Matters needing attention in feed formula of koi

Note that fish can easily become big and fat because they love to eat too much. This formula is the most popular feeding formula in Japan at present, with adequate and balanced nutrition and low cost. It is suitable for daily feeding of high-grade fish or surprise feeding of ordinary brocade carp before sale, with quick effect and high efficiency. Once stopped feeding, the fish body changes little. In addition, the absorption capacity of fish to the feed is very strong, the finished product is not easy to disperse water, is not easy to pollute the water body, and will not make the water quality muddy. In spring and autumn, a portion of pig liver and pig blood can be added to strengthen nutrition, which has a special effect on winter, pregnancy induction or reproductive energy storage. The brightening formula is to add 1/1000 of natural astaxanthin on this basis, pay attention to natural astaxanthin or special-shaped astaxanthin, artificial synthesis is also added.

The weather temperature changes greatly in spring, and it is also the season for the recovery of all things. For koi who have just moved from indoor koi ponds to outdoor koi ponds, feeding is very important, and attention should be paid not to emergency feeding. When the weather forecast temperature drops, the fish pond should be covered with plastic film to keep the fish pond temperature stable. When the koi recovers in spring, the physique notes of the koi are weak, and the amount of feeding should be gradually increased, not to be changed at once, and the food digested and absorbed by plants need to be fed.

The water temperature may rise in summer. In order to maintain the normal growth of koi, or to prevent the spread of koi disease and algae, it is necessary to cover the koi pond with a sunshade net and keep it at a constant temperature. if you have the ability, you should set the illuminance at 5500 UV 5800 lux. According to reliable data, it is shown that proper ultraviolet rays are good for the hair color of koi.

The temperature in autumn is not as high as in summer, it is crisp and cool, and the temperature is also very suitable. The water temperature of the fish pond will drop, at this time the water temperature is the most suitable for the growth of koi, you can feed more feed, the net makes the koi full, and choose the feed with high protein content.

The temperature drops obviously in winter, when the water temperature is 0 ℃, the koi swims slowly and eats less. The koi should be transferred to indoor ponds or large koi tanks in time, and the water temperature should be kept at 2 Mustok and 10 ℃. If you want to feed brocade carp properly, don't remember too much.

The majority of fish friends can first try a small amount of this koi feed formula, if the fish can adapt, and the benefits are obvious, why not? In breeding, the most important thing we should do is to reasonably reduce costs to obtain greater profits.
