How to raise fish in different solar terms?

January and February (from the beginning of spring rain):

1, beginning of spring: On February 4th or 5th every year, after the solar term-beginning of spring, it marks the beginning of spring, and all kinds of fry begin to be released until the end of March in the solar calendar; Common diseases of fish: cold and frostbite. At this time, the water temperature is low and fish diseases are few. After the pool is thawed, it should be disinfected properly to adjust the water quality. 2. Rain: February 19 or 20 every year, solar term characteristics-indicating that the weather is getting warmer, the precipitation is gradually increasing, and the temperature is changing from cold to hot, which is one of the seasons with the most cold waves in the whole year; Fish don't eat before it rains, and they are still in hibernation, which is a good season for releasing fish species in the Central Plains. Common diseases of fish: cold and frostbite. At this time, attention should be paid to the disinfection when the ice and snow in the pond melt. February and March (spring equinox): 1, fright: the characteristics of solar terms on March 4 or 7 every year-everything begins to recover, trees begin to spit green, the temperature begins to rise to about 15 degrees, and the water temperature is about 10 degrees, which is also a good time for fry release, and carp and crucian carp ponds can start. Common diseases of fish: bubble disease, pox disease, scale disease, water mold and cold, so be careful not to damage the fish when releasing seedlings, and the disease is mainly to prevent water mold; 2. Equinox: On March 20th or 2 1 every year, the characteristics of solar terms-the severe cold gradually recedes, the daily average temperature rises above 10 degrees, fish species are basically released, fish ponds are gradually fed, and food intake is gradually increased. After the vernal equinox, the pond must be changed, otherwise the fish will die easily; Common diseases of fish: gill rot, enteritis, acne, scaling, water mold, anchovy. With the increase of temperature, fish diseases gradually increase. March and April (Qingming, Grain Rain): 1. Qingming: On April 4th and 5th every year, the characteristics of solar terms-the weather is sunny and warm, and the vegetation turns green, but the weather changes greatly. Generally, there is cold air coming, and the temperature will drop obviously. The release of fish species has basically ended, the temperature has risen, silver carp can no longer be transported for a long distance, bighead carp is slightly better, fish in ponds and cages have begun to eat, and tropical fish can not be normally stocked outdoors; Common diseases of fish: gill rot, enteritis, acne, scaling, water mold, anchovy. With the increase of temperature, fish diseases gradually increase. 2. Grain Rain: Every April 19 or 2 1, the solar term features-the last solar term in spring, the cold wave weather basically ends, the temperature rises rapidly, and the fish grows rapidly; During the Qingming snow break and the Grain Rain frost break, tropical cultured fish can start to be released outdoors; Other fish began to eat energetically; Common diseases of fish: gill rot, enteritis, acne, scaling disease, water mold, anchovy, eosinophilia, rotifer and carp are prone to gill rot, enteritis and hemorrhagic septicemia. Fish intussusception began to occur, water mold began to decrease, and grass carp ring disease occurred seriously.

