Artificial cleaning: when the net box on the attachment is relatively small, you can first use your hands to lift the net clothes, and then shake off the dirt, or directly immersed in the water to clean the net clothes. When the attachment is too much, can use the toughness of the bamboo sheet pumping, make it shake off. Operation should be careful to prevent injury to the fish, broken nets.
Mechanical cleaning: the use of water spray guns, submersible pumps, with a strong current to the nets on the dirt washed down. Some use agricultural sprinklers, arranged in a small wooden boat, another boat to install a boom, the net box of various surfaces lifted in turn for rinsing. Two people operate, rinse a 60 m 2 net box about 15 minutes, than the hand scrubbing to improve the efficiency of 4 to 5 times, and reduce the labor intensity, is now commonly used methods.
Sinking box method: a variety of filamentous green algae in general in the water depth of 1 meter below the difficult to grow and reproduce. Therefore, the closed net box sinking to 1 meter below the surface of the water, you can reduce the net coat on the attachment of epiphytes. However, this method often affects baiting and management, which is unfavorable to the growth of fish, so the use of this method should be adapted to local conditions and weigh the pros and cons before making a decision.
Biological cleaning method: the use of channel catfish, tilapia and other fish like to scrape epiphytic algae, swallowing filamentous algae and organic debris habits in the nets properly put these fish, so that they scrape the nets on the attached organisms, so that the net coat to keep clean, the water flow smoothly. The use of this biological cleaner, not only can make full use of the bait organisms in the net box, but also increase the breeding species, improve fish production.
