In recent years, due to the large use of pesticides and the increase of fishing intensity, the natural resources of loach have decreased, and the artificial breeding of loach has become more and more popular for farmers. Since the waters of cultured loach are generally shallow and mostly in still water, the water quality tends to deteriorate. Therefore, in terms of disease prevention, scientific and rational feeding and fertilization should be paid attention, and the stocking density should be appropriate. New water is often added to keep the water fresh.
1. Feeding environment. Muddy breeding environments should be chosen where they are sheltered from the sun and near water sources. Loach does not require high water quality, but it cannot be cultured in waters that have been contaminated with pesticides or have high chemical concentrations. Before stocking, the ponds should be thoroughly cleaned and disinfected, and some aquatic plants should be planted in the pond to provide a shady, comfortable and quiet living environment for the loach. At the same time, the roots of the aquatic crops should also be some benthic organisms. The breeding site provides a natural food for the loach.
2. Seed quality. To choose a sturdy body, strong activity, smooth surface, disease-free and innocent muddy seedlings.
3. Seed disinfection. Before stocking, the seedlings should be bathed with 20-30 g/l salt water for 5 to 10 minutes to kill pathogens on the body surface.
4. Stocking density. During mud aquaculture, if the stocking densities are low, then water resources are wasted; stocking densities are too high, which can easily lead to plague. General stocking length 3 ~ 4 cm summer flower 100 ~ 150 / square meters, body length in more than 5 cm of seed can be stocked 50 to 80 / square meters, in good condition can be appropriate to increase the amount of stocking, otherwise To reduce the amount of stocking properly.
5. Feed management. Loach is a kind of omnivorous freshwater fish, especially like to eat leeches, silkworms and other plankton, but animal feed generally should not be fed alone, otherwise it will easily lead to bulimia, bulimia, indigestion, and abnormal intestinal respiration. Flatulence" and died. Decomposition of feed can not be fed, or muddy susceptible to enteritis and other diseases.
6. Water quality management. During cultivation, good water quality cultivation is an effective measure to reduce the cost of aquaculture, and at the same time meet the physiological and ecological requirements of loach, which can make up for the shortcomings of nutrient insufficiency and inconsistent feeding of artificial diet, and can also reduce the incidence of diseases and increase production. After the loach has been stocked, the topdressing fertilizer shall be applied in time according to the water quality, so as to maintain a certain degree of water quality, so that the water body is always in a live and cool state.
