金鱼的饲养方法是什么

红珍珠

金鱼对我们来说并不陌生，可以说是一种非常常见的水族馆。家里有很多金鱼。许多孩子会觉得这很有趣，经常喂金鱼吃。这种方法是错误的。父母应该停止这种行为。过度喂养可能会导致金鱼死亡。喂金鱼的正确方法是什么？1、 金鱼的饲养1。在幼虫阶段，金鱼是产卵的动物。仔鱼从蛋里出来后，就不能吃东西了。腹部有一个大的卵黄囊。孵化后2-3天内，它依靠卵黄囊中的营养存活。当卵黄囊中的营养耗尽时，金鱼幼虫必须从外部环境中获取食物，这就开始了金鱼的生命摄食活动。与成年金鱼不同，幼虫需要吃相对较小的浮游生物，如轮虫、草履虫等，因为它们没有成熟的消化器官。较大的幼虫可以喂养红虫，如枝角虫、枝孢子虫等，也可以在人工喂养下被鸡蛋或鸭蛋的蛋黄碎片代替。幼虫期的饲养将直接影响金鱼鱼苗的质量。2.鱼苗期较大的金鱼可以喂食动物性食物，如水蚤、潜水蚤、蚯蚓（水虫）、蜗牛、虾肉或其他动物内脏碎片。植物食物包括浮游藻类（金藻、黄藻、绿藻、甲藻、硅藻和蓝藻），金鱼聚集在一起时可以食用。蔬菜食物，如菠菜、卷心菜、莴苣叶、胡萝卜丁、红薯丁等。一般来说，在金鱼饥饿时喂它们是有效的。蔬菜应无农药污染，以避免中毒。3.在半成年和成年的这个阶段，我们可以主要使用人工配方饲料，动物蛋白含量在40%以上（鱼粉、蚕蛹粉等），豆粕粉20%，玉米粉10%，麦麸30%和一些微量元素。在营养方面，基本可以满足5厘米以上金鱼的需求。黑龙眼

2。金鱼养殖注意事项1。水技巧1）首先清洁透明的鱼缸（其他器皿也可以，但一定要透明）2）使用苏打水。如果没有苏打水，用冷开水代替。但切记千万不要使用自来水，因为自来水中有消毒的氯，小金鱼不能吃。3）水应该尽可能多，以确保良好的氧气含量和鱼类的充分自由。最好买一个小型空气泵用于养鱼。2、饲养小贴士1）如果没有条件保持鱼缸的水温，在这个寒冷的冬日里，金鱼应该经常得到充足的阳光。2） 在鱼缸里放一些白米石和一些水草，但要记住水草必须适当。3） 在喂养方面，可以放一些鱼虫或者白面馒头，但每次都要少喂多喂。此外，需要注意的是，小金鱼特别容易患白斑病（一种寄生虫病）。如果你发现鱼身上有这种东西或鱼鳞脱落并有伤口，记得在花鸟市场买一种“黄色粉末”（主要是消炎药），然后在给鱼换水时滴一些甲基蓝药水（主要是抗寄生虫药）。在你的精心照料下，小金鱼会给你带来同样的快乐。3、 喂食方法是先准备好鱼容器，并提前擦干水。如果你想铺沙子和种草，你需要在一切准备就绪后慢慢加水。把水弄干大约需要一两天。然后将装有金鱼和“老水”的塑料袋放入水族馆，使其悬挂在水体的中上层。大约半小时后，估计塑料袋中的水温接近水族馆。同时，在水中加入1茶匙盐进行消毒。等待1-2天，然后在水族馆中喂食鱼。如果需要增加放养数量，应将新鱼放在另一个容器中保存7-10天，然后将鱼与原水族馆的鱼一起保存，以避免带来病原体。1、投喂方法金鱼投喂期使用的饵料一般包括人工饵料和天然饵料。喂食必须严格定时和定量，以保持水的新鲜。一般来说，诱饵的数量应为每天1-2次，早晚各一次，晚上一次应早不宜晚。此外，喂食的时间、频率和数量也应根据以下原则确定：（1）当天气晴朗、阳光温暖、风温暖、水中溶解氧充足、水温适宜时，可以适当多喂食。（2） 当水很薄，鱼的胃口很好时，你可以多放一些饵。（3） 如果鱼生病了，或者鱼的品种很娇贵，那么应该少喂粗粮，多喂一些细粮。为了确定金鱼的饥饿程度和饱和消化吸收程度，可以根据鱼粪的颜色来区分。如果鱼粪呈绿色、棕色或黑色，则表示鱼体适合进食，吸收良好。如果鱼粪是白色的，说明鱼吃得太多了。2.为了在室内饲养金鱼，我们首先要解决光照问题：因为金鱼的美不仅在于形状，还在于颜色。为了确保鱼的颜色明亮，我们必须确保鱼的身体接受强光，否则What are the feeding methods of goldfish

