The number of times the fish farmers pull the net depends on the specific situation, such as short transportation distance in separate cultivation. After general 1 netting practice, it will be fine. If the distance is long or the operation time of summer flower fingerlings is long, you need to exercise 2-3 times. The interval of each net pulling should be 1 day. In the intensive training of the first net, the action of pulling the net should be steady and fast, so that the summer flower population is in a semi-water state for about 10 minutes, and immediately return to the pool. Time should not be prolonged, and at the same time, only 1 net should be pulled to avoid scratching the fish and causing dead fish. When there is wind, you should get off the net from the downwind of the pond and pull the net against the wind, which is convenient to operate.

The second net is the key 1 net in the whole fish training process. You should choose a sunny morning (9- 10) for netting exercise. Before pulling the net, set a 1 cage (made of polyethylene or wire mesh cloth) at the edge of the pool. The cage is rectangular, and the mesh is as big as a mosquito net cloth. One end of the cage is the entrance (box mouth) of the young fish, and the other end is the box tail. Then start pulling the net at the end of the box. When pulling the net, slowly push it along the edge of the pool to the mouth of the box. The speed of pulling the net must be balanced, steady and slightly slow. Butt the two ends to prevent fish from swimming back out of the net and minimize fish from leaking through the net. When the two sides of the net are close together, put away the rope below. On the side near the mouth of the box, put the upper and lower ropes on both sides of the box respectively, so that the fishing net is closely connected with the cage, and then slowly close the net and take it out of the cage.

When closing the net, be careful not to let the sludge and dirt in the net enter the cage with the fish, so as not to deteriorate the water quality and suffocate the fish. When the net is finished, pull the second net until all the fish are caught, so that all the fish in the pool can get a chance to exercise and the summer flowers coming out of the pool can have the same physique and firmness. When all the summer flowers are in the cage, pull out the upper and lower layers tied to both sides of the cage and lift the box mouth to make the fish in the cage. At rest, someone should splash water gently at one end of the cage to cause water flow, so that the fry can go upstream and the dirt floating on the water surface can be washed downstream. Then use bamboo poles to lift the bottom of the cage from the downstream end to slightly above the water surface and gradually move to the upstream end. Finally, the fish are separated at the upstream end of the cage, and then the fish manure and other pollutants deposited at the bottom of the cage are washed away, and the net clothes are shaken to wash away the mucus to keep the water flowing smoothly inside and outside the cage. Remove the separated bamboo poles and let the fish disperse in the whole cage. You should stop in the cage for 2-3 hours, not too short. When the fish is fully trained, go to the cage and put the summer flower fish back to the original pond. Pay close attention to the activities of fish when they are crowded in cages. If you find that the corner of the cage is too crowded, you can splash some water in a dense place to evacuate temporarily. If the floating head of summer flower fish is serious, it should be put back into the pool as soon as possible. The length of exercise depends on the tolerance of fish. Fish are strong and have low density, so the time of close packing can be longer, otherwise the time will be shorter.
