Abstract
The utility model relates to an incubation apparatus for prawn larva comprising an incubation tank, an incubation tank cover, a lighting apparatus, and a collecting and washing apparatus. The incubation tank and the incubation tank cover are integrated as a whole, and the incubation tank cover is provided with light transmission holes and air-filling tubes connected with micro-hole plugs; the lighting apparatus is located above the light transmission holes. By taking advantage of phototaxy of the prawns, the prawn larva with high vigor and vitality is picked up while the weak prawn larva with poor vitality or dead eggs are wiped out. In this way, high quality larva is collected, which greatly guarantees the survival rate for the larva. The incubation apparatus of the utility model is capable of collecting larva from a plurality of incubation tanks at the same time, thereby saving time and manual work. Simple in structure, the incubation apparatus of the utility model is also practical and effective.
Description
Technical field
The utility model belongs to the aquaculture of aquatic animal technical field, and is particularly a kind of to shrimps young hatching apparatus.
Background technology
Shrimp culture is one of of paramount importance industry in China's culture fishery, and for example: Penaeus Vannmei, Penaeus monodon, japonicus, penaeus penicillatus etc., wherein Penaeus Vannmei is cultured has become one of pillar industry of mariculture industry.Development through decades, although China's shrimp culture has obtained proud economic performance, but people recognize that gradually whether the germplasm of culturing excellent performance is arranged is the key that guarantees the stable development of shrimp culture industry, therefore improve shrimps seed selection correlation technique link, carrying out the shrimps breed breeding is the effective measures of dealing with problems.In prawn family selective breeding process, can obtain the high-quality family young be one of key of carrying out smoothly family selective breeding, traditional family young hatching and the method for collecting are the female shrimp of mating to be put into an incubation vessel that fills the suitable size of hatching water lay eggs, fertilized egg is after hatching under the suitable incubation condition, dredger with 250～300 meshes is pulled the young out, carries out family and grows seedlings.The shortcoming of this way is to checkmate the weak young of ovum, vigor and the energetic young separately, thereby cause the technical staff to entering the erroneous judgement of the link family young number of growing seedlings on the one hand, influence family and set up the standardization requirement of cultivating young number in the process, the decomposition of the young that dead on the other hand ovum and vigor are weak will directly cause the growing seedlings deterioration of water quality influences the growth and the survival rate of shrimp seedling.So, 200720151744.9) and " a kind of hatching apparatus at shrimps, fish or the crab class young " (application number: 200920052830.3) etc. of Zhongshan University's invention someone has invented the hatching apparatus of the prawn young, as " the good year shrimp ovum incubator " of: gold-tinted brightness and the invention of Huanghai Sea dragon (application number:.
Yet, the inventor finds, above patent can be checkmated the ovum and the young separately substantially, but also there is certain shortcoming, be that present technology still can not be distinguished the weak young of vigor and the energetic young, so can only with physique more weak mix breed with the good young of physique, had a strong impact on the quality of shrimp seedling.Therefore, developing the method that the young a little less than the energetic high-quality young and dead ovum and the vigor is effectively separated, is that the family link of growing seedlings guarantees to cultivate the key of young number of criteria requirement, is to improve shrimp seedling quality, set up the prerequisite of family smoothly.
Summary of the invention
The purpose of this utility model is the defective that overcomes prior art, provide that a kind of efficient, simple, practical ovum of the energetic high-quality young being collected and checkmate separates with the weak young of vigor to shrimps young hatching apparatus.
The technical solution of the utility model is:
To shrimps young hatching apparatus, comprise hatching apparatus, lighting device, collect wash mill, be characterized in: described hatching apparatus comprises hatching pail and hatching bung, hatching pail and hatching bung are formed one, hatching pail covers the gas tube that is provided with loophole and is connected with the micropore plug, lighting device is placed on the top of loophole, described collection wash mill comprises the collection washing disk, siphon pipe and collection seedling net, this is to adopt illumination to form the method for hot spot to shrimps young hatching apparatus, utilizes the phototaxis of prawn to select the energetic shrimps young and remove the weak shrimps young of vigor and dead ovum.
Above-described hatching apparatus, hatching pail and hatching bung are made by nontoxic opaque material.
Above-described micropore is gas stone or foraminate plastics, Sponge.
Above-described lighting device comprises lampshade and electricity-saving lamp.
The beneficial effects of the utility model are:
Compared with prior art, of the present utility model have following outstanding feature to shrimps young hatching apparatus: the hatching apparatus that utilizes opaque material to make, can be effectively the young and dead ovum a little less than the energetic young and the vigor be separated, be convenient to the collection of the high-quality young, survival rate of seedling improves greatly, the utility model can also collect seedling simultaneously to a plurality of hatching pails, thereby saves time and artificial, simple, practicality, effective.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described shrimps young hatching apparatus.
As Fig. 1, Fig. 3, shown in Figure 4, shrimps young hatching apparatus is comprised hatching pail 1, hatching bung 2, lighting device 3, gas tube 4, collects wash mill 6, loophole 7 and air-vent 8, hatching pail 1 and hatching bung 2 are made by nontoxic opaque material and are formed one, hatching bung 2 is provided with loophole 7 and air-vent 8, the gas tube 4 that is connected with the micropore plug is installed on the air-vent 8 of hatching bung 2, lighting device 3 is positioned over loophole 7 tops of hatching bung 2, and described lighting device 3 comprises lampshade and electricity-saving lamp.
As Fig. 2, Fig. 5, shown in Figure 6, collect wash mill 6 and comprise collection washing disk 9, siphon pipe 5 and collection seedling net 10.
Operation principle of the present utility model is as follows: the shrimps nauplius has phototaxis, and the vigor of the strong more young of phototaxis is strong more, and dead ovum easily is sunken to the bottom.The utility model by designed hatching apparatus owing to be opaque material, so only unique hot spot that the loophole 7 on lighting device 3 and the hatching bung 2 is made at hatching pail 1 water surface, utilize the phototactic biology characteristics of the shrimps young, the energetic young is concentrated on the hot spot place, thereby will sink to the dead ovum at the bottom of the hatching pail and phototaxis is poor, move slowly that the young effectively separates, guarantee to collect the high-quality young.
