On September 10th, after the article entitled “Aquarius Ornamental Fish Turned into “Auspicious Samboâ€â€, the editorial department received a lot of phone calls and text messages from the readers, hoping to learn more about how the protagonists in the following three-dimensional culture of turtles, crabs, and ornamental fish. To this end, this paper specifically introduces some of the culture techniques involved in the article as follows:
1. Fish ponds The best place to choose fish ponds is to choose between leeward and sunny, with fish ponds ranging in size from 1 mu to 10 mu.
The depth of the fish pond is generally about 1 meter, the maximum depth of the pond dam is 3 meters, and the height of the pond side is 80 meters high. The plastic film is 80 centimeters high on the ground and 20 centimeters underground.
2. After the seedling pool water is drained, the whole pool of 100 kg lime shall be sprayed evenly, and the water injection shall be started after 10 days. Fangmiao time: 4-5 months each year, but also in October. Number of launches: 300 to 500 turtle-frying pairs per mu, 300 turtles per mu, and 500 to 1000 per mu in Japan. Turtle, crab and ornamental fry can be put in succession, or they can be placed at one time.
3, feeding and management of ecological turtles May 1 each year, the water temperature reached above 22 °C began to gradually feed, artificial feeding a small amount of fresh material, such as wild freshwater fish. When the water temperature reaches 27°C, the amount of feed to be fed is increased to reach 6% of the weight of the turtle itself. It is best to put some live snails in the pond for turtles and crabs to eat freely. Japanese koi and red clams can feed fish pellets properly.
4. Disease Prevention and Control Regularly sprinkle lime 15kg/mu each month, the water quality maintains transparency of 30cm, and when the transparency of the pool water is more than 30cm, change the water or add new water. Ecologically cultured turtles and crabs rarely get sick. Ornamental fish is prone to fish and worm disease. In May-August, it is appropriate to sputter twice the crystal trichlorfon (90%), and the water depth of 1 meter in the pond can be controlled evenly by spraying 3 to 2 acres per mu.
