For a structure in which the column and the orifice plate are not integrally formed, in actual application, if the egg-laying and breeding container is large, a conventional structure such as a slot or a convex ring can be provided between the column and the orifice plate to limit the orifice plate, so as to prevent the orifice plate from moving downward under its own gravity; if the egg-laying and breeding container is small, this function can be achieved by directly utilizing the friction between the column and the orifice plate. For a structure in which the orifice plate, the column and the base plate are integrally formed, there is no problem of orifice plate movement.
[0008] Preferably, in order to facilitate quick assembly and disassembly, the egg-laying and breeding container is cylindrical and the outer wall of its lower end is provided with an external thread, and the hole cover is provided with an internal thread and is connected to the external thread at the lower end of the egg-laying and breeding container through the internal thread.
[0009] Preferably, in order to facilitate reliable installation of the filter, the edge of the filter is placed between the lower end outer wall of the egg-laying and breeding container and the inner wall of the hole cover.
[0010] Preferably, in order to facilitate observation and reduce product quality, the egg-laying and breeding container is a transparent plastic container, the hole plate is a transparent plastic plate, the hole plate mounting piece is a transparent plastic piece, and the hole cover is a transparent plastic cover.
[0011] The beneficial effects of the present invention are:
[0012] The utility model is designed with spawning and breeding containers, floats, orifice plates, orifice plate mounting parts, orifice covers and filter screens that cooperate with each other. When in use, the container is placed in a fish pond or fish tank, and the mother fish is placed in the spawning and breeding container and is located above the orifice plate. The float is used to make the upper part of the spawning and breeding container float on the water surface, and water is present in the middle and lower parts of the spawning and breeding container. The fish eggs laid by the mother fish or the fry directly born fall onto the filter screen through the orifice plate holes on the orifice plate. The fish eggs reproduce into fry, and the mother fish and fish outside the spawning and breeding container cannot eat the fish eggs and fry. Therefore, the fish eggs and fry are effectively protected while the fish eggs are allowed to reproduce normally in water. The utility model is suitable for use in small farms and households, and is particularly suitable for use in household fish tanks. BRIEF DESCRIPTION OF THE DRAWINGS
