All life activities such as activity, food intake, growth rate, and reproduction of goldfish vary with the seasonal climate. Therefore, there are different management methods for keeping goldfish in different seasons.
(I) Management in Winter The temperature in winter is relatively low. After winter in the north, when the water temperature falls below 6°C, the metabolism of goldfish is at a low point. When the temperature drops to 0°C, it begins to freeze. If the outdoor fish pond is not treated with insulation, it is generally sealed by the ice. If the ice is thick, it can easily make the goldfish suffocate by not breathing oxygen. After the ice, it is necessary to pick up an ice hole in the center and let the air enter the water body. Pit ponds should have a portion of deep water. After the ice is built, there will be 1 meter of colorful bodies of water under the ice. The goldfish can spend the winter in the deep water area. If it is a small fish pond, it is usually controlled by thermal methods. Outdoor breeding of goldfish, in the north do not generally need to change the water and feeding; indoor breeding of goldfish, according to the indoor temperature situation to manage, room temperature below 5 ~ 6 °C, the goldfish is in a dormant state, you can not feed without water, To achieve the purpose of safe winter goldfish can be. However, it is not cost-effective to do so. In the same amount of manpower, material resources, and space, it is better to raise the temperature to about 15~16°C so that the life of the goldfish can be normally and slowly performed at a low temperature. The goldfish can also grow and develop in the winter and promote the early maturation of the gonads. They can lay eggs and hatch early after winter, so that the next generation of goldfish will increase the growth time and win the opportunity for large-scale goldfish.
If the room temperature is controlled above 16°C, the metabolism of goldfish is relatively strong, and the food intake is also high. At this time, attention should be paid to the hygiene and water exchange of the water quality, and attention should be paid to indoor ventilation, otherwise the fish can easily become ill.
(B) management of early spring goldfish after a low temperature in the winter, the body consumed a lot of fat, body more than thin, more resistant to disease, so this season should pay attention to the work of nursing goldfish. For example, when changing water or other operations, you must not hit the fish and put it in a proper amount. After observing the fish's diet, decide on the next feeding amount, and remove the bottom dirt in time to keep the water fresh. Although spring is the season when the earth is spit green, cold air and warm air may come and go irregularly from time to time. The temperature changes rapidly, and the temperature difference between day and night is also large. If the outdoor fish pond is too cold at night, it should be properly protected. This season is a difficult time for fish farming.
(3) Management in summer In summer, the fish's bait is very rich, and the water temperature is relatively high, which is the season when goldfish grow most vigorously. However, the high temperature will also bring certain adverse effects on the life of goldfish. For example, the pool water temperature is too high, the decomposition of various organic substances in the pool is accelerated, and the quality of water quality is reduced, which affects the normal breathing of the fish. In the season when the temperature is higher, the density of the culture should be relaxed and the water should be changed frequently to solve the problem of lack of oxygen. For example, when there are too many green plants in the water, some of them are replaced by water changes or filtration. Otherwise, if there is sufficient sunlight, supersaturated oxygen is produced in the water, and many bubbles attach to the fish body for a long time and cause skin ulceration. At night, after the plant stops photosynthesis, it consumes oxygen in the water, causing oxygen in the water. The goldfish will be forced to breath oxygen in the air because of difficulty in breathing, and the goldfish will die from “floating head†to “boring cylinderâ€.
During the summer season, the weather was changeable. Before the thunderstorm, the weather was sultry. After sudden rainfall, the water temperature on the surface of the fish pond suddenly dropped. The water temperature at the pool bottom was high. Due to the difference in temperature, water up and down convection was caused. As a result, some of the dirt on the bottom of the pond floated up. Before the thunderstorm, it is necessary to clean up the bottom dirt or enhance filtration. In the north there is hail weather, shallower fish ponds need to be strengthened, one fish is easily injured, and when the two ice cubes enter the fish pond, the temperature of the water is reduced. If too much is dropped, the fish is susceptible to disease or sudden death.
Filters and utensils should be sterilized frequently during the summer, and the instruments used for diseased fish must be disinfected in a timely manner to prevent the spread of pathogens.
(IV) Management in autumn Most of the time in autumn, the water temperature and temperature are suitable for the life of goldfish. The food is also rich, and the appetite for goldfish is also strong. It is the best season for the growth and development of goldfish. In order to safely survive winter goldfish, more food should be added at this time, and the content of protein and fat in the food ingredients should be increased, so that the goldfish will grow up and meet the winter season. In the early autumn, the temperature did not change much, and it was necessary to properly shade and change the water. In late autumn, the temperature changed greatly, and the temperature difference between day and night was very different. In the northern regions, it was necessary to prevent cold and prevent frost in advance. When changing the water in the autumn, we must pay more attention to the difference in water temperature, and the number of water changes should be reduced.
