Description

A kind of cultural method of the naked abdomen biological feed for aquaculture
Technical field
The present invention relates to the cultural method of a kind of naked abdomen biological feed for aquaculture, belong to biological technical field.
Background technology
In the seed rearing of aquaculture, the biological feed after wheel animalcule that nature finds has artemia larvae, Copepods and cladocera (i.e. naked abdomen).Artemia larvae (is formed by artemia ovum hatching) because resource is day by day rare, and price rises violently year by year, and there is the pathogenic bacteria pollutions such as vibrio;Though Copepods, cladocera have abundant nutrition with microalgae for bait, but fish for by natural water area and limited by season, weather etc., originate very unstable.So relying on sufficient microalgae biological, become the dream of culture fishery indoor high-density cultivation Copepods and cladocera in conjunction with prebiotic mushroom.
Naked abdomen (Moinamacrocopa), also known as cladocera, belongs to invertebrates, and the long 0.2-l.0mm of body, majority is grown in freshwater, lake, rivers, is the important bait of Fish, therefore is commonly called as " worm for fishing ".The wide adaptability of naked abdomen, reproductive capacity is strong, and growth rapidly, and is of high nutritive value, and is the agreeable to the taste bait in aquaculture larval rearing stage.Naked abdomen indoor high-density is cultivated, overcome the defect such as field nature growing environment living contaminants, growth instability, product production capacity is high, nutrition is agreeable to the taste, clean is the excellent substitute of artemia larvae without dirty, easy to use, is the optimal biological open-mouthed bait of following culture fishery.
Summary of the invention
In view of background technology Problems existing, the present invention provides the cultural method of a kind of naked abdomen biological feed for aquaculture, its can turn out have that toxigenic capacity is low, be of high nutritive value, biological feed that palatability is strong, pollution-free, easy to use.
In order to realize the purpose of the present invention, the present invention provides the cultural method of a kind of naked abdomen biological feed for aquaculture, this cultural method includes step: joined by tap water in breeding pond and culture pond, temperature regulates to 25-30 DEG C, and passing into compression air, ventilation is advisable with the unhurried current forming water body 3-5cm/s;Chlorella pyrenoidesa concentrated solution and EM bacterium solution are put in bait tin according to the ratio that volume ratio is 1:1, at the temperature of 25-30 DEG C, passes into the air-activated 24-48h of compression, form the mixed feed of naked abdomen;Being joined by mixed feed in breeding pond, addition is the 1-5 ‰ cultivating Water quality;Being put into by the seedling of naked abdomen in breeding pond, input amount is the 1-3 ‰ of breeding pond Water quality, and adds mixed feed to the relaying afterflow of breeding pond;After the naked abdomen in breeding pond cultivates 48-72h, rendering in culture pond by culture fluid together with naked abdomen, culture pond temperature keeps 25-30 DEG C;When abdomen naked in culture pond is cultivate Water quality more than 10 ‰, naked abdomen polypide and culture fluid are discharged from the overfall of culture pond.
By above technical scheme, beneficial effects of the present invention is as follows: have compared with the tradition bait such as artemia larvae that toxigenic capacity is low, be of high nutritive value, palatability is strong, the feature such as pollution-free, easy to use, is the optimal biological open-mouthed bait of following culture fishery.
Detailed description of the invention
Below in conjunction with embodiment, the specific embodiment of the present invention is further described, advantages of the present invention and feature will be with describe and apparent.But these embodiments are only exemplary, the scope of the present invention is not constituted any restriction.
The present invention provides the cultural method of a kind of naked abdomen biological feed for aquaculture, this cultural method includes step: joined by tap water in breeding pond and culture pond, temperature regulates to 25-30 DEG C, and passes into compression air, and ventilation is advisable with the unhurried current forming water body 3-5cm/s;Chlorella pyrenoidesa concentrated solution and EM bacterium solution are put in bait tin according to the ratio that volume ratio is 1:1, at the temperature of 25-30 DEG C, passes into the air-activated 24-48h of compression, form the mixed feed of naked abdomen;Being joined by mixed feed in breeding pond, addition is the 1-5 ‰ cultivating Water quality;Being put into by the seedling of naked abdomen in breeding pond, input amount is the 1-3 ‰ of breeding pond Water quality, and continuously adds mixed feed in breeding pond;After the naked abdomen in breeding pond cultivates 48-72h, rendering in culture pond by culture fluid together with naked abdomen, culture pond temperature keeps 25-30 DEG C;When abdomen naked in culture pond is cultivate Water quality more than 10 ‰, naked abdomen polypide and culture fluid are discharged from the overfall of culture pond.
Wherein, EM bacterium solution includes bacillus subtilis, photosynthetic bacteria and schizochytrium limacinum.
Wherein, the PH of culture fluid is 6.5-8.0.
Wherein further comprise the steps of:
The naked abdomen polypide that overfall is discharged is through the sieves of 80-100 order;The naked abdomen filtered out, after tap water embathes, is filled in plastic bag, lies in refrigerator tray with the thickness of 1-2cm, then IQF, and quick freezing temperature controls below-30 DEG C;The naked abdomen polypide vanning freezed is deposited, and storage temperature is subzero 15-20 DEG C.
The culture fluid being filtrated to get returns culture pond cycle after foam separator purified treatment and uses.
Inventionculture tools and facility
Cultivating utensil: naked abdomen High Density Cultivation uses breeding pond and two kinds of containers of large-scale culture pond, breeding pond adopts acrylic water vat, for cultivation and the amplification of naked abdomen seedling, is generally 1-2m3;Culture pond adopts cement pit, cultivates for industrialization, and volume is 10-20m3
Cultivate water body: concrete water level is determined depending on naked abdomen seedling quantity, can be controlled between the 30-40% of capacity in advance, be added gradually to that pond is deep afterwards 80%.
