Description

TECHNICAL FIELD

[0001] The utility model belongs to the aquaculture technical field, especially relate to a kind of green fin mace puffer factory cultivation feeding device. BACKGROUND

[0002] At present, there is no special compound feed for green fin mace puffer in the market, and the main feeding method in the breeding process is to feed frozen shrimp skin. Natural bait has the advantages of rich nutrition, good food attraction, easy digestion and absorption, and fast growth. However, during the process of factory cement pool breeding of green fin mace puffer, directly feeding frozen shrimp skin in the pool will cause intestinal spasm and enterogastritis of fry due to concentrated feeding of frozen shrimp skin that has not completely melted. After a long time, fry will die due to enteritis, and this feeding method will also cause some fry to overeat and some fry to underfeed, resulting in growth differences.

[0003] Therefore, it is necessary to design a green fin mace puffer factory cultivation feeding device to solve the problems of fry enterogastritis and growth differences caused by the above feeding methods. INVENTION CONTENTS

[0005] To achieve the above purpose, the utility model is implemented by the following technical solutions:

[0006] A green fin mace puffer factory cultivation feeding device, comprising

[0007] The floating frame is of rectangular structure, and comprises four PVC straight pipes, which are connected by PVC elbow pipes between adjacent PVC straight pipes.

[0008] The net bag is fixed at the bottom of the floating frame, and is of box body structure with open top, which is used to place frozen shrimp skin. The net bag is composed of a plurality of grid sheets made of polyethylene material, and has a plurality of holes in the grid sheet.

[0009] The traction soft rope is fixedly connected to one end of the floating frame.

[0010] Preferably, the floating frame and the net bag are fixedly connected by a plurality of nylon straps.

[0011] Preferably, the net bag comprises

[0012] The fixed net bag part is of annular structure and is connected by four grid sheets, and the upper part is fixedly connected to the floating frame.

[0013] The sliding net bag part is of box body structure with open top and is connected by five grid sheets, and is slidingly sleeved outside the fixed net bag part.

[0014] Preferably, the inner bottom of the net bag is fixed with a motor, and the output shaft of the motor is fixed with stirring blades.

[0015] Preferably, the top of the net bag is fixed with a lower magnetic strip, and the bottom of the floating frame is fixed with an upper magnetic strip.

[0016] The green pectoral fin pufferfish factory farming feeding device has the following beneficial effects:

[0017] Under the buoyancy of the floating frame, the floating frame can float on the water surface, and the net bag is immersed in the water. The device is fixed on the cement pool wall by the traction soft rope, and will not rotate with the water flow. After the frozen shrimp skin is thawed in the device, it will pass through the holes of the grid sheet and enter the cement pool breeding water area. At this time, the shrimp skin will no longer be frozen, and the green pectoral fin pufferfish fry will search for food around the device. In this way, after feeding, the green pectoral fin pufferfish fry will not cause enterogastritis due to overcooling, effectively avoiding diseases and improving breeding efficiency. At the same time, it can also ensure that the green pectoral fin pufferfish fry feeds more evenly and reduces the size difference in growth. BRIEF DESCRIPTION OF DRAWINGS