April and May (long summer, small full):

1, Long Summer: On May 5 and 6 every year, the characteristics of solar terms-bid farewell to spring and summer, the temperature rises obviously, reaching more than 30 degrees, and thunderstorms increase; After crucian carp and carp basically lay eggs and hatch, there will be no more water mold infected by transportation, fish will grow rapidly, thunderstorms and rainy days will increase, and fish will float and die in the pond. Oxygen-increasing equipment is installed in place, pay attention to oxygen-increasing; Common fish diseases: gill rot, enteritis, erythroderma, acne, scaling disease, anchovy, third generation worm, giant salamander, cucurbitaceae, rotifer, carp prone to Baiyun disease, sporozoa and grass carp hemorrhagic disease began to spread in a large area. 2. Xiaoman: On May 2 1 or 22 every year, the characteristics of solar terms-summer is gradually entering all parts of the country, and the temperature difference between north and south is further narrowed; Splash fry of all kinds of fish began to be cultivated, outdoor culture of tropical fish was no longer affected by temperature, hemorrhagic disease of grass carp began to slow down, and the number of dactylogyrus and third generation worms began to decrease. Common diseases of fish: gill rot, enteritis, erythroderma, acne, vertical scale disease, anchovy, third generation worm, giant salamander, cucurbitaceae, rotifer, sporozoa and grass carp hemorrhagic disease. May and June (awn seed and summer solstice): 1. Miscanth seed: On June 5th and 6th every year, the temperature of solar terms, which is a feature of solar terms, continues to rise, and can rise to above 35 degrees. After crucian carp and carp summer flowers are released, pay attention to the lack of oxygen in the pond at this time, and the management is easy to be careless and flood the pond; Common diseases of fish: gill rot, enteritis, erythroderma, acne, vertical scale disease, anchovy, third generation worm, giant salamander, cucurbitaceae, rotifer, sporozoa and grass carp hemorrhagic disease. 2. Summer solstice: June 2 1 or 22 every year, the characteristics of solar terms-sultry weather, rainy days, plenty of rain, rapid growth of red worms in the pond, easy to cause hypoxia floating in the pond, fish eating vigorously, grass carp prone to hemorrhagic disease and death; Common diseases of fish: gill rot, enteritis, erythroderma, acne, vertical scale disease, anchovy, third generation worm, giant salamander, cucurbitaceae, rotifer, sporozoa and grass carp hemorrhagic disease. June and July (light summer heat and heavy summer heat): 1, light summer heat: July 7 or 8 every year, the solar term features-the beginning of hot weather, rising temperature and water temperature, all kinds of fish eat vigorously and grow rapidly, and the sales of summer flower fry are basically completed, and the splash fry of that year has become inch by inch. During this period of high temperature, there are few third-generation insects and dactylogyrus. Common diseases of fish: gill rot, enteritis, erythroderma, acne, scaling disease, anchovy, third generation worm, giant salamander, cucurbitaceae, rotifer, sporozoa, grass carp hemorrhagic disease, trypanosoma and cryptocaterpillar. 2. Great Summer: On July 22nd or 23rd every year, the solar terms are characterized by the highest temperature, more thunderstorms, frequent high-temperature weather above 40 degrees, high temperature and high water temperature, attention should be paid to oxygenation to prevent floods, fewer third-generation insects and dactylogyrus, and rapid growth of inchworm species; Common diseases of fish: gill rot, enteritis, erythroderma, acne, scaling disease, anchovy, third generation worm, giant salamander, cucurbitaceae, rotifer, sporozoa, grass carp hemorrhagic disease, trypanosoma and cryptocaterpillar. July and August (beginning of autumn, early summer): 1, beginning of autumn: August 8 and 9 every year, the characteristics of solar terms-the weather is slightly cool, the temperature is high during the day, the temperature difference between morning and evening begins to increase, the third generation of insects and dactylophora begin to spread for the second time within one year, and the annual grass seedlings begin to break out with hemorrhagic disease and die seriously; Common diseases of fish: gill rot, enteritis, erythroderma, acne, scaling disease, anchovy, third generation worm, giant salamander, cucurbitaceae, rotifer, sporozoa, grass carp hemorrhagic disease, trypanosoma and cryptocaterpillar. 2. Summer: On August 23rd or 24th every year, the solar term is characterized by hot weather, more rain, ending ventilation, obviously hot weather during the day, cool in the morning and evening, further widening the temperature difference between day and night, and the temperature begins to drop, but oxygen is indispensable. Although the autumn wind is strong, don't covet to save electricity and turn on the aerator. Hemorrhagic disease of grass carp is serious, and hemorrhagic disease of annual grass species is prevalent. Common diseases of fish: gill rot, enteritis, erythroderma, acne, scaling disease, anchovy, third generation worm, giant salamander, cucurbitaceae, rotifer, sporozoa, grass carp hemorrhagic disease, trypanosoma and cryptocaterpillar. August and September (white dew, autumnal equinox): 1, white dew: September 7th or 8th every year, solar term characteristics-the weather is getting colder, the temperature difference between day and night can reach more than 10 degrees, most of them have dew during the day, the temperature is suitable, the fish grow faster, and the fish pond begins to fog at night, so it is necessary to start the aerator, the third generation worm and the ring. Common fish diseases: grass carp hemorrhagic disease, third generation worm, dactylophora, gill rot, enteritis and rotifer. 