The market price of Huangqi before and after the Spring Festival every year is more than 2 times from April to September, and the goods are sold well. Therefore, a large-scale collection of wild jaundice in the cage for a short period of time in the autumn, and sales before and after the Spring Festival, can obtain substantial profits. The project has a low investment, simple operation, and quick cash flow, which is a good way for farmers to quickly increase income and get rich. The specific practices are as follows:
First, choose the waters to set up cages. It is best to choose the pond to set the waters of the cages, followed by the lakes, ditches and reservoirs with relatively stable water levels. Existing fish farming waters or cages can be used. However, no matter what kind of body of water, there should be sufficient water, good water quality and pollution, and good lighting. The cages are sewn with polyethylene mesh sheets. Each cage should have an area of ​​10 to 20 square meters and a depth of 1 to 1.2 meters. Net cages in the water are fixed with wooden stakes or float with oil drums. Before stocking up, Huang Biao cultivated a large amount of aquatic peanuts and other plants in the cages and allowed them to cover the entire cage for the yellow toads to inhabit.
Second, strictly control the quality of the box. Restocking time is generally completed around October of each year when there are a large number of jaundice and the purchase price is low. Adopted varieties do not need to pay attention. However, as with the conventional breeding of seedlings, it is necessary to strictly control the quality and require that cages be harvested by individuals who are disease-free and unharmed, so as to ensure the survival rate. It should be noted that the high temperature in the early autumn can easily cause fever and cause a large number of deaths. At the time of catching the yellow locust in the households of the stricken households, it is necessary to change the water more than twice a day and place it in a cool place. Acquired yellow cockroaches that have been kept for less than 2 days at the time of the catcher's house should be collected in the morning at low temperature. The transport time should be as short as possible. The reclaimed jaundice must be restocked in a timely manner.
Third, sub-filed to maintain strict disinfection. For the "universal goods" received by the Huanghua, they should be put into different cages according to the size of at least 3 grades. Stocking density is generally 2.5 to 5 kilograms per square meter cage, and the specifications of large stocking weight, small size stocking weight. Before entering the box, disinfect it with 3% to 5% saline for 5 to 10 minutes.
Fourth, the correct use of holding methods. 1 Feeding: After 3 days into the box, Huangpi began feeding fresh fish meat minced with a meat grinder and was fed once a day in the evening. The bait is put on the aquatic grass, and 3 to 4 feeding points per box are set, and the amount is eaten each time. In the middle and lower reaches of the Yangtze River, basically no food is available after the end of October (water temperature below 15°C). 2 Antifreeze: As the temperature gradually decreases, it is necessary to deepen the depth of the pool water and maintain the lush grass nets. 3 Anti-interference: When the temperature is low in winter, the activity of jaundice is very poor. It is necessary to resolutely put an end to turning the plants and agitating the pool water. Otherwise, the jaundice will fall into the bottom of the tank and unable to swim back to the aquatic grass to inhabit.
Fifth, grasp the timing of timely sales. In the winter, we should keep abreast of market prices, predict changes in market prices, and seize the opportunity to sell at the right moment to obtain the best return on holdings.
