Pump Flow and Water Proportion in koi fish Fish Pond

If it is a fish pond, it is probably 1.5-3: 1. If it is a small or medium-sized fish tank or fish pond, it is about 4-6: 1. Of course, the more water cycles per unit time, the better.

For general stocking of fish ponds, please refer to the koi fish density table for stocking fish ponds; The density of the aquarium is generally 60 cm× 30 cm× 15 cm, and six koi fish with a body length of 15 cm -20 cm can be raised. 90 cm× 30 cm× 50 cm can stock 8 tails; 110cm× 30cm× 50cm can be stocked10 tail.

Koi fish, like goldfish, has no strict requirements on water temperature and water quality. The suitable temperature range is 2℃ ~ 30℃, but it can't resist the sudden change of water temperature and the discomfort of koi fish when the temperature difference suddenly exceeds 2℃ ~ 3℃. The optimum water temperature is 20℃ ~ 25℃. It needs sufficient oxygen and is suitable for living in a slightly alkaline and low hardness water environment.

Four seasons management:

With the change of seasonal temperature, the management methods in koi fish are different.

In spring, when the weather is warm and cold, koi fish begins to recover from hibernation, and the breeding moves from indoor to outdoor, but special attention should be paid to the sudden cooling, covering the film in time to keep the water temperature stable; Plant bait is the main food, and the dosage is gradually increased from less to facilitate the digestion and absorption of koi fish. ?

When the weather is hot in summer, it is necessary to cover the plastic sunshade net to prevent direct sunlight, and it is most appropriate to reduce the sunlight illumination from 8000 ~ 12000 lux to 5500 ~ 5800 lux.

In autumn, the weather is less rainy and sunny, and the water temperature drops obviously, which is most suitable for the growth of koi fish and can increase the proportion of animals (protein), such as silkworm chrysalis. Increase investment and promote rapid growth.

In winter, the weather is cold. When the temperature drops to 0℃, koi fish should be moved to an indoor fish pond for wintering, and the indoor water temperature should be kept at 2℃ ~ 10℃. Pay attention to keep warm, feed properly and prevent diseases. The wintering period in koi fish is 1 1 to March of the following year.
