Abstract

The utility model relates to an epinephelus septemfasciatus culturing and spawning pond, which comprises a water pond, a net cage, a PVC (Polyvinyl Chloride) pipeline a and a PVC pipeline b, wherein a reinforcing mesh is fixed in the water pond; the water pond is divided into an upper part and a lower part; the upper part is cylindrical; the lower part is semicircular; the upper part of the water pond is provided with the PVC pipeline a; the PVC pipeline a is horizontally suspended on the water surface of the water pond through a rope; the bottom of the water pond is provided with the PVC pipeline b; the PVC pipeline b horizontally extends out of the water pond through the bottom and then is upwardly provided with another PVC pipeline b through an elbow; and the net cage is arranged outside the water pond and is positioned below the PVC pipeline a. According to the epinephelus septemfasciatus culturing and spawning pond, spawns can be collected well, sewage can be removed, and manpower and material resources can be saved.

Description

A kind of seven band groupers are cultivated and spawning pond

Technical field

The utility model relates to a kind of seven band groupers and cultivates and spawning pond.

Background technology

In seven band grouper (E.septemfasciantus Thunberg, 1973) the parent fish rearing processes, require water level high; Culture the degree of depth at ordinary times more than 2 meters, require to culture the pond diameter more than 8m, the domestic most fish of culturing of the different fishes of these characteristics; Domestic majority industrial aquaculture fish require water level lower, such as just enough about turbot 30cm; The pond diameter about 6 meters all can, so its this specific (special) requirements can not be satisfied in domestic big various breed pond.After seven band grouper parent populations were cultivated and reach sexual maturity, milter chased raun in culture pond, stimulate raun to lay eggs; Milter is discharged seminal fluid then, accomplishes fertilization process, the ovum buoyant egg of fertilization; Swim in the water surface, the pond is big and dark, and manual work is fished for and dragged the method for getting all is worthless.

The utility model content

The purpose of the utility model provides a kind of seven band groupers and cultivates and spawning pond, to overcome the deficiency of prior art.

The purpose of the utility model is to realize through following technical scheme:

A kind of seven band groupers are cultivated and spawning pond, comprise pond and net cage, also comprise pvc pipe road a and pvc pipe road b; Said pond internal reinforcement has bar-mat reinforcement, and said pond is divided into the upper and lower, and being shaped as of top is cylindrical; The bottom be shaped as semicircle, the top in said pond is equipped with said pvc pipe road a, said pvc pipe road a is suspended on the water surface in said pond through the rope level; The bottom in said pond is equipped with said pvc pipe road b, and said pvc pipe road b reaches the outside in pond through bottom level, through elbow said pvc pipe road b is installed upwards again; Said net cage is installed on the outside in said pond, is positioned at the bottom of said pvc pipe road a;

Canvas bucket is placed in the outside of said net cage, and the order number of said net cage is the 50-100 order;

The distance of the upper edge in said pvc pipe road a and said pond is 0-1m, and the length of said pvc pipe road a is identical with the length of the radius in said pond, and said pvc pipe road a is positioned at the inner part in said pond and is open semicircle pipeline;

Said pvc pipe road b is drilled with aperture above being positioned at the inner part in said pond, and the height that upwards is installed on the part on the elbow is equal with the height of the water surface of inside, said pond.

The described a kind of seven band groupers of the utility model cultivate and the beneficial effect of spawning pond is: the fertilized egg of seven band groupers is a buoyant egg, swims on the water surface, and pvc pipe road a is positioned at the inner part in said pond and is open semicircle pipeline again; Can be in face of water (flow) direction, through out-of-date, from then on overflow goes out outside the pond in the pipeline in the fertilized egg that suspends; Flow in the net cage and collect; And need not artificially collect, also can get rid of the dirt that swims in the water surface, reduce manpower and materials; The outside canvas bucket of placing of net cage keeps certain water level, reduce fertilized egg when collecting since the height of water for the influence of fertilized egg; Be drilled with aperture above being positioned at the inner pvc pipe road b in pond, when getting rid of dirt, can prevent the escape of fish; The pvc pipe road b that makes progress that is installed on the elbow can form current through the dial-out of short time in the pond, get rid of the dirt that sinks to the bottom of central authorities.

Description of drawings

Fig. 1 is the overall schematic of described seven band groupers cultivations of the utility model embodiment and spawning pond.

Among the figure:

1, pond; 2, net cage; 3, pvc pipe road a; 4, pvc pipe road b; 5, elbow; 6 canvas buckets.

Embodiment

As shown in Figure 1, the described a kind of seven band groupers of the utility model embodiment are cultivated and spawning pond, comprise pond 1 and net cage 2; Also comprise pvc pipe road a3 and pvc pipe road b4, said pond 1 internal reinforcement has bar-mat reinforcement, and said pond 1 is divided into the upper and lower; Being shaped as of top is cylindrical, the bottom be shaped as semicircle, the top in said pond 1 is equipped with said pvc pipe road a3; Said pvc pipe road a3 is suspended on the water surface in said pond 1 through the rope level; The bottom in said pond 1 is equipped with said pvc pipe road b4, and said pvc pipe road b4 reaches the outside in pond 1 through bottom level, through elbow 5 said pvc pipe road b4 is installed upwards again; Said net cage 2 is installed on the outside in said pond 1, is positioned at the bottom of said pvc pipe road a3; Canvas bucket 6 is placed in the outside of said net cage 2, and the order number of said net cage 2 is the 50-100 order; The distance of the upper edge in said pvc pipe road a3 and said pond 1 is 0-1m, and the length of said pvc pipe road a3 is identical with the length of the radius in said pond 1, and said pvc pipe road a3 is positioned at said pond 1 an inner part and is open semicircle pipeline; Said pvc pipe road b4 is drilled with aperture above being positioned at the inner part in said pond 1, and the height that upwards is installed on the part on the elbow 5 is equal with the height of the water surface of 1 inside, said pond.

During use, after parent population lays eggs, utilize ovum to float on the characteristics of the water surface; At first add water along a direction, make pond 1 inner water form current, the semicircle pipeline of the opening of pvc pipe road a3 is in face of water (flow) direction; Because the effect of outside control water level, a part of current can be flowed out by a3 along the pvc pipe road just, ovum flows among the preset net cage 2 with current; Reach the purpose of receiving ovum, in the pond, make current equally, the upper strata floating pollutant also can be discharged the outside in pond 1 with current through pvc pipe road a3; Sink to the bottom dirt at the bottom of 1 pond, pond; Can pull out the method that the outside is installed on the pvc pipe road b4 on the elbow 5 through the short time, form current, dirt is along with current are discharged through the aperture on the pvc pipe road b4 of 1 inside, pond.
