January: The cold weather this month is the coldest season of the year. Goldfish should be kept warm. If conditions permit, the goldfish can be moved to winter indoors or in the greenhouse to minimize water quality changes. The feeding work is concentrated at noon. . February: In late February, the temperature gradually warmed up, strengthening the investment of goldfish. The water quality is generally changed once every 30 days. Select broodstock, reduce the stocking density, strengthen the broodstock to fatten up, and make good preparations for the breeding of broodstock. March: The average temperature in the south of the Yangtze River in March is around 10°C. Sometimes the temperature will be higher than 20°C. As spring temperatures begin to rise, the rate of organic matter corruption in feed water is significantly accelerated. In case of severe southeast winds on several days, when the temperature rises significantly, the wintering old water of ornamental fish should be promptly replaced to prevent hypoxia. In the latter part of March, the gonads of ornamental fish are already mature. If the water temperature is increased with a greenhouse at this time, the goldfish will reproduce in advance. When the weather is fine, different species of broodstock are kept separately in a fish pond in a certain proportion to prepare for nesting. In April: Before and after Ching Ming Festival, ornamental fish enter the breeding season. The focus of work should be shifted to broodstock care and hatching of fish eggs. Spawning broodstock is more stable in light green water. When there is estrus, it will be replaced by spawning in new water. Observe the activities of the broodstock every morning and put it into the fish nest in time. At the same time, the hatching of fish eggs and nursing of larvae are done. In May: It is the prolific breeding of ornamental fish in the Jiangnan region. Properly arrange broodstock, do the second and third spawning work for broodstock, and strengthen feeding and water quality nursing for broodstock that have not spawned yet. For juvenile caudal fin bifurcation, change the water and select in time, usually about 7 days for water change. May is the season of goldfish rot disease, broodstock should be kept in green water as much as possible to reduce the number of water changes, so that the broodstock to maintain a healthy state into the rainy season. June: Most of the south of the Yangtze River enter the rainy season, which is also the annual season of ornamental fish. In case of rainy weather, it is necessary to regularly conduct liquid spillage and water conditioning on a regular basis, especially in the days when the weather is hot and humid. We must also pay attention to observation and timely treatment of water quality to prevent the goldfish from prolonged periods of mild hypoxia and cause discomfort. , and then induce disease. June juveniles have entered the color transformation stage, pay attention to nutrition, do a good job screening of juveniles. July: It has entered the hot season. The average monthly temperature is around 25°C. The focus of work at this time is to prevent the heatstroke and hot tail of the goldfish, and to improve the water exchange. Occasionally, high temperatures of 35°C will occur in July. Pay attention to shading in fish ponds. The feeding of goldfish is mostly concentrated in the morning at 7-8 in the morning, and the water quality of the goldfish is changed once every 4 to 5 days. Most juveniles of goldfish have entered the late stage of screening, and the stocking density should be adjusted in time to enhance the fattening of young fish. August: It is the month with the highest average temperature in a year. Deepen the water level in the open-air fish ponds. The focus of work is to strengthen heatstroke prevention. Observe the phenomenon of hot-tailing of goldfish and the floating-head condition of the middle of the night. If necessary, replace the water for 2-3 days. once. The amount of goldfish feeding should be controlled at 7-80%, to avoid the residual bait remaining in the water, and the residual bait will cause water quality deterioration. Strengthen the observation work in the middle of the night to prevent the death of goldfish due to lack of oxygen and death in the whole tank. September: In early September, it is still hot weather. After the end of September, the temperature gradually decreased. The emphasis of goldfish rearing is to strengthen the fattening and increase the amount of feeding. The water quality is generally changed every 7-10 days, to strengthen the disease prevention of ornamental fish, control the feed water to transform from clear water to green, stabilize the body condition of goldfish, and strengthen the fattening of goldfish. October: The climate is getting cooler, and the water quality of goldfish is changed about once every 15 days. When changing the water, the balance between the old and new water temperature should be maintained. The open-air fish pond can properly lower the water level. October is the second epidemic season of ornamental fish in a year. Attention should be paid to drug prevention, and the goldfish's fattening work should be strengthened to lay a good foundation for wintering of goldfish. In November, the temperature gradually cooled, the water temperature was about 10°C, the goldfish’s appetite was normal, and the water quality changed about once every 20 days. When changing the water, pay attention to the balance between the old and new water temperature. Ornamental fish should be kept in green water as much as possible to strengthen the diseased individuals. medical treatement. In December, the temperature dropped, and the focus of work this month is on the cold and warmth of goldfish. The appetite of goldfish is obviously reduced. The water quality is changed about once every 30 days or so, and the feeding work is delayed until around noon. The stocking density of fish ponds can be appropriately increased. The water color is dominated by green water, and the water level in the open pond needs to be properly deepened.
