I. Facilities Construction
1. Site Selection Open the backyard of the house to build a pond in the backyard of the house and use groundwater or tap water as the breeding water source.
2. The Dianchi Lake is constructed of single bricks and is usually made of single bricks. The area is 2 square meters (2 meters in length and 1 meter in width). The interior and exterior walls and the bottom surface are cemented. The wall height is 50 centimeters. T type, play the role of anti-escape. On the wall 30 cm away from the bottom of the tank, a 10 cm diameter plastic-rubber pipe overflows. The bottom of the pool should lead to a certain degree of inclination to the drainage outlet, so as to be able to drain the pool water, the drainage outlet communicates with the total drainage channel. Walls and pool bottoms less than 20 cm from the bottom of the pool are tiled. Spills and drains are made of iron wire to prevent escape from the net. When not in use, they are plugged with corks.
3. The reservoir shall be built with a ratio of 1.5 cubic meters of water reservoir per 10 square meters of dilapidated pool. The reservoir shall be built with red bricks, and the internal and external corners, bottoms of the wall shall be used, and all cement shall be used. Install the outlet pipe at the bottom of the tank. At the same time, the bottom of the pool should have a certain degree of inclination, and the sewage outlets should be regularly cleaned. The outlets and outlets should be controlled by valves. Reservoirs are required to be leak-proof to ensure water supply safety. The bottom surface of the reservoir should be 20 cm above the bottom level of the culture pond.
Second, breeding technology points
1. Dianchi Lake Preparation After the Dianchi Lake is built, it is filled with water. After soaking for 10 days, lime water of 0.2 kg of lime is used to disinfect the pond mouth and the environment. One month prior to seedling, the water was added to a depth of 20 cm, and the tile was soaked so that attached organisms and mosses grew on the tile to reduce the reflection of light from the tile. One week prior to the release of the seedlings, some washed and disinfected water peanuts were placed around the inside of the pond, and the center of the pool left empty water for the feeding site of the yellow locust. At the same time, one quail and a few loach were stocked in each pond.
2. The seedlings are generally bought in early April. For seedlings, it is better to use cages to catch no injuries. It requires strong physique, active swimming, and neat specifications. There are 30 or so per kilogram, and stocks with different specifications should be stocked in separate ponds. Before stocking, soak the seedlings with 3% saline for about 5 minutes. It is advisable to stock 5 kg per square meter to ensure that the specifications for sale in the current year exceed 150 grams.
3. Feeding When the water temperature reaches 18°C ​​or more, the crickets open their food. However, the seedlings stocked in the pond have poor appetite within the first few days and generally do not take food on their own initiative. From the 4th day onwards, they can acclimate their food and start to trap their openings with live quails or cut into 4 cm, 1 cm and 1 cm long bait with fresh shank meat. After a few days, artificial diets can be fed: with appropriate amount of wheat flour, fishmeal is added, and bar-shaped bait is made by a meat grinder, and it is cooled and then fed into half-dried food. Feeding once a day in the evening, the amount of feeding was calculated as 3%-5% of the total weight of the carp in the pond. Generally placed in the hollow water of the pool, it is not only convenient for observation of feeding conditions, but also conducive to the removal of residual bait.
4. Daily management First of all, adhere to the patrol pool every morning and evening, find out the disease, kill the seedlings in time to isolate and diagnose the cause. Followed by the close monitoring of water quality changes, the general season 3-5 days to change the water, the high temperature season, changing the water once a day, change the water generally in the morning. When the water temperature exceeds 28°C, the fabric can be shaded with a shelf to provide significant cooling effect.
5. The principle of prevention of disease prevention and prevention, because the scutellaria is mainly based on the sense of smell to find food, its sense of smell is quite developed, it is very sensitive to the peculiar smell of the drug, the food has odor, its food intake is significantly reduced, and even refused to eat. Therefore, drugs cannot be used to prevent rickets as often as farmed fish. Only ecological precautions can be taken, such as breeding grasshoppers and loach in ponds. It is best to use less or no drugs.
Grow without shell Pumpkin Seeds Kernels have the effect of reducing pain, fixing eyes, etc. Raw food can sterilize and kill insects. Cooked food can improve your immunity.Because it is no shell, so it is more convenient to eat.
