Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a special incubation device suitable for red porcini fertilized eggs. Background Technology

[0002] Red croaker belongs to the order Siluriformes and family Croakeridae in the class Osteichthyes. It is a precious and endangered freshwater bottom-dwelling fish, mainly distributed in the Yuanjiang River in my country, the Red River and Ma River in Vietnam, and northern Laos. It feeds on animal food and is a river migratory fish. When breeding, it lays drifting eggs.

[0003] With the development of water resources in the Red River, the Nansha and Madushan hydropower stations have been built one after another. The dams have blocked the migration channels of the red pufferfish, destroyed the natural environment for the drifting and hatching of its fertilized eggs, narrowed its habitat and spawning grounds, increased the difficulty of population reproduction, and seriously affected the recovery and growth of the red pufferfish population. Therefore, artificial breeding technology is urgently needed to provide support.

[0004] The current method of hatching red porcini fertilized eggs relies on general-purpose incubation equipment or simple containers, which presents several challenges: First, the water flow design lacks specificity, causing fertilized eggs to easily settle at the bottom, leading to local hypoxia, fungal growth, and affecting embryonic development. Secondly, the temperature control is not precise. Existing equipment mostly uses simple heaters, and the temperature difference often exceeds ±1°C. Red pufferfish fertilized eggs are sensitive to water temperature, and the optimal incubation temperature is 25-28°C. Temperature fluctuations can easily lead to abnormal embryonic development or death. Third, the egg bed structure is unreasonable. General-purpose egg beds cannot effectively isolate fish eggs, which can easily cause mechanical damage and make cleaning and observation inconvenient. The aforementioned problems severely restrict the large-scale development of red pufferfish farming. To address this, this utility model provides a special incubation device suitable for red pufferfish fertilized eggs. Summary of the Invention

The other end of the Venturi tube is connected to a guide pipe extending to one end of the incubator.

[0008] As a further technical solution of this utility model, one end of the drain pipe passes through the incubator and is connected to its internal bottom end, and the surface of the guide pipe is evenly distributed with guide holes to form an induced water flow inside the incubator. A PLC control box is also installed on the outer wall of the incubator.

Start the device preheating and water circulation test run, and stop the operation after the water temperature stabilizes and the water flow is normal. Next, pull out the incubation egg bed 8 through the handle 82, and evenly spread the fertilized eggs of the red-billed tadpole on the surface of the egg bed (the density is controlled at 500-800 eggs / square meter). Then, install the egg bed back into the incubator 1 by locking the block 81 and the slot 83. Then, start the water circulation system 2 and run it according to the set parameters to form a periodic slow flow. The temperature sensor 7 monitors each incubation area in real time and adjusts the water temperature to maintain the temperature within the set range. During the incubation process, the development of the fertilized eggs can be observed regularly by pulling out the incubation egg bed 8. The egg bed is cleaned every 24 hours to avoid the accumulation of impurities. Once all the fry have hatched and are able to swim, the electromagnetic flow valve of the discharge pipe is opened via the PLC control box 3, and the drainage flow rate is adjusted to 10 liters / minute. The fry are carried by the water flow through the fry collection port 42 into the fry collection box 5. After the fry collection is completed, the electromagnetic flow valve is closed, the bolts on the connecting flange 41 are removed, and the fry collection box 5 is transferred to the nursery pond to complete the entire hatching process.
