Feeding of red fin crucian carp

According to the requirements of red fin crucian carp for feeding containers, aquatic plants and gravel, the water temperature and pH value of the feeding water should be prepared for fish culture.

After buying red-fin crucian carp, put the plastic bag containing red-fin crucian carp directly into the fish tank to adjust the water temperature 10-20 minutes, and then open the bag to let red-fin crucian carp enter the fish tank with the water. Next, the red fin crucian carp will be carefully raised and managed. Feeding must follow four principles: timing, fixed point, qualitative and quantitative. Generally speaking, it is more appropriate to feed the compound feed twice a day, at 9: 00 am-10: 00 am and at16: 00 pm-17: 00 pm. Live bait such as fish worms can be fed at once in the morning. For larvae, it is necessary to ensure that there are open bait such as rotifer, paramecium or egg yolk in the tank. Pay attention to put the earthworm in a perforated plastic box and hang it in the water when feeding it, so that the fish can eat freely. If you feed other chopped animal bait, you should feed it in a "hanging basket". Feeding should have a fixed position, so that fish can concentrate on eating and reduce waste; The bait must be fresh and free from spoilage; The feeding amount should meet the needs of fish growth, and there should be no extra nutrition. According to the situation of fish in the box or pond, the daily feeding amount is generally 2%-4% of the total weight of fish, and the comprehensive judgment is based on eating 30-60 minutes after feeding.

When feeding, it should be increased or decreased according to the seasonal climate characteristics, water temperature and water quality differences and the feeding intensity of red fin crucian carp. It is forbidden to throw more or less at will, or not to throw for several days or throw together for several days. During rainy days, cooling, sultry weather and illness, try to throw less or not. If you can't feed it every day when you go out, feed it normally, and change the water before you go out to ensure clear water quality and sufficient oxygen. Hunger for a few days has no effect on the health of fish. Don't feed it for a few days and it will cause the red fin crucian carp to die. 1, spring

The focus of management is correct feeding and disease prevention. The climate is getting warmer in spring, and the red-fin crucian carp after wintering begins to move, but its constitution is relatively weak, so the feeding amount should be gradually increased. Due to the great climate change, we should pay special attention to keep warm in case of wind and rain. In spring, bacterial viruses also multiply rapidly, and fish diseases are the most popular. Attention must be paid to the prevention and treatment of diseases.

2. Summer

Red-fin crucian carp grows in the peak season, the water temperature is usually above 22℃, and red-fin crucian carp rarely gets sick. If the bait is sufficient and the water is changed frequently, its growth is better than other seasons. The demand for oxygen is increasing, and preventing water from being deprived of oxygen becomes the key to feeding. Reduce stocking density, frequently change water and discharge sewage, and pay attention to increasing oxygen, especially in muggy and shanghai dawn.

weather Less bait and more bait. Pay attention to heatstroke prevention and cooling, and cover the water surface of 1/3- 1/2 with bamboo curtain to prevent "tail burning" accident. 3. Autumn

The focus of management is hello, hello. Appropriately increase the proportion of nutrients such as fat and protein in feed. The weather is getting colder in late autumn, so the feeding should be gradually reduced. At the same time, gill rot, leukoplakia and dermatomycosis are also easy to break out, so it is necessary to prevent fish diseases.

4. Winter

The key point of management is to keep cold and raise correctly. The heating equipment in the greenhouse or aquarium makes the water temperature generally not lower than 20℃. Or use the function of residual hot water in the factory to maintain a suitable water temperature for normal breeding and reproduction. Prevent fish from getting sick or freezing to death due to sudden drop of water temperature (especially at night).
