The present invention relates to a submersible breeding system and method for aquatic creature seedlings [fry of aquatic creature]; especially about a submersible breeding system and method for crustacean seedlings; more particularly about A spherical type [spherical type] aquatic organism seedling submerged cultivation system and method thereof.

For example, aquatic organism seedling breeding or bait training devices are commonly used, such as the new patent of "improved nine-hole seedling cultivation plate" in the Republic of China Patent Announcement No. TW-109577, which discloses a nine-hole seedling cultivation plate. The nine-hole seedling cultivation board includes a seedling cultivation board, a fixture, an auxiliary growth frame and a curved cultivation frame.

As mentioned above, the seedling raising plate of No. TW-109577 has a surface, and the surface is in the shape of a regular rhombus. The seedling raising board has an upper end and a lower end, and the upper end and the lower end are bent into an arc-shaped circular hollow slot, and the arc-shaped circular hollow slot can be used for penetrating an iron rod. The jig is a long hollow jig, and the upper end of the seedling raising board can be buckled on the jig, so that the jig can straddle the two sides of a seedling raising frame. Both sides of the seedling raising rack are respectively provided with a cross bar, and a groove is reserved for each of the cross bars, so that the clip can straddle the cross bars on both sides of the seedling raising rack.

Inheriting from the above, the auxiliary life frame of the aforementioned TW-109577 is in the shape of a rectangular plate, and several round holes are arranged on the surface of the rectangular plate, and the two sides of the rectangular plate are bent upwards. Fold into an inclined surface at an appropriate angle. in the A long groove is arranged in the center of the rectangular plate shape, and the long groove has an opening, and the opening is an upward opening. In this way, the lower end of the seedling raising board can penetrate into the long groove, so as to complete the combination of the seedling raising board and the auxiliary growth frame. Then, according to this method, another seedling-raising plate and the auxiliary growth frame are combined with each other, so that several seedling-raising plates are arranged to straddle the seedling-raising frame.

Another common aquatic organism seedling breeding or bait training device, for example: the Republic of China Patent Announcement No. TW-328682 "New Biological Structure of Cleaning and Concentrating Fry Breeding Feed", which discloses a biological structure of fry breeding bait. The fish fry breeding bait biological structure comprises a hollow cylinder, a drainage pipe, a screen, a porous air pipe and a support seat.

Continuing from the above, the hollow drum of the aforementioned TW-328682 is a hollow drum without a top cover, and the hollow drum has a bottom surface, and a hole is provided in the center of the bottom surface of the hollow drum. The drain pipe is passed through the hole, and the drain pipe is pivotally connected to the hole. The screen comprises a fine-mesh outer layer net and an inner support net, and the inner support net is a metal support net, and the metal support net has a mesh of about 1 cm. The screen is arranged on the bottom surface of the hollow drum, and the screen is arranged at an appropriate distance from the periphery of the drain pipe.

Continuing from the above, the porous air pipe of No. TW-328682 is surrounded by the joint between the outer layer of the screen and the hollow drum, and an air blowing pipe is connected to the appropriate place of the porous air pipe, and the support seat is arranged on a drum seat lower end. A plurality of live biological bait for fish fry and water are introduced between the drum and the screen, and oxygen is pumped into the water by using the gas pipe to increase the survival rate of the live biological bait for fry.

As mentioned above, when the aforementioned No. TW-328682 covered the drainpipe on the water surface, the water could be discharged in the drainpipe by a downward suction force. At this time, the impurities and grease in the water can pass through the screen and be discharged. Additionally, gas can travel up the screen to prevent the fry live biological bait from clogging the outer mesh of the screen.

Another conventional aquatic organism seedling rearing system and method thereof, for example Such as: the invention patent of "aquatic organism seedling breeding and baiting system and method" No. TW-I656835 of the patent announcement of the Republic of China, which discloses a kind of seedling raising and baiting system.
