeding water body;

6, aquaculture management: 7-9 month be that cultured fishes are ingested in a large number, between the optimal period that grows fast, be again the epidemic season of fish disease outburst simultaneously, therefore breed in stew should base oneself upon and combat a natural disaster, throws something and feeds and the work such as diseases prevention:

A. strengthen and combat a natural disaster sense of risk: during summer, the phase is concentrated in violent storm, feeding and management person will establish and strengthen anti-risk consciousness, the flood control and water drain canal around inspection fish pond, pool base turnover sluice, poultry column home, prevents uterine bleeding from caving in, find dangerous situation, repairing at once, reinforcing, prevent trouble before it happens;

B. regulating water quality is noted: regulate water body acid-base value with quicklime.In violent storm season during summer, the yellow mud shipwreck that Freshets roar down from the mountains sweeps away is exempted to pour in pond, moreover natural water is all acidic bodies of water, therefore wants regular quicklime regulate water PH value.Generally water full pool spilling head changed by every mu of 1 meter of depth of water quicklime 15 to 20 kilograms, and 15 days once, makes pH value between 7.5 to 8.5.Regular probiotics regulating water quality, conventional microbial ecological preparation has photosynthetic bacteria, bacillus etc.Particularly after long heavy rain, ecological environment of fishpond is inflicted heavy losses on, and even destroys microecological balance.During this time use microbial bacterial in good time, repair Tiny ecosystem circulation, build good fish growth water quality environment particular importance;

C. regularly water is changed in bath: particularly after heavy rain, the water in general fish pond is more muddy, easily worsens, and waist is washed by water in good time and changed water after stabilization, breeding water body is made to keep " fertile, alive, tender, refreshing ", start aerator, air pressure is low in the morning in good time, starts aerator oxygenation when fish will raise the nose above water to breathe, if pool open area is large, drive aerator when for the moment can't resolve floating head problem, oxygenation agent emergency will be added at once, calm down fish and raise the nose above water to breathe dead because of anoxic.

7, preventing and curing of fish disease: summer high temperature is rainy is fish disease eruption and prevalence season, and virus, bacterium, parasite, blue green algae outburst, easily cause the sick death of fish.Generally, regular bleaching powder, fish bacterium are clear etc., and chloride medicine carries out water disinfection kills bacterial virus, parasite and blue green algae (custom is shagreen water) is slaughtered with copper sulphate and mixture of ferrous sulfate (mass ratio is 5:2), water body acid-base value is regulated with quicklime, hemorrhage equality of simultaneously throwing something and feeding takes pharmaceutical chemistry orally, add Chinese herring body healthy growth, improve resistance against diseases.

8, fishing method: dry net, hand are casted net and use, about 10 meters next dry nets of being separated by, then hand is casted net and is driven, if can find bottom sediment heavier scrape net, also can drag with scraping net, catching all in one draft.

Apply the fish culture that method of the present invention carries out fish pond, be calculated to be motility rate: Silver Carp 985 tail, major part silver carp 967 tail, grass carp 958 tail, carp 5695 tail, total quantity tail 8605 tail, the fry of input is 10000 tails, survival rate tail 86.05%, exceeded 16% than conventional 70%, effect is quite remarkable.

Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
