The coarse container is assembled by an upper cover plate and four rectangular plates. Two plates are oppositely arranged in a V-shaped inclined manner, the included angle is 55 degrees, and the other two plates are vertically arranged and are respectively connected to the two ends of the two plates which are arranged in the V-shaped inclined manner; the four plates form a container with an upper opening, and the container is matched with an upper cover plate to form a coarse container. The obliquely arranged plates are called sloping plates, and the vertically arranged plates are called vertical plates. Two risers play the effect of solid thick container of mark simultaneously, mark two swash plates of thick container and make whole thick container of mark draw in gradually from top to bottom in vertical direction, mark the thick in-process at the fry and throw opening bait that feeds excessively and organic matters such as excrement and urine that the fry produced along the inner wall that the thick container of mark inclines sink, can effectual concentrated organic matter, do benefit to the organic matter of discharging. So as to reduce the condition that the fry is sick or dead due to the breeding of harmful microorganisms and further improve the survival rate of the fry. Meanwhile, the structure that only one set of opposite side inclined plates is arranged instead of two sets of opposite side inclined plates enables the whole coarse container to have larger volume.
Two water inlets are arranged at the upper part of the vertical plate at one side, a water outlet is arranged at the lower part of the vertical plate at the other side, and a seedling emergence opening is arranged at the lower part of the vertical plate at the other side and is higher than the water outlet; the water outlet pipe and the two water inlet pipes respectively penetrate through the water outlet and the two water inlet ports and horizontally extend to the inner wall of the vertical plate on the other side.
The water inlet pipe is provided with a plurality of nozzles which are arranged along the axial direction of the water inlet pipe and the spraying directions of the nozzles are staggered. Water enters from the water inlet pipe and is atomized and sprayed out through the nozzle, the contact area of small water drops and air is increased after atomization, and the dissolved oxygen degree of water is further increased. In addition, when the atomized water drops uniformly fall on the water surface in the standard coarse container, the impact force of the water flow on the fry can be almost ignored because the water flows integrally and the total flow is small, and severe water flow cannot be caused. The condition of bruising or death caused by water flow impacting the fry can be effectively reduced, and the survival rate of the fry with thick mark is greatly improved.
The water outlet pipe is provided with a plurality of water outlet holes, water and organic matters are discharged after entering the water outlet pipe through the water outlet holes, the water flow in the thickening container is ensured to tend to be stable in the water discharging process, and the impact of violent water flow on the fry is avoided.

The filter screen is a nylon screen with the aperture of 0.5mm, and can pass bait organisms such as fairy shrimp, rotifer and the like, but can not pass the fry. And after the fry marking is finished, transferring the fries from the fry emergence opening to an outer pond or a large pond for subsequent culture. The organic matter and water are discharged from the drain port.
The light induction lamps are horizontally arranged on the inner wall of the upper cover plate in rows, are parallel to the water inlet pipes and are positioned between the two water inlet pipes. Due to the natural phototaxis of most fresh water fries, the fries are concentrated above the standard thick container as much as possible under the action of the light induction lamp and the inflow micro-water flow. Can effectively reduce fry and filter screen contact like this to reduce the condition that the fry died because of touching the filter screen.
The one end of standpipe I is located the one end in the thick container outside of mark through tee bend I and outlet pipe and is connected, and the other end passes through tee bend II and is connected with standpipe II, and a port level of tee bend II sets up as the delivery port. The height of the water outlet is lower than the highest water level of the standard coarse container. The vertical pipe I, the vertical pipe II and the tee joint II can rotate around the tee joint I to adjust the relative position of the water outlet. According to the siphon effect principle, the water level in the standard thick container can be adjusted by adjusting the angle position of the vertical pipe I through rotating the tee joint I.
