Example Embodiment

[0021] Example one

[0022] Such as figure 1 Shown is the front view of the multi-layer fish farming device of the present invention; figure 2 Shown is the top view of the multi-layer fish farming device of the present invention. The multi-layer fish farming device of the present invention includes a top rectangular frame 1, a bottom rectangular frame 2 and a number of them arranged between the top rectangular frame 1 and the bottom rectangular frame 2. On the two pairs of uprights 3, the top rectangular frame 1, the bottom rectangular frame 2 and the uprights 3 are provided with fishing nets for forming the third layer of net cage 10, and the first pair of uprights 2 on the left is fixedly provided with a first The area of ​​the second frame 6 is larger than the area of ​​the first frame 7, and the first frame 6 and the second frame 7 are arranged up and down and are located between the top rectangular frame 1 and the bottom rectangular frame 2, so The top right side of the fir...

Example Embodiment

[0027] Example two

[0028] Such as image 3 Shown is a top view of another structure of the multilayer fish farming device of the present invention;

[0029] The difference between this embodiment and the first embodiment is that: preferably the top rectangular frame 1 is provided with a first connecting rod 13 and a second connecting rod 14 extending inwardly on the front and rear inner sides, and the length of the first connecting rod 13 Longer than the length of the second connecting rod 14, the first upright rod 4 is connected to the end of the first connecting rod 13, and the second upright rod 5 is connected to the end of the second connecting rod 14. This structure makes the second layer net The front, back and right side of the box extend the first layer of cages so that the fish in the second layer of cages can surface between the second layer of cages and the front, rear and right side of the first layer of cages For ventilation, the second layer of cages are extended ...

Example Embodiment

[0030] Example three

[0031] The difference between this embodiment and the first embodiment is that the preferred first upright 4 is located between the left upright 3 and the second upright 5 in the front-rear direction, and the structure of this embodiment enables the second layer of net cages The front and rear sides of the first layer of cages extend out of the first layer of cages, so that the fish in the second layer of cages can rise to the surface for ventilation in the area between the second layer of cages and the front and rear sides of the first layer of cages. The front and rear sides of the second layer of cages extend out, so that the fish in the third layer of cages can also surface in the area between the third layer of cages and the front and rear sides of the second layer of cages for ventilation.

Abstract

The invention provides a multilayer fish raising device comprising a top rectangular frame, a bottom rectangular frame, upright columns and a fishing net for forming a third layer of net cage; a pairof upright columns at the left side are fixedly provided with the first frame and the second frame; the area of the second frame is larger than that of the first frame; the top of the right side of the first frame is provided with first upright rods; the top of the right side of the second frame is provided with second upright rods; a first fishing net for forming a first layer of net cage is arranged among the first frame, the top rectangular frame and the first upright rods; and a second fishing net for forming a second layer of net cage is arranged among the second frame, the top rectangular frame and the second upright rods. The plurality of layers of net cages are overlaid in a cage body, and the areas of the plurality of layers of net cages are gradually increased from top to bottom,so that the multilayer fish raising device is simple in structure and capable of raising different kinds of fishes in batches and preventing big fishes from swallowing little fishes and preventing fishes in shallow water from scrambling for food.

Description

technical field [0001] The invention relates to the technical field of fish farming equipment, in particular to a multi-layer fish farming device. Background technique [0002] China has a vast sea area and a long coastline, but it has a large population. The daily fish food needs gradually increase with the improvement of people's lives. Therefore, fish farms usually achieve the purpose of increasing production by expanding the area of ​​fish farms. However, due to expansion and The area of ​​the fish farm is relatively large and the consumption cost is relatively high. [0003] In addition, due to the competition of different species of fish and the difficulty of catching, the same species of fish is usually raised in the same fish farm. demand for farming, which leads to the fact that the same fish farm cannot be fully utilized. [0004] Therefore, how to maximize the rational use of fish farms is a technical problem to be solved in the prior art, and aquaculture is dev...
