Abstract
The invention discloses a specific-pathogen-free living bait for aquatic-seedling culture. The specific-pathogen-free living bait is prepared by mixing one or more of chlorella, rotifera, fairy shrimp, larvae, copepoda, artemia and clam worm, cleaning, packaging, freezing and forming. The specific-pathogen-free living bait is characterized in that the formed bait is disinfected by a radiation manner. The specific-pathogen-free living bait disclosed by the invention adopts the radiation manner to disinfect the living bait for the aquatic-seedling culture, has the advantages of benefit for aquatic larvae, easy use, convenient operation, though disinfection and reduction of feeding cost and is higher in innovation.
Description
Technical field
The invention belongs to aquatic feed field, particularly a kind of specific pathogen free aquatic fry growing biological feed.
Background technology
Along with the development of mariculture industry, in economy aquatic animals nursery produces, biological feed increasingly plays important role.Biological feed not only size is agreeable to the taste, facilitates Aquatic product germling to ingest, and nutritious, it is easy to digested.
In the prior art, Aquatic product germling derives from artificial cultivation at the biological feed that nursery stage is ingested or fishes in natural water, the freezing processing completing fresh and alive or freezing biological feed again after cleaning or cleaning.
But, any cultivation or the biological feed fished for, all contain a large amount of antibacterial after cleaned processing, growth and survival to Aquatic product germling cause great threat, make aquatic fry growing success rate and survival rate low.At present, the method that biological feed is carried out disinfection adopts hydrogen peroxide or this simple method of formaldehyde to process mostly, there is following drawback in this method: 1. sterilization is not thorough, ozone or formaldehyde sterilization, the cause of disease of biological feed body surface can only be eliminated, and the cause of disease in bait body can not be eliminated, after sterilization, still pathogen can be brought in seedling water, the survival of Aquatic product germling is threatened；2. the biological feed of ozone or formaldehyde treated, it is necessary to clean especially, to eliminate residual, if cleaning not thorough, Aquatic product germling also can be damaged by residue, and then affects the survival of germling.
In order to ensure survival rate and the quality of Aquatic product germling, need the biological feed after sterilization is detected, and specific pathogen, such as vibrio flavus, green vibrio, vibrio niger, photobacteria, WSSV (guttate morphea syndrome), IHHNV (prawn infectious subcutaneous and haematopoietic necrosis virus), HPV (prawn hepatopancreatic parvovirus), YHV (prawn yellow head virus), TSV (prawn Fructus Persicae draws syndrome), EHP (shrimp liver sausage spore worm), VPAHPND(Acute Hepatic pancreatic necrosis pathogenic vibrio) cause of disease, is the encountered pathogenic of biological feed, is also the emphasis of detection.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of be conducive to Aquatic product germling, be easily achieved, conveniently operate, the production method of the specific pathogen free aquatic fry growing biological feed thoroughly of sterilizing.
This invention address that its technical problem is achieved through the following technical solutions:
A kind of specific pathogen free aquatic fry growing biological feed, this biological feed is mixed by one or several arbitrary proportion of chlorella, wheel animalcule, halogen children, Copepods, artemia, clam worm, cleaned, packaging, freezing postforming, it is characterised in that: the bait after shaping is sterilized by the mode of irradiation.
And, described irradiation sterilization is for utilizing gamma-ray irradiation sterilization or x-ray irradiation sterilization or electron beam sterilization.
And, the irradiation metering of described irradiation sterilization is 1-20kGy.
And, described irradiation sterilization method is applied in the production of specific pathogen free aquatic fry growing biological feed.
Advantages of the present invention and having the beneficial effect that
1, this specific pathogen free aquatic fry growing biological feed, by utilizing the mode of irradiation sterilization to remove the specific pathogen in bait, the method is safe and reliable, and sterilization thoroughly, is conducive to survival and the growth of Aquatic product germling.After irradiation sterilization, biological feed is without aquatic fry growing specific pathogen, for the aquatic fry growing biological feed of specific pathogen free, makes the biological safety of aquatic fry growing industry be greatly improved.
2, the sterilization method of this specific pathogen free aquatic fry growing biological feed is easy to operate, through the biological feed of radiation treatment, before use, it is not necessary to carry out any cleaning again, disinfect, use very simple, also save the costs such as substantial amounts of human and material resources.
3, the sterilization method of this specific pathogen free aquatic fry growing biological feed makes nursery success rate and survival rate be greatly improved, aquatic fry growing uses the biological feed of radiation treatment, will not again pathogen be introduced in seedling water, the threat of nursery is significantly reduced by disease, the success rate of aquatic fry growing improves, and the survival rate of nursery also improves.
4, design science of the present invention is reasonable, have be conducive to Aquatic product germling, be prone to use, convenient operation, sterilization thoroughly, reduce the advantage of cost of throwing something and feeding, be a kind of specific pathogen free aquatic fry growing biological feed with higher innovation.

Detailed description of the invention
Below by specific embodiment, the invention will be further described, and following example are illustrative, is not determinate, it is impossible to limit protection scope of the present invention with this.
A kind of specific pathogen free aquatic fry growing biological feed, Copepods in water body is acquired, then the Copepods gathered is sequentially carried out cleaning, fill, freezing and packaging, and its innovation is in that: the frozen goods after packaging are carried out gamma-ray irradiation process, and irradiation metering is 6kGy.
Detecting through relevant departments, the biological feed of the present invention does not contain vibrio flavus, green vibrio, vibrio niger, photobacteria and WSSV, IHHNV, HPV, YHV, TSV, EHP, VPAHPND。
Examining report, is shown in Figure of description.
Although disclosing embodiments of the invention and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope without departing from the present invention and claims, various replacements, to change and modifications be all possible, therefore, the scope of the present invention is not limited to embodiment and accompanying drawing disclosure of that.
