Present invention is disclosed a kind of breeding method of grass carp winter sheet fingerling, this breeding method is by adopting manual injection's grass carp vaccine and using microbe preparation regulating water quality, not only improve breeding environment, decrease disease fish to occur, and achieve the high yield of grass carp winter sheet fingerling, achieve very significant culture benefit.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the process figure of embodiment of the present invention grass carp winter sheet fingerling cultivating method.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Fig. 1 is the process figure of embodiment of the present invention grass carp winter sheet fingerling cultivating method; This breeding method comprises the steps: water quality of a) cleaning up the pond and foster and apply fertilizer, and b) puts Young grass carp fry in a suitable place to breed, c) manual injection grass carp vaccine, and d) science is thrown something and fed feed, e) using microbe preparation regulating water quality, f) daily management.
The breeding method of the grass carp winter sheet fingerling that the present invention mentions is on the basis of traditional breeding way, to be thrown something and fed feed by manual injection grass carp vaccine, using microbe preparation and science, greatly reduce disease incidence and the lethality of grass carp winter sheet fingerling, achieve higher output and economic benefit.Wherein, manual injection grass carp vaccine considerably reduces grass carp disease, particularly prevents the generation of hemorrhage preferably, ensure that the survival rate that Grass Carp Juveniles is higher.The use of microorganism formulation is more convenient, and the sewage environmental pollution of its discharge is little, and simultaneously to the regulating action Be very effective of water quality, water quality adjustment has been got well, and disease naturally-occurring must be lacked, and efficiency of feed utilization also improves, thus adds the economic benefit of cultivation.
Embodiment
Concrete breeding method is as follows:
A) to clean up the pond and water quality of fostering and apply fertilizer, clean up the pond and select to carry out in mid-April, first remove too much mud with giant and sludge pump, make mud maintenance about 15cm thick, then tan by the sun 15d at the bottom of pond after being drained by Chi Shui, then use 75kg/667m
2quicklime be watered rear full pool spilling head sterilization.Water quality of fostering and apply fertilizer is selected to carry out after the 4d that cleans up the pond, and new water of first annotating to pond, executes microbial manure 5kg/667m to depth of water 60cm, 7d
2with chlorella vulgaris 500mL/667m
2, pond water planting is bred as glossy dark green mulberry, makes water keep tender, refreshing.
B) put Young grass carp fry in a suitable place to breed, put Young grass carp fry in a suitable place to breed and select to carry out at the end of May, put front 2d in a suitable place to breed first by 100g/667m
2the former powder of consumption full pool spilling head EM bacterium, to strengthen Grass carps' fries immunity, again the Young grass carp fry of long for preferred body more than 5cm is soaked 10min with 5% saline solution to carry out disinfection, then manual injection grass carp vaccine is carried out to Young grass carp fry, afterwards by 25000 tails/667m
2breeding density is put in a suitable place to breed.
C) manual injection grass carp vaccine, manual injection grass carp vaccine carries out when throwing in Young grass carp fry, to prevent the generation of hemorrhage.Instrument used for injection adopts continuous syringe and No. 4 syringe needles of 0.5L, and syringe needle base portion overlaps one section of rubber tube; In injection process, injection depth is 0.2cm, and syringe needle and fish body are 30 ° of angles, and dorsal fin is injected, and injected dose is 0.1mL.
D) science is thrown something and fed feed, first enters full pool spilling head soya-bean milk in the 7d of pond Young grass carp fry, and every day is early, evening respectively throws something and feeds 1 time, day feeding volume be 3kg/667m
2; Then protein content of throwing something and feeding is the compound feed of 30%, and every day is early, middle and late respectively throws something and feeds 1 time, day feeding volume be 5kg/667m
2, first grass carp is carried out to the tame and docile food training of about 10d when throwing something and feeding, uses device for feeding fish bait fixed point afterwards instead and to throw something and feed compound feed.
E) using microbe preparation regulating water quality, using microbe preparation regulating water quality can improve the generation of breeding environment and prevention fish disease.Embody rule process is: in 6 ~ August every 15d by 100g/667m
2the former powder of consumption full pool spilling head photosynthetic bacteria; 100g/667m is pressed every 15d in 9 ~ December
2the former powder of consumption full pool spilling head composite bacillus.The former powder of photosynthetic bacteria and the former powder of composite bacillus in use, are first converted brown sugar activation 4h with former pond water, then are carried out full pool spilling head, to strengthen result of use.
F) daily management, daily management comprises: sooner or later patrol the pool every day twice, the new water of filling and change water, open aerator in good time, regularly to splash Avermectin and chlorine dioxide in good time.Wherein, new water of annotating carries out once every 5d, adds about 10cm at every turn; Change water to carry out once every 30d, change water about 30% at every turn.The unlatching of aerator, fine day is arranged in start at noon, and overcast and rainy being arranged in is started shooting evening, keeps pond waters dissolved oxygen at more than 4.5mg/L.The use of Avermectin is splashed 1 time every 20d, carries out desinsection, and 1 chlorine dioxide of splashing again every other day carries out sterilizing.
