Description

Intensive pond fish farming small net cage

The utility model relates to fish farming equipment and equipment.

At present, most of the fish farming adopts the whole pond to raise one kind of fish or several kinds of fish with different living habits; fish.

In view of the net cages used on large waters are all positioned with floating frames and sinkers, a material table is provided in the net cage and bait is supplied by a bait throwing machine; an aerator is arranged in the center of the net cage. This kind of fish culture net cage has the advantages of high bait utilization rate and high output per unit area; however, due to the limitation of structure and size, this large net cage cannot be effectively used in small pools, narrow waterways and river bays, etc. In particular, the species of farmed fish is relatively single, and it is difficult to adapt to the changing market demand; in addition, this kind of cage is only suitable for the cultivation of adult fish and commercial fish, and cannot be used for breeding from broodstock to spawning and hatching of fish species.

The main purpose of this utility model is to design and provide a small net cage for fish culture in an intensive culture pond and its matching equipment, so that it is suitable for fish culture in waters with different areas. According to market needs, several net cages in a pool Several different kinds of fish are bred in the box, and can be engaged in a series of factory-style breeding from broodstock to water flower and fish spawn hatching, forming a serialized and diversified production line.

In order to achieve the above object, the utility model adopts the following design scheme:

The small net cage for fish culture in the intensive culture pond of the present utility model includes a small net cage for fish culture and supporting equipment; The mesh constitutes and forms a net cage with an open top, and a tether is provided on the skeleton, and a connecting hook can be provided on the tether, and a feeding platform and 1 to 3 oxygen-increasing pipes can be connected to the bottom net surface. Oxygen carbon head; the supporting equipment includes a small net cage fixed frame, aerator, aeration pipeline and pump, and the fixed frame is composed of a column vertically fixed at the bottom of the pool, a horizontal longitudinal beam or/and a crossbeam erected on the top of the column, The distance between the longitudinal beams and the beams is equivalent to the vertical and horizontal dimensions of the small cages. Several evenly arranged vertical connecting columns are arranged on the longitudinal beams or beams, and a pulley or several connecting columns of different heights are arranged on the connecting columns. ring; the oxygenation pipeline is laid on the side lower part of the longitudinal beam or/and the crossbeam and is respectively connected with the oxygenation machine and the oxygenation carbon head. The small net box is connected with the pulley or the connecting ring on the frame connecting column through the rope or the connecting hook on it.

The size of the small net cage is 2.5 to 3.5 in length, 2.5 to 3.5 in width, and 2 to 3 meters in depth; the mesh of the small net cage for cultivating black cubs is 40 to 60 mesh, and the mesh of the mesh cage for cultivating the parent is 1.5 cm. .

For a clearer understanding of the rationality and advantages of the design of the present utility model, it is described as follows in conjunction with the embodiments and accompanying drawings:

Figure 1—Schematic diagram of the structure of the small cage.

Figure 2—Schematic diagram of the fixed frame structure of the small cage.

Fig. 3 - the connection schematic diagram of small net cage and fixed frame.

This small net cage (referring to Fig. 1) is, by 4～8 vertical rods 1.1,4～6 longitudinal horizontal rods 1.2,4～6 horizontal horizontal rods 1.3 linking cuboid skeleton, and 5 fixed Mesh sheets 1.4, 1.5, 1.6, 1.7, and 1.8 are formed at the front, back, left, right, and bottom of the skeleton; the ropes provided on the top of the 4 vertical rods or the connecting hooks 1.9 that are softly connected are connected with the fixed frame connecting column 2.4 The bone wheel or the connecting ring 2.5 are connected, so the small net cage can be adjusted in height to adapt to different water levels and temperatures. The columns 2.1, horizontal beams 2.2, and horizontal longitudinal beams 2.3 that constitute the fixed frame of the small net cage are all orthogonal to each other, and their size matches the small net cage, so they are neatly arranged and can make full use of the water surface. The aeration pipeline 3.1 connected with the aerator is horizontally arranged on the side lower part of the beam or the longitudinal beam, so it does not hinder the fish farming operation. Under the condition that an EOLO2 powerful aerator is installed on the water surface of 766 m2, the dissolved oxygen of 1 to 3 aeration carbon heads 3.2 per box connected to the aeration pipeline can reach more than 3.5 to 4.0 mg/L, making the unit The area fish culture can be effectively improved; the pump is used to generate micro-water flow and regularly sprinkle photosynthetic bacteria to improve the water quality and provide open bait for fry; the water inlet of the pump is connected to the movable decontamination hose at the bottom of the pool , which is conducive to the timely removal of fish excrement and bait residues, and promotes the growth of fish.

The utility model has the advantages of: 1. It can make full use of fish farming waters with different areas; 2. It saves bait; 3. It is beneficial to control the water quality, reduce the incidence of fish and improve the curative effect of fish diseases; 4. It is convenient to change the breeding according to market changes 5. It is beneficial to increase the amount of fish cultured per unit area; 6. It can be applied to the breeding of broodstock, spawning and hatching of fish species, to the cultivation of commercial fish, providing the basis for industrial production lines.
