(1) The quality of water and water temperature are maintained for a long period of time, and no growth is required. It is only to increase the survival rate of the loach and reduce consumption, and to prevent wastage. The water temperature is 5-10 degrees, which is suitable for the temperature, and the density of the loach is large. Therefore, the water quality is very high. If fish is raised in cages or cages, the water quality should be clear, the water temperature should be low, and there should be slow-flowing waters; if the tanks or cement tanks are raised, it is necessary to choose well water as the water source, and the well water must have water before use. A longer process to aerate oxygen. When changing the water, note that the temperature difference should be small and the maximum must not exceed 3 degrees.
(2) Holding time. The purpose of holdings is different, and the length of holdings is not the same. If the holding time is long, the stocking density should be small, and in the middle, some animal feed should be fed in order to prevent the loss of mud weight. Feeding should be even, because in the holding environment, the loach activity is inconvenient. If the feeding is concentrated, the loach near the bait is much more likely to eat, easily bloating, affecting the intestinal respiration, and the loach far from the bait will not eat, it is easy to thin. If the holding time is short, you can increase the stocking density, as long as the ground observation, often changing the water.
(3) disinfection. Before entering the temporary holding environment for temporary conservation of mud, we must use salt water or malachite green solution for bath disinfection to prevent the occurrence of infectious diseases.
(4) Strengthen management. Loosening muddy for a short period of time, we must strengthen the management, ground observation, ground change water, ground cleaning. If you find a disease or die, remove it in time to see if it is an infectious disease. If so, take measures to prevent the spread of fish disease.
