Aquarium breeding "heat-removal" method

Aquarium breeding "heat-removal" method

At present, the weather is getting hotter and hotter. The ornamental fish with a good market has also become a bright spot for farmers in the suburbs and counties of this Municipality, but the high temperatures cause great trouble. City aquatic experts warned that after the temperature is higher than normal temperature, it is necessary to pay attention to ornamental fish to “shelve off the heat,” and especially to be alert to the hypoxia of ornamental fish and the threat of “hot-tail”. According to reports, summer is the peak season for the growth and development of ornamental fish. In normal circumstances, it is less likely to get sick. However, after the temperature is higher than room temperature, it is also necessary to “relax” the temperature of ornamental fish in time. According to the person in charge of the Bureau of Science and Education of the Municipal Bureau of Aquatic Products, peasant farmers are required to actively work on the heat preservation of ornamental fish. The main measure is to deepen the water level to 35 to 40 cm, and try to keep the water temperature within 30 degrees Celsius so that the ornamental fish can infiltrate into the lower temperature. The deep "summer". Thorough decontamination, frequent water changes, and the use of shaded nets or drapes can slow down the rise in water temperature, maintain high levels of dissolved oxygen in the water, and inhibit the proliferation of phytoplankton. This is to prevent "floating head" and "hot" of ornamental fish. Tail" is an effective method. In addition, if fish is reared in the open air, it should be completely replaced after rain or water, even if the original pool water is not too old. Because when the water flows into the surface of the fish pond, the temperature of the water is lower than the temperature of the pool before the rain, and the bottom water will rise. In this way, the up-and-down convection causes the dirt in the pool to ups and downs. In severe cases, “floating head” or “stirring cylinder” will appear. ".
