2. Some gramineous plants (such as perennial ryegrass and reeds). ) can be planted around the disinfection pool in Qingtang, about 1 cm away from the shore, which is also good for water quality cultivation. Before the seedlings enter the pond, clean and disinfect the pond with quicklime (150Kg/ mu). When the water in the pond is green, the seedlings can be put in.
3. Feeding of Misgurnus anguillicaudatus fry In general, the stocking density of Misgurnus anguillicaudatus fry should be 800- 1000, and it can be increased appropriately if there is running water. Note that the same batch of loach fry with the same hatching specifications should be kept in the same pond to ensure the balanced growth of fry and improve the survival rate.
4. Feed loach seedlings. Just feed some digestible concentrated feed such as cooked egg yolk, bean powder and bean cake to those who just got off the pond. When the seedlings grow to 1cm, they can already prey on insects in the water. At this time, you can feed some cooked wheat flour, chaff, chopped fish, shrimp and other feeds 3-4 times a day. In addition, when the water temperature is lower than 10℃ in winter, it is not necessary to feed loach. At this time, the depth of the pool water should be appropriately reduced, or a layer of straw should be laid at the bottom of the pool after the pool water is drained, so that the loach can safely overwinter.
5. Water quality control When loach species first enter the pond, the water depth of the pond is kept at 10-20cm. Later, with the growth of loach species, the water level gradually deepened to its due depth, which was shallow at ordinary times and deep when it was hot and high temperature, and new water was often injected to maintain a good water environment. If it is found that loach swims to the surface and spits air, it should be injected with fresh water in time or take measures to increase oxygen.
6, scientific capture Because the loach is small in size and has the characteristics of drilling mud, it is difficult to capture. According to the other characteristics of loach, the following three methods can be adopted: one is to catch loach by flushing, that is, put the grab at the water inlet and then put the water into the pool. Misgurnus anguillicaudatus is stimulated by flowing water, and it is clustered in the upstream of the flowing water and near the water inlet. At this time, the preset net is pulled up, and the loach can be captured; The second method is trapping, that is, putting cooked beef and sheep bones or fried rice bran, wheat bran and other bait into a net or fish cage to attract loach with its fragrance; Third, the dry pond method When the water temperature drops to 15℃- 12℃ in winter, the loach will drill into the bottom mud of the pond and can only be caught in the dry pond.
