When is the best breeding market for Monopterus albus? The middle and lower reaches of the Yangtze River and southwest China are suitable for seedling raising from the end of June to the beginning of July, and South China should be earlier. From May to early June this year, there was more rain in the Yangtze River basin, and the temperature was 3-5 degrees lower than that in the same period last year, which delayed the spawning time of eels. The middle and late June is the peak of eel spawning and reproduction. I hope you can buy a small amount of eel fry on a sunny day in June. The main specification is that only those whose body length is less than 20 cm or more than 26 cm can be used for box culture.

What preparations should farmers make before entering seedlings? Generally, cages are set 30 days before the eel species are stocked, and the size of the cages is 2*2, 2*3 and 2*4 square meters. Generally, cages are arranged in a single row or in multiple rows, each row is 2 meters apart, the cage spacing is 1 meter, and the upper edge of the cage is 40-50 cm above the water surface. Cages placed in small water bodies such as ponds are fixed, and the periphery of cages is fixed with bamboo frames or pulled by iron wires on the shore; The density of cages in ponds generally accounts for about 60% of the pond water area. Put the peanuts in a cage, and the peanuts in the box should be cleaned and disinfected. Generally, it should be soaked in 5- 10 ml/m3 concentrated glutaraldehyde for 5-10min. When the aquatic plants in the cage have turned green, the larvae of Monopterus albus can be released.

What should I pay attention to when buying seedlings? Miao Zi, a long-distance transport, suggested that anti-pressure products must be used in the transport box to prevent colds: sprinkle 5 grams of ginger/box. When you arrive at the destination pond, don't put the seedlings in a hurry. You must first adjust the temperature, cut off the residual strips, disinfect, classify the size and release the seedlings.

I often talk about the process of seedling raising. How is this process done? 1. Before entering the box: 10 The day before entering the box, use "quicklime" on the water once, 10kg/ mu, and sprinkle it outside the box. Five days before entering the box, kill insects and sterilize once: "concentrated glutaraldehyde 1 bottle+Jiakejing 1 bottle" with 3 mu of water, which should be splashed inside and outside the box. Culture plankton two days before entering the box: "2 packs of bait oxygen bar+algae species 100g = 1 mu", and use it once in the second half of the month.

2. In the box: 500 Jin of eel. Medication: "Sprinkle ginger 1 bag+50 ml of seed soaking agent+Cao Fang Vito 1 bag" and soak for 5 minutes. Note: it is very important to adjust the temperature and break the bar.

3. After coming out of the cage: use in the cage for 3 consecutive days: sprinkle 2 grams of ginger +2 grams of Sanhuang powder +2 ml of Junbiqing with water per square meter. On the third day, began to lure food.