2. Autumnal equinox: On September 22nd or 23rd every year, the characteristics of solar terms-short days and long nights, further increase the temperature difference between day and night, and enlarge the scope. Cold air began to invade and slowly entered the late autumn. When the temperature is right, the growth speed of fish is accelerated. Therefore, tropical fish breeding should pay attention to the growth situation and seize the opportunity to sell as soon as possible. Common diseases of fish: grass carp hemorrhagic disease, third generation worm, giant salamander, gill rot, enteritis, rotifer and anchovy. Nine, 65438+1 October (cold dew, first frost):1,cold dew: 65438+1October 8, 9 solar terms every year-the rainy season ends, the days are warm and the nights are cool, the temperature drops below 25 degrees, and the water temperature is about 20 degrees. In the southern region, it is still the peak season for fish growth, so it is necessary to turn on the aerator frequently. However, for fish ponds with a large amount of fish, the aerator should be switched on and off according to the weather conditions, especially for fish ponds with deep water level (the water level is above 2~3 meters). In bad weather, the vertical convection of water will lead to water diversion, resulting in hypoxia and a large number of dead fish. Pay attention to observation and prevention. After the cold dew, fish can be transported for a long distance, and tropical fish should be sold quickly. Common diseases of fish: fish diseases gradually decrease, hemorrhagic outbreaks, third generation worms, dactylophora, rotten gills, enteritis, rotifer, anchovy, cucurbitaceae, hepatopancreatic septicemia. 2. First Frost: Every year1October 23rd or 24th10th solar term features-the last solar term in autumn, the weather is getting colder and frosty, and the temperature drops obviously. There is still some waste heat in the south during the day, the temperature is suitable, and the fish grow fast, so it is necessary to feed enough to breed. However, cold air began to invade frequently. When the cold air comes, the water temperature on the surface of the fish pond will drop sharply, which will lead to serious convection in the pond and lead to flooding and death. The average temperature in the north dropped to about 16 degrees, and the fish's food intake decreased a lot, but it is not appropriate to stop eating. It is necessary to extend the feeding time as much as possible, increase the nutrition of fish and prepare for winter. Common diseases of fish: fish diseases are gradually decreasing, but we should pay attention to the outbreak of melons and rotifers, and prevent the occurrence of Trichosanthes in water quality control. X. 165438+ 10 month (xiaoxue, beginning of winter): 1, beginning of winter:165438+1October 7 or 8, the characteristics of the annual solar term-entering late autumn, starting in winter, fish are ready to hibernate. When the water temperature is about 12 degrees, a small amount of feed should be given on sunny days to strengthen the status of cultured fish before overwintering and enhance their cold resistance during overwintering. Whether in the south or the north, it is best to add medicinal materials to the feed before stopping feeding, so as to prevent and control the scale disease of carp and crucian carp during the wintering period. Common diseases of fish: vertical scale disease, small melon worm and snapper. 2. Xiaoxue: Every year,1October 22nd or 23rd, 165438+ Due to the characteristics of solar terms, the temperature keeps decreasing, but the weather is not too cold. The northern region has begun to freeze, but it will not become thick and frozen, and there are few diseases in cultured fish. Common diseases of fish: fish diseases are rare, but cucurbit fish, anchovies and microalgae are easy to appear in greenhouse culture. Eleven, 65438+February (heavy snow, winter solstice): 1, heavy snow: February 7 or 8 every year, 65438+February, solar terms characteristics-the weather temperature is low, the temperature in the south is around 10 degrees, and the temperature in the north is basically above 0 degrees. To prevent the pond from freezing, pay attention to prevent the pond from suffocation due to lack of oxygen. Common diseases of fish: Cephalotaxus aurea and stagnant pool. 2. Winter solstice: February 22nd or 23rd every year 10, the characteristic of solar terms-the temperature keeps dropping, so count to nine. The management of fish ponds is the same as above. 1 February 65438+1October (slight cold, severe cold):1,slight cold: 65438+1October 5 or 6 every year, with solar term characteristics-strong wind and low temperature. The management of fish ponds is the same as above. 2. Severe cold: about 65438+1October 20th every year. The solar terms are characterized by strong wind and low temperature, and the management of fish ponds is the same as above.
