Gold carp
Department of goldfish carp (grass) the most primitive varieties of goldfish, common carp similar shape. Main feature is long and narrow body was streamlined, small eyes, a single tail fin, swimming fast, but not afraid of people. After the long-domesticated, can call with the sound of people lined up the tour, throwing food often fought over the water cluster. According to the different color, divided into Penni_set_um crucian carp, golden carp, crucian carp, into the dark, yellow and black carp, white and red carp and other varieties.
Golden carp better than raising goldfish. More primitive gold carp, goldfish, golden carp evolved from over.
1, feeding: feeding are nutritious animal feed and white sesame seeds. Animal feed, such as water fleas, worms, Tenebrio, caterpillar, skin and other insects. Feeding is mainly earthworms and white sesame seeds. Red, black worms can be fed. Do not feed the poor quality of purchased feed goldfish. Because too much starch diet, poor nutrition, not digestible, easily contaminated water, malnutrition, eating goldfish, goldfish relatively slow growth, but also easy to get sick. Goldfish as long as the food is easily digestible food is not Chengsi's. When feeding, usually every morning and afternoon time, it is not appropriate to feed, to eat up so far. Otherwise, pollution, water quality.
2, light: the best place to fish tanks have 1-2 hours of sunlight place. This use of the sun's ultraviolet light disinfection. Play a role in disease prevention. This can reduce the disease. As far as possible fish disease prevention, drug supplement. At the same time, due to photosynthesis, the fish's color is bright and beautiful.
3, changing the water: to frequently change the water, can increase the dissolved oxygen in water. Changing the water when the only change to one-third to one quarter, can not suddenly change to a lot of fish are not suited. To maintain clear aquarium water is essential. Adequate dissolved oxygen in the water the fish can grow long fast. Otherwise, stop growing, or even death. When changing the water, no conclusion can be based on water quality, water quality more turbid change, or little change.
(B) of the bait
1, animal feed
(1) water flea: commonly known as fish and insects. It is the section to be tie down branches moving lutetium trouble fright sigh night embedded spear n flex saddle blanket Yin Zhi jealous resentment favorite Canadian? 00 species, body color with brown, red brown, gray, green and so on. Seasonal growth of fish and insects, have divided Even summer insects and winter worm. Even summer insects before and after the large population of the Ching Ming Festival, blood-red body color, the larger individuals, a larger number of high nutritional value, They live in the river can flow. Small number of insects in winter, body color schungite, low nutritional value, They live in still water ponds or lakes. Fish and insects are the main food of freshwater aquarium fish, goldfish and tropical fish life of an inferior race for food.
(2) Water Earthworm: filariasis, also known as red, red worm, is a part of the aquatic animals, few hairs, red or blue gray in color. They live in river basins of the shore or river of sludge, and sludge density surface, one end fixed in the sludge, the end of the birth of sludge in the water quiver, an encounter alerted immediately retracted the sludge. High water, the nutritional value of earthworms, fed again before rinsing in water, it is a very favorite goldfish and carp bait, eel is the main bait. Shanghai Huangpu River in the river at low tide, the shore of a large number of raw water sludge worms, the annual spring fishing season, some people are a lot of bashing.
2, plant food
(1) Wu Ping: Ping, known as non-root, large sp, which is wandering perennial plants, many years of living in still water ponds or rivers. According to relevant information, including dry Wu Ping, 45% protein, also contains a variety of vitamins and trace elements cobalt, supporting freshwater fish bait. The annual game, when the fish and insects lack, Wu Ping, often as a substitute food.
(2) Chlorella: Chlorella bright green body color, the individual resembles the north millet and capsules seem small grain size, with higher protein, fat, vitamins and trace elements, nutritional value, is the goldfish good green feed, such as mixed feeding and animal feed, which can effectively promote the rapid growth of fish. Chlorella more people live in still water pond or river, they are more mixed Wu Ping, the growth of Chlorella growth alone is relatively rare in natural waters.
(3) planktonic algae: planktonic algae there are many different golden algae, yellow algae, dinoflagellates, diatoms, naked algae, green algae, cyanobacteria, etc., some of which are fish food aid. According to the information can be used to contain or blue water, green water algae feeding fish, the effect is also very good. zy5x

C) the feeding and management
Goldfish, koi feeding and management is a multi-technology integrated projects, which includes feeding, water changes, daily observation; in fish larvae stage, adulthood, broodstock stage, old age, requirements are not the same; in throughout the year, also have different management points.
1, feeding equipment
(2) concrete ponds: cement tank system is made with brick or concrete, walls, smooth concrete bottom with yellow sand, the size of casual, current common pool area of 10 square meters, 16 meters, 25 meters, etc., it is the goldfish, The main container Koi farms.
