Fish live in the water, giving fish a food and eating table, and fostering the habit of feeding and holding fish. It can not only save food, improve the utilization of food, but also observe the growth of fish and facilitate management.
Different aquaculture species have different dietary habits, and the methods for setting up food establishments are also different. However, as a whole, there are buoyancy and sinking in food establishments. The materials used to erect the food premise include bamboo rafts, wooden rods, reed mats, bamboo mats, and polyethylene mesh fabrics. The shape of the table is square or triangular. The floating food table is generally frame-shaped, with corners fixed with wooden stakes and an area of ​​10 to 20 meters. The bait stations for raising upper and middle fish can be set at about 30 cm below the surface of the water, and the ground fish can be set at 1.2 meters below the water surface near the shore.
As the season changes, its position must be adjusted appropriately. The spring should be shallow and the summer should be deep. In autumn, the height should be adjusted. When the weather turns cold, it must be gradually deepened to ensure that the fish are always fed in a moderately warm water body. Bean cakes, rapeseed cakes and other large-grained foods can be fed on sink tables for bottom fish such as squid and squid. In a variety of fish-enriched bodies of water, it is possible to combine submerged and floating food tables, feed the floating bait first, and then feed the bait. In this way, the feeding time of various fishes can be staggered without affecting each other and saving food.
As the fish food table is soaked in water for a long time, the materials used to make the food table are rotable. Care should be taken to ensure that the food table is immediately replaced or repaired. Usually, we must clean the food court, clean up the food table, remove the bait and decayed material, keep the environment clean, prevent water quality from deteriorating, and cause pathogens to breed. The active food station can start from time to time and be sterilized by sunlight. After clearing the pond and catching the fish, the food table materials should be properly preserved. In addition, it is also necessary to use an aqueous solution such as bleaching powder to spit on the table occasionally to clean the food market.
