Description
Technical field
The utility model belongs to aquaculture field, and particularly a kind of erythroculter ilishaeformis natural spawning hatches difunctional equipment.
Background technology
Qiao Zui Hong Erythroculter (Erythroculter ilishaeformis), also known as: large whitefish, stick up face, stick up shell, white silk, Qiao Erythroculter etc., classification is subordinate to the fish of Cypriniformes, Cyprinidae, Culter subfamily, red Culter genus.Erythroculter ilishaeformis is carnivorous famous and precious large-scale economic fish, and individual large, growth is fast, and premunition is strong, the pure white delicacy of meat, nutritious, delicious flavour, for top grade in fish, exactly likes Shad fish, eat raw and process all suitable, steamed large whitefish is Chinese famous classic dish, well-known, is well received by consumers.Erythroculter ilishaeformis fry is propagated 2 years artificially and reaches listing specification, wide market.Because erythroculter ilishaeformis wild resource is limited, river,lake and reservior amount of fishing is fewer and feweri, and improving constantly with people's living standard, erythroculter ilishaeformis demand is constantly increased, supply falls short of demand in market, the cultivation accelerating this famous-brand and high-quality kind is promoted, and drive increasing peasant income, market prospects are very good, but because seed lacks, constrain the industrialized development of this famous-brand and high-quality kind, therefore, artificial breeding erythroculter ilishaeformis meaning in enormous quantities is very large.
Erythroculter ilishaeformis is that a kind of wild from numerous property fish, the egg-laying period generally concentrates on first half of the month in the second half of the month in June to July, but also has in advance with time difference or postpone.Under natural environment, after erythroculter ilishaeformis parent population oestruses and lays eggs, fertilized egg just sticks to water plants branches and leaves, chad and swims on the grass blade of the water surface, on stiff mud and grows, ovum microviscosity, in pale yellow grey, ovum footpath 1.0 ~ 1.3mm, fertilized egg meets water just imbibition, when water temperature is in 25 ~ 29 DEG C of amplitudes of fluctuation, approximately only needs 22 hours from fertilization to hatching.The method of current artificial propagation erythroculter ilishaeformis, general employing two kinds of methods, for once producing fry amount at millions of tail, be by injection ocyodinic after parent population put into circuit for four large Chinese carp hatch fish roes, with stimulation by running water, lay eggs in circuit, be fertilized, on the wall that fertilized egg is bonded at circuit and on artificial fish nest, lay eggs after terminating, catch out parent population, fish-egg is hatched in circuit.For small-scale production, be that the parent population of injection ocyodinic is put into the cement pit or net cage that arrange fish nest, stimulate with current, fertilized egg is bonded on fish nest.Caught out by parent population after laying eggs and terminating, fish-egg is sudden and violent gas hatching in net cage.
Major defect in existing method comprises, even if for the production of once producing fry amount and can reach millions of tail, as fertility and the needs of production of large-scale economic fish, this quantity is still less, and existing method hasten parturition after erythroculter ilishaeformis parent population, because individuality is larger, it is more outstanding in narrow and small circular hatching channal mate and oviposit phenomenon of being obstructed, cause spawning rate low, also due to the pool wall finite surface area of circular hatching channal, the fish-egg of microviscosity easily comes off and deposits bottom circuit, causes fertility rate and hatchability low; For small-scale production, general quantity is less, and cost is higher, not at the comparable category of the utility model.For meeting the need of market, lot-sizeization breeding must be relied on and produce.
Utility model content
The purpose of this utility model be for erythroculter ilishaeformis manually there is no in breeding in enormous quantities biological control equipment, the spawning rate of parent population, fish-egg fertility rate and hatchability general lower; and fish for after Gunther parent fish spawning and shift out operation and cause fish-egg to lose the technical problem such as serious; propose a kind of erythroculter ilishaeformis natural spawning and hatch difunctional equipment; make erythroculter ilishaeformis manually in enormous quantities breeding have suitable equipment and the propagation method in enormous quantities that matches, significantly improve the fertility rate and hatchability of spawning rate that erythroculter ilishaeformis breeds in enormous quantities, fish-egg.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
