Techniques for management of autumn loach breeding

Regular use of water quality, bottom quality modifier pond bottom of the organic matter content is too much, algae grow vigorously, oxygen consumption, methane, carbon dioxide, hydrogen sulfide, ammonia nitrogen and other harmful substances are more likely to form a polytoxic layer, is not conducive to the normal growth of loach, It is easy to cause muddy over-edge and poisoning. Therefore, according to the condition of the pond bottom, we should select the appropriate water diversion and change the bottom product to improve the bottom quality and water quality environment.

The regular use of oxygen-enhancing particles uses oxygen-enhancing particles in a timely manner to enrich the underlying oxygen, promote the decomposition and conversion of the bottom organic matter, and discharge harmful gases.

Timely change of water timely change of water is beneficial to increase dissolved oxygen in the water, increase the amount of food intake of the muddy, and determine the number of water changes and water exchange according to the color, transparency, and weather conditions of the water. Generally, the water change is performed once every 7 days to 10 days. Water is 1/3 or 1/4.

Reasonable feeding should be based on muddy activities, growth, eating, weather, water quality and other conditions. Flexible control of the amount of feed, let the muddy eat well, but not wasted.

Prevention and treatment of diseases The autumn temperature is moderate, it is the peak season for loach, and it is also the time for pathogenic microorganisms to breed. Loach edema, rotting, skin decay, rotten mouth and other diseases are also suitable for autumn, so we must do preventive work. Never neglect it. Under normal circumstances, every 10 days to 15 days, with iodine or glutaraldehyde 150 ml -200 ml / acre. meters, splashed Quanchiposa, even splash two days. For the feeding of wintering loach on the feed, it is necessary to add liver tyler, overwintering treasure, multi-dimensional, allicin, or florfenicol to prevent the occurrence of various diseases. At the same time, some detoxification and water transfer should be added according to the water quality. The class of drugs prevent toxic substances from damaging the loach.
