Fry breeding box for hatching of Sinogastromyzon

Abstract

The invention relates to the technical field of aquaculture, and discloses a fry breeding box for hatching of Sinogastromyzon, which comprises a fry breeding box. The left side of the lower surface ofthe fry breeding box is provided with a water pumping opening, a filtering box is arranged on the upper portion of the rear side of the fry breeding box, a water pump is arranged on the upper portionof the left side of the filtering box, and the input end of the water pump is connected with a water pumping head through a water pumping pipe. A first fixing base is arranged on the right side of the fry breeding box, the end of the first fixing base is fixedly connected with the water pumping pipe, the water pumping head is connected with the lower portion of the water pumping opening, the lower portion of the right side of the filtering box is connected with a water inlet head through a water inlet pipe, and the water inlet pipe is connected with the right side of a water inlet. A second fixing base is arranged on the right side of the middle of the fry breeding box, a feeding trough is formed in the middle of the second fixing base, and a first water permeable hole is formed in the lower portion of the feeding trough. According to the fry breeding box for hatching of Sinogastromyzon, by arranging the feeding trough and a pressing plate, feed originally floating on the water surface can be pressed into the water bottom, and the demand of the foraging habit of Sinogastromyzon is met.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a seedling box for hatching of Chinese loach. Background technique [0002] Seedling cultivation means the cultivation of seedlings. The original intention refers to the cultivation of seedlings in nurseries, hotbeds or greenhouses, ready to be transplanted to the land for planting. It can also refer to the stage in which various organisms are artificially protected until they can survive independently. As the saying goes, "the seedlings are strong and half harvested". Seedling raising is a labor-intensive, time-consuming and highly technical job. In the field of aquaculture, it is also called fry. [0003] Huasi loach is a small bottom-dwelling fish. The body color is relatively changeable, and the body shape is specialized. It inhabits the fast-flowing and gravel mountain streams and rivers, lives on the rocks, and feeds on algae and small invertebrates. In breeding, ...

[0004] Chinese patent (notification number: CN207978707U) discloses a kind of nursery box for loach hatching, comprising a nursery box, said nursery box is made up of an outer box layer and an inner box layer, and the center position of the bottom end of the inner box layer is provided with a residual The bait tank, the upper end of the residual bait tank is provided with deflectors inclined on both sides, the upper end of the deflector is provided with an adjustment filter, the bottom of the adjustment filter is provided with a sealing plug, and the top of the adjustment filter is provided with a fixed filter screen, pressure rods are provided at both ends of the surface of the regulating filter screen, a heating rod is provided between the inner box layer and the outer box layer, an oxygen generator is arranged on one side of the outer box layer, and an oxygen generator is installed on the oxygen generator An oxygenation pipe is connected, the outer surface of the outer box layer is provided with a heat insulation layer, the upper end of the seedling raising box is provided with a box cover, and the center of the bottom end of the seedling raising box is provided with a slag discharge port. The device can quickly and conveniently It can clean the residual bait at the bottom of the seedling box, and can protect the box from cold and heat according to the climate change, so as to increase the hatching yield of loach seedlings. However, Huasu loach cannot eat food floating on the water surface. On the surface of the water, it is difficult to complete the seedling cultivation of Huasi loach
