2. Grid trapping. Put a net of 2~4 square meters in the water, and the bait that Monopterus albus likes to eat is placed in the middle of the net. Then cover the reed mat or straw bag and sink into the water. After about 15 minutes, quickly lift the four corners, open the reed mat or straw bag, and catch a large number of Monopterus albus, and the fishing rate is as high as 80%~90%.
3. Eel cage trapping. A number of eel cages are made of barbed bamboo, and baits such as earthworms are put in them. Generally, 70%~80% can be caught in the bottom water.
4. Hook and grab. You can use eel's favorite earthworm as bait.
5. Grab the straw bag. Put the feed in a straw bag and put it in the usual feeding place, and the eel will get into the straw bag and lift it up.
6. Grab the haystack. Make small piles of weeds and put them on the shore or in the four corners of the pond. After 3-4 days, enclose the haystack in the net with a net, and tie both ends tightly so that the eel can't escape. Remove the grass from the net and the eels will fall into the net.
7. Capture by forced aggregation method. The following drugs can be selected: ① tea seed cake. About 5 kilograms are used per mu of paddy field. The tea seed cake should be roasted and crushed with quick fire, and the particle size should not be greater than 1 cm. To put it in a bucket, soak it in 5 liters of boiling water 1 hour. ② Croton. Crushing croton and concocting into paste. Use 250g per mu of paddy field, add water 15kg, and spray with a sprayer. Three peppers. Select the hottest seven-star pepper, soak it in boiling water 1 time, and filter; Soak in boiling water 1 time, filter, take twice filtered water, spray with sprayer, and the paddy field filtrate is 5 kg per mu. Forced aggregation method can be divided into two types: ① forced aggregation method with running water is used to irrigate rice fields. At the water inlet of the field, two 50-cm-long mud ridges are made, so that water can only flow into the field through a short channel, and 2~3 water outlets are opened on the ridges opposite to the water inlet. Sprinkle or spray aggregation promoting substances in the field, drag them in the field with a rake, and force Monopterus albus to flee. When it is observed that most Monopterus albus escape, open the water inlet and let the water flow throughout the site. At this time, Monopterus albus swam upstream into the short canal, and then was caught, and the small one was released, and the big one was put into clear water for temporary breeding. ② The paddy field unsuitable for irrigation and drainage adopts static water forced aggregation method. Prepare a semi-circular frame net or shallow basket. Rake up the mud pile above the water level in the field, pile mud around the field every 10 m to make it 5 cm below the water level, put a semicircular framed net or a laundry list with a bottom on it, and then pile the mud on the net or laundry list to be 15 cm above the water level. When applying polymerization promoters in the field, the dosage should be less than that of flowing water method. Monopterus albus swims to the edge of the field when it feels uncomfortable, and once it meets a small mud pile, it drills in. When the eel is all in the mud, you can lift the net and basket to catch it. This should be done in the evening and retrieved the next day.