(3) Aquarium: aquarium is the use of glass which is made by engineering silicone adhesive, is when the common backyard breeding containers. It is crystal clear, the fish's every move, smile for a frown, panoramic view. Aquarium fish with the equipment needs: oxygenation pump, inside the loop filter, heating pipe, fishing nets and so on. There is also a small backyard container oval fish tank, which is specially treated glass blown. It is small and can be placed on the coffee table or desk, easy to move by putting a few plants or a few tablets of stone beams, viewing 也好.

(1) Seeking Habits Bait: Goldfish are cold-blooded animal, all its activities are closely related to changes in water temperature. Goldfish most of the activities to find bait in the water foraging, they live in peace, not occupy the site of the habit. In the goldfish farms, dawn, common goldfish feeding along the edge of the pool. When officers approached the feeding, they will travel to shoot straight forward, commonly known to beg for food, then put the bait, they immediately rushed to grab the bait. When the water temperature at 15 degrees Celsius, more active foraging goldfish, water temperature exceeds 30 degrees, the goldfish will stop feeding, the water temperature below 5 degrees, significantly reduced foraging goldfish, water temperature of 18-25 degrees, The most vigorous appetite of goldfish, the fish is also the most rapid growth and development.

4, the stocking density
(1) commercial fish stocking densities: the growth rate of goldfish, the perfect shape, with the exception of water quality, food related, but also with the unit area on breeding mantissa. Lower stocking densities, the more well-developed goldfish, the most perfect shape of the curve. The higher stocking densities, the smaller the individual goldfish, thin body, malnutrition, decreased appearance of beauty, aesthetic value decreased.

5, four feeding points
(1) Spring: Spring temperatures moderate, is a goldfish and koi breeding season. Goldfish breeding work has focused on broodstock spawning and larval care. When the water temperature at 18-22 degrees Celsius, there will be chasing each other broodstock breeding activities. In the afternoon or evening when the new water into the broodstock for the next day, there is the dawn spawning activities. Labor before the goldfish should be kept in green water in order to control the color stability of the water quality of the sexual activities of broodstock. After spawning the broodstock should be kept in the pale green water, or in water mixed with some green water, with the green water to maintain normal development of gonad spawned, can be generally 7-10 days after the second spawning. Breeding parent fish should be fed during the live bait. In the southern region, there is a before and after the annual rainy season in June, when the rainy, all kinds of harmful bacteria, parasites multiply, which is the incidence of goldfish season, broodstock or juveniles should be taken regardless of feeding green water to reduce the times changing the water, maintain water quality and stability, to minimize stimulation, feeding should be reduced, especially low pressure hot day, feeding the amount of special attention. In case of goldfish disease should be promptly isolated, and drugs early prevention.
(3) Fall: fall water temperature suitable for the spring production of young fish into the fish have reached the stage, then feeding should focus on strengthening and maintaining the fish body fat, so fattening breeding work is focus on the fall. When the water temperature at 18-22 degrees, the water of harmful bacteria is strong when the observation and drug prevention should be strengthened to avoid a large number of ornamental fish disease and death. As rare as the Meiyu season of autumn, hundreds of days of rainy weather, to a lesser extent the incidence of ornamental fish, but because of suitable water temperature, but the fall season more ornamental fish disease, as long as the active prevention, generally can be weathered.
6, daily observation
(1) Observe the contents: the daily observation of fish is very important, it can detect early on_set_ of ill individuals or schools of fish, the observation of the main parts of the body surface, gills, eyes, mouth, fins, etc., these are Easy location of fish disease. Normal goldfish, bright and smooth surface, ups and downs with ease, appetite, abdominal body upright, tail stretch. Sick individuals, outlier travel alone, looked sluggish, feeding do not eat, dark body color, body surface mucus increased, there will be carefully watched the white surface mycelium or cotton wool or skin irritation such as congestive. Incidence of fish pond, fish tank corner or conflicting gathered together, this is a precursor to disease.
Normal goldfish, bright red gills, gill cover to open freely. Sick individuals, gill dim white, cottony mycelium, or decay or adhesion, operculum open weak, dull side of the pool, or corner. Goldfish developed a healthy stretch of the fins, rolling freely, sick goldfish fins lay on, unable to stretch, white spots on fins or congestive decay. If the fins are capsules bubbles are hot tail, as long as the replacement of the water will disappear. A sarcoma of the goldfish, sarcoma bright full, sick individual, sarcoma atrophy, lost its luster, or signs of decay.
Normal goldfish, eyes bright, gleaming, eyes turn freely and bright. Sick goldfish, eyes glazed, together with a layer of white film or flocculent mycelium. Healthy goldfish, mouth joint flexibility, looking for bait freely, the sick individual, mouth, joint failure, and swelling or rot.
