In the hot summer, the sun shines hot on the earth, and everything is full of vitality and vitality. For koi farmers, this season brings opportunities, but also accompanied by challenges. Summer is a crucial period in koi farming, and we need to pay special heart and attention. Water quality is the cornerstone of the health of koi, summer water temperature rise, water quality is easy to deteriorate, strengthen the operation of the filtration system is crucial, to ensure efficient work, timely cleaning filter material, keep water clear, clean, at the same time, increase the frequency of water change, but pay attention to the smooth transition of water temperature, avoid discomfort to koi, water temperature control is the key, and algae control, feed selection, regularly detect water quality indicators, such as ammonia nitrogen, nitrite, control them within the appropriate range, to create a good living environment for koi.
When farming koi in summer, the following key points to ensure the health and vitality of koi:
1. Ensure sufficient dissolved oxygen:
Koi grows 20% – -30% faster in water with 7 mg/L of dissolved oxygen than in 4 mg/L of dissolved oxygen.When the dissolved oxygen in the water reaches 5 mg/L, the appetite of koi is increased; and the bait coefficient reaches the best. In summer, the water temperature rises and the dissolved oxygen decreases, so the dissolved oxygen supply is increased to prevent the weakening of koi activity, physical fitness and disease resistance.
2. Water temperature control:
Summer sunshine is strong, the water temperature is easy to be too high, resulting to koi “hot tail” and other diseases.
Direct sunlight can be reduced by shading the fish pond or fish tank and stocking aquatic plants (such as water hyacinth, duckweed, etc.). Increasing the water depth can slow down the sharp change in water temperature and provide a better range of motion for koi.
3. Algal quantity control:
In summer, blue and green algae in the water are easy to overproduce and compete with fish for oxygen, causing death from hypoxia.
Too many blue and green algae die in large numbers, corruption decomposition will cause water quality deterioration, resulting in the pool.
Control the quantity of algae in the water body, maintain the quantity of low algae quantity in the water, and prevent the excessive reproduction of algae quantity through water change and dosing.
4. Timely water change:
In summer, koi throw a large amount of food, more feces, excessive organic residues in the water deposition is easy to make the water hypoxia and water quality deterioration.
Timely water change can discharge residue, keep the water fresh, reduce the water temperature, and control excessive algae reproduction.
The water should best be changed in the morning and evening.
5. Avoid rain water from entering:
Rain water is acidic, and a lot of rain into the pond acidifies the water, causing fatal damage to koi.
In thunderstorms, cover the outdoor fish tanks and ponds to avoid rain water.
6. Feed selection:
Summer koi digestive capacity to reach the strongest, can feed the unified staple food, but should pay attention to balanced nutrition.
Feed includes animal feed (such as grasshoppers, earthworms, red worms, etc.), artificial bait, vegetables and fruits, etc.
Feed types and ratios can be adjusted for different growth stages.
7. Disease prevention and treatment:
Summer koi is prone to diseases, mainly caused by parasites and bacteria.
Common diseases are rotten gill disease, printing disease, wheel worm disease and so on.
Keep the water quality stable, regular disinfection and sterilization, timely detection and treatment of diseases.
To sum up, summer koi farming needs to pay attention to dissolved oxygen, water temperature, algae quantity, water change, rainwater, feed selection and disease prevention and control. Only by doing these aspects well can we ensure the healthy growth of koi in the summer.
Finally I want to say, let us on the way to continue firmly, with full of love and responsibility caress them, witness them in every season blossom a charming luster, jointly build a beautiful koi of heaven and earth, let our life more colorful because of them, let the love of koi and persistent continue forever.
