Description
Technical field
The utility model relates to prawn culturing technical field, especially a kind of prawn family selective breeding device based on net cage.
Background technology
Environment of Litopenaeus vannamei Low (
litopenaeusvannamei), also claim Penaeus Vannmei, belong to Arthropoda (Athropoda), Crustachia (Crustacean), Decapoda (Decapoda), natural distribution is in Peru to Mexican pacific rim.Because it has the features such as wide adaptability, resistance against diseases is strong, fast growth, dietary protein level demand are low, promoted widely and cultivate, having become is one of global topmost prawn culturing kind.But increase along with cultivation algebraically and breeding environment worsens, the advantages such as its cycle is short, fast growth, feed coefficient are low and resistance against diseases is strong more not significantly, are therefore carried out genetic improvement to Environment of Litopenaeus vannamei Low kind and are seemed especially important.
Family selective breeding is one of important method obtaining improved seeds, and the selection and use of Environment of Litopenaeus vannamei Low extensively adopts the method for families selecting.In the extensive family selective breeding process of Environment of Litopenaeus vannamei Low, different family prawn individuality need be put into same environment and cultivate, carry out the comparison of the economic characters such as growth, survival rate between family.Owing to needing to distinguish different familys in same environment, therefore need to mark each family, the conventional labeling method of current shrimps family is fluorochrome mark, not only cost high, expend more manpower and materials, often cause mark prawn death, and in the breeding process in mark later stage, the mark capacity of some individualities thickens and even loses, thus affects breeding value forecasting accuracy, and then the accuracy of impact selection, reduction genetic progress and selection are reacted.
Summary of the invention
The purpose of this utility model is the deficiency overcoming above-mentioned prior art, provides the accurate evaluation that a kind of structure is simple, practical, cost is low, be beneficial to genetic parameter, improves the prawn family selective breeding device based on net cage of seed selection accuracy.
To achieve these goals, the technical solution adopted in the utility model is: a kind of prawn family selective breeding device based on net cage, it is characterized in that: comprise oval culturing pool, fish culture net cage, material-feeding platform and aerating device, oval culturing pool pool side is provided with water inlet pipe, two sides waterwall is provided with in the centre of oval culturing pool, mudhole is offered at the bottom of pond between the waterwall of two sides, mudhole is connected with a blow-off pipe, fish culture net cage is provided with multiple and arranges along oval culturing pool pool side, each fish culture net cage is provided with a material-feeding platform and a nameplate, an aerating device is provided with between every two adjacent fish culture net cages, aerating device comprises air pump, gas tube, gas charging stone and PVC semicircular plate, PVC semicircular plate offers manhole, gas tube one end is connected with air pump, the other end is connected with gas charging stone through the manhole on PVC semicircular plate, PVC semicircular plate oblique cutting is in oval culturing pool.
Further, described fish culture net cage comprises the casing be arranged on described oval culturing pool pool side and the bolting silk net surrounding tank floor and side.The mesh of bolting silk net can be selected according to actual needs, is specifically as follows 10-60 order, namely according to the size of the growth adjustment mesh of prawn, increases the permeability of current.
Further, angle at the bottom of described PVC semicircular plate and oval culturing pool pond is 60 °-80 °.
The beneficial effects of the utility model are: structure is simple, practical, cost is low.Adopt above-mentioned seed selection device, by water inlet pipe and aerating device, Chi Shui can be kept slowly to flow, simulate the natural animation of prawn, prawn adaptability is good; And different family prawn is marked by nameplate with different cage culture respectively, and family mark rate and discrimination are 100%; Make each family be in identical breeding environment and reduce prawn family common environmental effect, be beneficial to family Genetic Evaluation; Seed selection accuracy and output capacity can be improved.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of aerating device in the utility model.
Embodiment
As shown in Figure 1, 2, a kind of prawn family selective breeding device based on net cage of the utility model, comprise oval culturing pool 1, fish culture net cage 2, material-feeding platform 3 and aerating device 4, oval culturing pool 1 pool side is provided with water inlet pipe 11, two sides waterwall 12 is provided with in the centre of oval culturing pool 1, offer mudhole 13 at the bottom of pond between two sides waterwall 12, mudhole 13 is connected with a blow-off pipe.
Above-mentioned fish culture net cage 2 is provided with multiple and arranges along oval culturing pool 1 pool side, and each fish culture net cage is provided with a material-feeding platform 3 and a nameplate 5, is provided with an aerating device 4 between every two adjacent fish culture net cages 2.Aerating device 4 comprises air pump 41, gas tube 42, gas charging stone 43 and PVC semicircular plate 44, PVC semicircular plate 44 offers the manhole 45 of 2-3cm, gas tube 42 one end is connected with air pump 41, the other end is connected with gas charging stone 43 through the manhole 45 on PVC semicircular plate 44, PVC semicircular plate 44 oblique cutting is in oval culturing pool 1, and the putting towards being all consistent of each PVC semicircular plate 44.Specifically, PVC semicircular plate 44 tilts to the direction of current, and gas charging stone 43 is in the bottom of PVC semicircular plate 44, and during inflation, gas can promote current direction direction flowing.
