How long will the fish shed after the lime is put off?
In addition, 10% to 20% of the amount should be added to the ponds with thicker sludge and thicker water color. The thin water color lighter, less per 667m of phytoplankton, the water depth of 1m - quantity can only be below 10kg.3, a timeGeneral full time in the sunny afternoon splashing pool should be 3, but in the summer temperature of 30 degrees Celsius above, deep pool 1m small pond, the pond sprinkle lime carefully, if the weather changes is very easy to cause the water quality changes and fish. Also, not all hot, thundershowers pool sprinkle lime, otherwise will cause the next morning hypoxia pan pool. In addition, before the river crab, shrimp shell should be appropriate to sprinkle lime water, can increase the calcium ion in water, improve water alkalinity, is conducive to the growth of shrimp and crab shell.Note: Lime should be prepared when using, to prevent the precipitation reduction; lime should be used with caution in high ammonia nitrogen content of the water splashing; before the partial replacement of water; it should be divided, small, many fish splashed; outbreaks of infectious diseases, using lime, and the choice of drugs in response to disease treatment. To avoid delays in treatment.
(1) since the dose: pond with water (1m water depth) per 667m - 150kg, lime water after the opening of the pool splashing. Dry cleaning (10cm water depth) per 667m - 75kg, lime water after the opening of the pool splashing. Special reminder: it is best to use block lime, it can emit a lot of heat energy, and should be immediately used, placed too long will reduce efficacy. Water hardness, bottom mud, lime pondthe will effect, should be appropriate to increase the amount of. Lime pond drug generally after 5 ~ 7 days away, put the fish before the test.(2) when the dose of prevention and treatment of fish diseases: lime dosage for each 667m2 water depth of 1m preventing disease of 13 ~ 15kg, 15 ~ 20kg treatment of fish diseases, but the treatment of hemorrhage in 25 ~ 30kg of crucian carp. Observe the reaction of the fish after taking the medicine, in case the dosage is too large and the water quality changes suddenly, resulting in dead fish.
General fishpond fish feeding, vigorous growth, often sprinkle lime is better; the new dig ponds without bottom silt, the buffer capacity is weak, lack of organic matter, should not use lime, otherwise it would be exacerbated by the limited decomposition of organic matter, water and nutrient deficiency. The pH value of the water in the lower pond, to sprinkle lime to adjust the pH value of water; and the higher the pond of excessive calcium, is not appropriate to use lime, otherwise it will make the phosphorus concentration in water decreased, causing water phosphorus deficiency, affecting the normal growth of phytoplankton.
Lime pond drug generally after 5 ~ 7 days.Quicklime is one of the common disinfectants used in fish farming and livestock farming. It is alkaline, and water disinfection can regulate water PH, increase the permeability of water bodies, increase dissolved oxygen in fish ponds, and promote fish ponds to increase production. However, the lime pond disinfection has many restrictions, farmers in the use of, for Tang system, pay attention to the use of time and dose, a disinfection taboo.
