For the use of cages, it is also necessary to pay attention to cleaning, because after a long time, if you do not pay attention to cleaning, it will affect the fish and shrimp farming.
In the method of cleaning the cage, one is the manual cleaning method. This method is commonly used for sporadic cages. The net is lifted every 5 days or so, and the broom, branches, brushes, etc. are scrubbed and beaten. . Then the sun exposure method, the net body is half exposed to the water surface, let the sun shine, and the filamentous algae and other organisms attached to the cage are sunburned, converted to the other half of the box, or replaced the cage with more attachments. In the sun, expose to the sun, attach to the dead creatures, and slap clear. Then there is the mechanical cleaning method. When working in a large area, the cage is hoisted and flushed with a high-pressure water gun to remove dirt from the cage.
There is also a biological removal method. The fish in the box are mixed with algae, such as squid, tilapia, and scorpion. This method not only saves labor, saves money, but also increases fish production per unit area.