Normal goldfish, appetite, often foraging in the bottom of the pool or poolside. Sick individuals, dull corner, feeding do not eat. Normal goldfish, feces into the article, the color gray. Sick individual, not a bar stool, milky white or bubbles. Feeding goldfish water color, water or green water is more appropriate for the growth of fish, whitish or brown color, must be promptly replaced.
7, so keeping the table in December
January: cold weather this month is the coldest season of the year, the work should be prepared to warm goldfish, goldfish can be moved to any condition or greenhouses overwintering indoors to minimize the water quality change, the work focused on the noon feeding .
February: In late February, the temperature is getting warmer and strengthen the work of feeding the goldfish. Water quality generally replaced every 30 or so. _Select_ion of broodstock, reducing stocking density, strengthening the parent fish fattening, as well the propagation of broodstock preparation.
March: Southern China in March, the average temperature of 10 degrees or so, sometimes the temperature will be higher than 20 degrees. As spring temperatures begin to rise, fed corruption, has significantly accelerated organic compounds in water in case of a few days to make southeast wind blowing, the temperature was rising, to the timely replacement of old water ornamental fish in winter to prevent anoxic goldfish. The latter part of March, ornamental fish gonad is mature, if the time at room temperature to increase temperature, goldfish will advance the breed. In fine weather, the different varieties of goldfish kept separate by a certain percentage in a fish pond, the well produced nest preparation.
April: before and after the Ching Ming Festival, ornamental fish into the breeding season, the focus should be transferred to brood care and the eggs hatch. Goldfish spawning in fresh water stability of more than desire to wait until estrus behavior, and back into the new water to lay eggs. Broodstock should be observed daily activities of the morning, in time the fish into the nest. At the same time make the eggs hatch and larval care.
May: It is the breeding of ornamental fish Jiangnan Wang period. Reasonable arrangements for broodstock Broodstock make the second, third spawning work, not spawning broodstock, feed and water to enhance nursed back to health. Forked caudal fin for juveniles, to change the water in time and the _select_ion is generally about 7 days changing the water once. May is the goldfish gill rot disease season, broodstock should be kept in green water, the reduction of water exchange times, so that broodstock to maintain a healthy state to a Meiyu season
June: Most of the Jiangnan region into the Meiyu season, the annual incidence is seasonal fish. In case of rainy weather, to regularly conduct regular conditioning liquid spill and water quality, particularly in the days when the weather is hot, but also to observe a timely manner, the timely processing of water quality, prevent the goldfish for a long period of mild hypoxia, lead to physical discomfort, to induce the production of disease. June has entered the color changing juvenile stage, pay attention to nutrition, make juvenile screening.
July: has entered the hot season, the monthly average temperature at 25 degrees, this time the focus is to prevent heat stroke and hot tail goldfish and enhance water exchange. July 35 degrees sometimes hot weather, pay attention to shaded pond. More concentrated feeding goldfish 7-8 in the morning when the water of goldfish changing the water about 4-5 days time. Most juvenile goldfish has entered the post-screening, should adjust stocking density to enhance juvenile fish fattening.
August: a year in the month of highest average temperature, outdoor fish pond to deepen the water level, the focus is to strengthen the sunstroke, to observe the phenomenon of goldfish and midnight hot end of the floating head, if necessary, all the water to be 2-3 days replaced. Feeding goldfish to keep the amount of saturation in the 7-8, to avoid the water with bait left, bait-corruption cause deterioration of water quality. Strengthen the small hours of observation, to prevent the entire pond goldfish bored from lack of oxygen cylinder deaths occurred.
September: September is still in early high temperatures, decreased temperatures in late September, goldfish feeding fattening focus is to strengthen and increase the amount of feeding. Usually 7-10 days changing the water once, strengthening the ornamental fish disease prevention and control of feed water from the water into the green water, stable body condition goldfish, goldfish fatten strengthen
October: cooler weather gradually, changing the water about 15 days time, changing the water temperature should be kept in balance of old and new goldfish. Outdoor fish pond could be considered appropriate to reduce the water level. October is the second year of ornamental fish disease, season, should pay attention to drug prevention, strengthen the work of goldfish fatten for winter lay the foundation for goldfish
November: getting cold temperature, water temperature more than 10 degrees, normal appetite, goldfish, about 20 days changing the water once, changing the water temperature when the note balance of old and new, ornamental fish kept in green water as far as possible, strengthen the sick individual's drug therapy
December: the temperature dropped, the focus this month is cold and warm goldfish. Decreased appetite, goldfish, about 30 days, changing the water once the work delayed until noon feeding, fish pond stocking density may be increased, the main color of green, open pond water level should be appropriate to deepen. |
