An indoor cement pond for the spawning of Micropterus salmonides

Abstract

The present invention relates to an indoor cement pond spawning nest for Micropterus salmonides, which includes an L-shaped connecting rod, a first triangular plate, a second triangular plate, a woven net and a plurality of palm pieces. In the present invention, two triangular planes arranged at an obtuse angle are formed between the L-shaped connecting rod, the first triangular plate and the second triangular plate. The woven net is adaptively laid on the two triangular planes, and then the palm pieces are detachably laid on the woven net. This structure can not only simulate the natural environment for the spawning of Micropterus salmonides, but also does not limit the free movement of Micropterus salmonides, thereby reducing the bruising of Micropterus salmonides and improving the spawning efficiency of Micropterus salmonides.

Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and particularly relates to an indoor cement pond Micropterus salmoides spawning nest. Background Art

[0002] Micropterus salmoides, commonly known as California bass, also known as black bass, belongs to the order Perciformes, suborder Percoidei, family Centrarchidae, genus Micropterus, and is native to North America. It is the main freshwater bass aquaculture variety in China.

[0003] Under natural conditions, Micropterus salmoides has the habit of building nests for spawning. Under artificial aquaculture conditions, an independent collection frame is usually set in the spawning pond, and multiple palm pieces are laid flat on the bottom of the collection frame. Then, the Micropterus salmoides to be spawned is placed in the collection frame. Although the fish eggs can be collected intact, the collection frame restricts the freedom of Micropterus salmoides and is not conducive to spawning. Moreover, the collection frame is very easy to bump into Micropterus salmoides, affecting the health of the spawning Micropterus salmoides.

[0004] Therefore, how to provide an indoor cement pond Micropterus salmoides spawning nest is an urgent problem to be solved by those skilled in the art.

[0005] Summary of the Invention

[0006] The present invention provides an indoor cement pond Micropterus salmoides spawning nest to solve the technical problems that the existing nest restricts the freedom of Micropterus salmoides and is easy to bump into Micropterus salmoides.

[0007] The technical solution for the present invention to solve the above technical problems is as follows: An indoor cement pond Micropterus salmoides spawning nest includes an L-shaped connecting rod, a first triangular plate, a second triangular plate, a woven net, and multiple palm pieces.

[0008] The L-shaped connecting rod is placed parallel to the bottom of the indoor cement pond; the first triangular plate is placed vertically on the bottom of the indoor cement pond and one of its corners is fixed at one end of the L-shaped connecting rod; the second triangular plate is placed vertically on the bottom of the indoor cement pond and one of its corners is fixed at the other end of the L-shaped connecting rod, and one side of the second triangular plate is fixedly connected to the adjacent side of the first triangular plate.

[0009] Two triangular planes are formed between the upper edges of the L-shaped connecting rod, the first triangular plate, and the second triangular plate, and the two triangular planes are arranged at an obtuse angle; the woven net is adaptively laid on the two triangular planes and its edges are respectively fixed on the upper walls of the L-shaped connecting rod, the first triangular plate, and the second triangular plate; the palm pieces are detachably laid and connected to the woven net.

[0010] The beneficial effects of the present invention are as follows: By forming two triangular planes arranged at obtuse angles between the L-shaped connecting rod, the first triangular plate and the second triangular plate, the woven net is adaptively laid on the two triangular planes, and then the palm pieces are detachably laid on the woven net. This structure can not only simulate the natural environment of Micropterus salmonides spawning, but also does not restrict the swimming freedom of Micropterus salmonides, thereby reducing the bruises of Micropterus salmonides and improving the spawning efficiency of Micropterus salmonides.

[0011] On the basis of the above technical solutions, the present invention can also be further improved as follows.

[0012] Further, both the first triangular plate and the second triangular plate are right-angled triangular plates, and one right-angled side of the first triangular plate and the second triangular plate are fixedly connected to each other; the other ends of the right-angled sides of the first triangular plate and the second triangular plate are respectively fixedly connected to both ends of the L-shaped connecting rod.

[0013] Further, the length of one right-angled side of the two right-angled triangles is 30 cm - 40 cm, and the length of the other right-angled side is 80 cm - 160 cm.

[0014] Further, it also includes an iron sheet and a magnetic sheet. The iron sheet is installed on the woven net; the magnetic sheet is fixed on the palm piece and can be magnetically adsorbed to the iron sheet.

[0015] Further, there are multiple iron sheets, and the multiple iron sheets are installed on the woven net at intervals.

[0016] The beneficial effect of adopting the above is: The installation position of the palm piece can be adjusted, thereby adapting to Micropterus salmonides of different body sizes.

[0017] Further, it also includes a telescopic rod. One end of the telescopic rod is installed with a handle, and the other end is installed with a hook, and the hook can be hooked on the mesh hole of the woven net.

[0018] The beneficial effect of adopting the above is: The telescopic rod can adjust the length to adapt to indoor spawning ponds of different depths. In addition, the hook can be conveniently hooked on the woven net, facilitating the picking up of the ovary.

[0019] Further, the L-shaped connecting rod, the first triangular plate, the second triangular plate and the woven net are all made of stainless steel.

[0020] Further, the width of the mesh hole of the woven net is 12 mm - 15 mm, and the length is 13 mm - 18 mm. BRIEF DESCRIPTION OF THE DRAWINGS
