Description

Technical Field

[0001] The invention belongs to the technical field of clam breeding, and in particular relates to a device and a method for breeding planktonic larvae in the process of breeding clam seedlings. Background Art

[0002] Philippine clam: also commonly known as variegated clam or Philippine clam, the shell length is 2.5-5.7 cm. The commercial size is an average of 40 mm. It is a common shellfish. The shell is solid, the shell valves are equal on the left and right; the two sides are unequal, and the beak on the top of the shell is located in the front half; the shape is slightly oval. The ligament is embedded and does not protrude from the shell surface. The wide and thick brown oval arched body extends almost to half of the rear edge. It is a shellfish seafood product, widely distributed in the southern and northern seas of China. It grows rapidly, has a short breeding cycle, strong adaptability (wide temperature, wide salt, wide distribution), and a long survival time out of water. It is an excellent shellfish suitable for artificial high-density breeding. It is one of the four major farmed shellfish in China. It is a species from the subtropical to low cold temperate zone of the western Pacific Ocean, and is distributed in the temperate zone of Europe. Wild populations are around the Philippines, the South China Sea and the East China Sea, the Yellow Sea, the Sea of ​​Japan, the Sea of ​​Okhotsk, and the Southern Kuril Islands. Its breeding began with traditional fishing activities in these areas by collecting wild clam seed.

[0003] The cultivation of clam seedlings generally includes the following steps: construction of nursery ponds, cleaning of nursery ponds, cultivation of biological feed, selection of broodstock and induction of spawning, egg washing, hatching, cultivation of planktonic larvae, cultivation of juveniles, selection of sea areas for intermediate seedling cultivation, cleaning of mudflats, transplantation of juveniles, sea area management, and seed washing, a total of 12 steps. Among them, the patent document with patent application number 201510092204.7 discloses a cultivation technology for thick-shelled mussel planktonic larvae, in which feeding management is required, and manual feeding is required at 8 am, 2 pm and 8 pm every day, and both require manual feeding. The feeding and management are labor-intensive. At the same time, the feed is easily piled up and cannot be dispersed inside the cultivation pond, which reduces the cultivation effect. In addition, the water quality inside the cultivation pond is prone to low pH. If not followed up in time, it will easily lead to the planktonic larvae being cultivated in acidic water, and the mortality rate of planktonic larvae will increase. Moreover, when the pH is artificially adjusted, quicklime is also sprinkled inside the cultivation pond, and the quicklime cannot be evenly distributed inside the cultivation pond, further reducing the cultivation effect. For this reason, we proposed a planktonic larvae cultivation device and method during the cultivation of clam seedlings. Summary of the invention

[0014] The method for cultivating planktonic larvae during the cultivation of clam seedlings comprises the following steps:

[0015] S1: Soy milk or young shrimp mixed feed is used as artificial auxiliary bait, and then it is mixed with water and poured into the adding box, and then quicklime is poured into the storage box. By setting the timer in the control box, the single-chip microcomputer controls the drive motor b to start after a period of time, and the drive motor b drives the threaded shaft to reciprocate in the forward and reverse directions. The threaded shaft drives the transmission plate to move back and forth through the threaded transmission, and the transmission plate drives the storage box to move, and the storage box drives the adding box to move, so that the storage box and the adding box move in the direction of the support plate. At the same time, the adding box drives the first shaft body to move, and the first shaft body drives the guide gear to move. During the movement of the guide gear, it will mesh with the guide racks opened on the three side walls of the support plate to drive the first gear. The shaft body rotates by itself, so that the first shaft body drives the stirring blade to rotate, so that the stirring blade mixes the soybean milk or the young shrimp compound feed with the water source, and at the same time the first shaft body drives the second pulley to rotate, the second pulley drives the first pulley to rotate through the connecting belt, the first pulley drives the second shaft body to rotate by itself, so that the second shaft body drives the incomplete gear to rotate, and the meshing transmission between the incomplete gear and the adjusting rack drives the circulation plate to move back and forth, and the sealing cloth is used to form a negative pressure inside the cavity during the forward and backward movement of the circulation plate, so that the feed inside the addition box is mixed and then enters from the circulation pipe, and then is sprayed out from the nozzle, so that the feed cultivates the planktonic larvae inside the cultivation pool, and because the addition box moves along the surface of its support plate all the time, the feed is evenly sprayed on the surface of the cultivation pool;

[0016] S2: At the same time, the first shaft drives the pulley three to rotate, and the pulley three drives the pulley four to rotate through the transmission belt, so that the pulley four drives the fourth shaft to rotate by itself, and the fourth shaft drives the scattering blade to rotate by itself, so that the scattering blade scatters the feed sprayed into the cultivation pool to improve the cultivation effect;

When the PH detector detects the PH of the water source inside the cultivation pool in real time, when the PH of the water source inside the cultivation pool is low, the single-chip microcomputer starts the stepper motor after receiving the signal, and the stepper motor drives the limit plate to rotate, so that the limit plate is set vertically, so that the limit plate and the telescopic end of the inching switch are on the same horizontal line.
