Summer Fish Keeping Precautions and Daily Management Points
The main thing to pay attention to when keeping fish in summer is the influence of weather. Weather can lead to the appearance of certain situations, and these are what should be noted. How to prevent such phenomena from happening, and what to do if the following phenomena occur. How to handle them. What are the common situations in summer that are unfavorable to fish growth? Please continue reading the content below, and we will list and introduce them in detail.
1. Increase Feed
After the weather becomes hot, the water temperature also rises somewhat, and fish move frequently in the water, so they first consume a great deal of energy, and nutrient metabolism is very fast, so nutrients must be supplemented in time. The feed given will increase, and the number of feedings can also be increased, as can the feeding amount, but all amounts should be what the fish can finish within one hour. This avoids the fish experiencing hunger.
2. Maintain Water Quality
A pond holds a large amount of water, and generally it is in a state of continuous inflow and outflow of living water, so it is still quite capable of storing some water. After water has been stored for a long time, the nature of the water is prone to change, and slightly alkaline water may become acidic water. This is unfavorable to the growth of some small organisms, and the fish are then less able to catch natural food. Therefore, lime is sprinkled once a month, about 0.375 jin of lime per mu of land.
3. Increase Oxygen
When too much algae grows in the water and covers the water surface, the fish in it are very likely to lack oxygen. Also, if too much feed is put in, it affects water quality, or if the water temperature is too high, oxygen deficiency in the water will occur. Therefore, an aerator must be used to increase oxygen in the water. Clean the pond in time, pull out the algae with extremely strong reproductive capacity, and finally replace the pond water, and the oxygen environment will improve.
4. Control Temperature
In summer the temperature rises, and strong light absorption of heat occurs. The temperature most suitable for fish growth is around 20-plus degrees, and temperature affects the fish's appetite, causing their growth to slow down. In summer the temperature often easily reaches 30-plus degrees, so shade nets can be used to shade the pond. Or change a small amount of water to neutralize the water temperature.
5. Eliminate Algae
Some algae can be eaten by fish, but some are toxic to fish, and their reproductive capacity is astonishing, making it very easy for them to cover and pollute the pond. In summer their growth vigor is better and they grow faster. Therefore, algae must be cleaned and salvaged in real time, and removed promptly when it first appears, using copper sulfate to eliminate it.
Keeping fish in summer is mainly about regulating the fish's growing environment. The key is temperature control and increasing feed, maintaining good growth. You cannot let summer weather conditions affect fish growth. The main purpose is to let fish still grow and develop in summer.
