There are many skills required to breed pufferfish. Management at every stage of the breeding process is very critical. Only by grasping the correct methods can we promote high yields and increase income and achieve wealth. Here I will introduce to you some issues that need to be paid attention to in the breeding process of pufferfish. 1. Selection of aquaculture waters The breeding cages should be placed in a water area that is sheltered from wind and light, has a quiet environment, fresh water, no pollutants, no obstacles, a wide water surface, good sunshine conditions, and a pool depth greater than 3 meters. In addition, hydroponic tanks, containers and rice fields can also be planted, but the water flow should be controlled within 0.1m/s, and the distance between the bottom of the cage and the bottom of the water should be greater than 0.5m to prevent the cage from running aground. The water area of the cage is generally 3~6m deep, and the dissolved oxygen is greater than 4mg/L. 2. Cage Management When the pufferfish is about 3 cm long, the mesh size of the cage is 6 meshes per square centimeter; when the pufferfish is longer than 8 cm, the mesh diameter is 1.5 cm. The general size of the cage is 5.0m × 8m × 2.5m, and the upper opening is 30cm from the water surface. In relatively open waters, the cage layout should be "needle" shaped, plum blossom shaped or "human" shaped, with a cage spacing of 15-30 meters. If two cages need to be arranged in an "I" shape due to water flow conditions, the two cages should be arranged in groups with a spacing greater than 50 meters. The area of the breeding cage accounts for about 4% of the set water surface. 3. Fish fry stocking Use water to test the cage 10-15 days before stocking. The fish species must be intact, disease-free, healthy, and strong. Before the pufferfish enters the cage, flow-through pond, or container, place an oxygen bag containing the fry in the water for 15 minutes. When the water temperature in the bag is close to the breeding water temperature, release the fry. Generally, there are about 12 per cubic meter. In order to prevent the growth of a large amount of moss in the water, pay attention to cleaning. 4. Feeding and Management Feeding should be fixed, fixed, qualitative and quantitative. Put an appropriate amount of water peanuts and other aquatic plants in the water body, and the aquatic plants account for about 20% of the water surface. One week before the release of pufferfish, sprinkle soy milk and primrose in the water to cultivate early bait for pufferfish. After adding pufferfish, start adding crushed fish paste and wheat flour mixed bait in a ratio of 3:1, and the feeding amount is 4% to 7% of the fish body weight. The bait is fed on the feeding table at 9 am and 4 pm. 5. Daily Management Pay attention to check whether the cage is deformed and clean the breeding pond in time. Check whether the fishing net is well dug every morning, noon and evening. Observe the fish and water frequently. Clean the cage in time. When cleaning the cage, usually clean the accessories on the cage. Be careful not to hurt the fish. In addition, move the cage in time according to the water quality and water quality changes. When the cage position drops or before the flood season, the cage should be moved to a safe water area with suitable water level in time. The above are some precautions about pufferfish farming for your reference and learning. I hope it will be helpful to you. A better breeding experience is that you must pay attention to the water quality, breeding methods, water source pollution, some bacteria in the water source, and regular disinfection of the water source. These are all very good breeding experiences. Control the water temperature well, and make sure that the water temperature does not fluctuate more than 2 degrees Celsius, so that the pufferfish can grow well. It is also necessary to pay attention to proper feeding and water quality requirements. You can buy a book to learn about it. First of all, you should learn professional breeding techniques, improve your breeding level, choose a suitable farm, pay attention to water quality, and also pay attention to bait issues. Clean and disinfect regularly to keep the water clean and hygienic, and be sure to take timely prevention and control measures against diseases. |
