Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
1 is a cross-sectional view of the hatching tank for the attached spawning fish according to the present invention to produce fresh seedlings and fry by incubating the fish in the index or cyclic equations by supplying fresh water and sea water.
As illustrated in FIG. 1, the hatching tank 10 of the present invention is provided so that the support 11 is placed on the hatching tank 10, and the artificial spawning phase 12 is hooked to the support 11. 13), the plurality is arranged in a row vertically. That is, the artificial scattering bed 12 according to the present invention is hooked from the support 11 installed over the water tank so that the air bubbles and fresh water can be located in the middle layer so that the air bubbles and fresh water are well communicated under the water surface. It is preferable to use (13) to provide a plurality of lines in a vertical line.
In addition, the lower portion of the artificial scattering phase 12 implements a flow rate at which the scattering particles attached to the artificial scattering phase 12 do not drop, and provides oxygen of 50 to 100 microns to supply fresh water and oxygen to the scattered eggs. A microbubble generating device 14 for generating (air) fine dispersion is provided. The microbubble generating device 14 can expect a stable effect beyond the mother hatching the eggs.
In addition, according to the present invention, by providing the appropriate hatching conditions for each fish in the hatching tank 10, the circulating filtration device including the main drainage filtration so as to produce fry [seedling, larvae], lighting and heater cooling device (in the drawings Not shown) can be installed.
Artificial spawning phase 12 according to the present invention can be installed in a natural state not only facilitates egg laying, but also can be expected to provide an ecosystem control, that is, the effects of providing fish spawning places, habitats and hiding places, nurturing adult relatives in the laboratory or fish farm It is preferable to use an opaque PVC or transparent acrylic (opaque treatment) in the shape of a round pipe so that the volume can be within 2 to 6 times the adult female and male pair of fish. If the space of the artificial spawning phase 12 exceeds the volume of a pair of parent (mother) 6 times the efficiency of the crystal (fertilization) is reduced, if less than 2 times the access selectivity of the female is reduced. In addition, when the shape of the artificial laying phase 12 is not a circle but a square, such as a square, there are many eggs due to a decrease in fertilization rate, and there are many difficulties in collecting and hatching eggs.