Goldfish is no stranger to us. It can be said that it is a very common aquarium. There are many goldfish in the family. Many children will find it funny and feed goldfish food constantly. This method is wrong. Parents should stop it. Excessive feeding is likely to cause goldfish death. What are the correct ways to feed goldfish? 1、 Feeding of goldfish 1. At the larval stage, goldfish are egg-laying animals. After the larval fish comes out of the egg, it cannot eat food. There is a large yolk sac in the abdomen. Within 2-3 days after hatching, it depends on the nutrition in the yolk sac to survive. When the nutrition in the yolk sac is exhausted, the goldfish larvae have to get food from the external environment, which starts the goldfish's life feeding activities. Unlike adult goldfish, larvae need to eat relatively small plankton, such as rotifers, paramecium, etc., because they do not have mature digestive organs. Larger larvae can feed red worms, such as cladocera, cladosporus, etc., and can also be replaced by egg yolk fragments of eggs or duck eggs under artificial feeding. Feeding at the larval stage will directly affect the quality of goldfish fry in the future. 2. The goldfish with larger fry stage can be fed with animal food such as water fleas, diving fleas, earthworms (water worms), snails, shrimp meat or other animal offal fragments. The plant food includes planktonic algae (golden algae, yellow algae, green algae, dinoflagellate, diatom and cyanobacteria), which can be eaten by goldfish when they gather into a group. Vegetable foods, such as spinach, cabbage, lettuce leaves, diced carrots, diced sweet potatoes, etc. Generally, it is effective to feed goldfish when they are hungry. Vegetables should be free from pesticide pollution to avoid poisoning. 3. At this stage of half-adulthood and adulthood, we can mainly use artificial formula feed, with animal protein content of more than 40% (fish meal, silkworm pupa powder, etc.), soybean meal powder of 20%, corn flour of 10%, wheat bran of 30% and some trace elements. In terms of nutrition, it can basically meet the needs of goldfish above 5cm. Black Dragon Eyes

2. Precautions for goldfish breeding 1. Water skills 1) First clean the transparent fish tank (other utensils are OK, but be sure to be transparent) 2) Use soda water. If there is no soda water, use cold boiled water instead. But remember never to use tap water, because there is disinfected chlorine in the tap water, and the little goldfish can't eat it. 3) Water should be as much as possible to ensure good oxygen content and full freedom of fish. It is best to buy a small air pump for fish farming. 2. Feeding tips 1) If there is no condition to maintain the water temperature of the fish tank, the goldfish should be given enough sunshine frequently in this cold winter day. 2) Put some white rice stones and some water plants in the fish tank, but remember that the water plants must be appropriate. 3) In terms of feeding, you can put some fish worms or steamed bread with white flour, but you should feed less and more frequently each time. In addition, it should be noted that small goldfish are particularly prone to white spot disease (a parasitic disease). If you find such things on the fish or the scales fall off and have wounds, remember to buy a kind of "yellow powder" (mainly anti-inflammatory) at the flower and bird market, and then drop some methyl blue liquid medicine (mainly antiparasitic) when changing the water for the fish. Under your careful care, the little goldfish will bring you equal happiness. 3、 The feeding method is to prepare the fish container first, and dry the water in advance. If you want to lay sand and plant grass, you need to add water slowly after everything is ready. It takes about one or two days to dry the water. Then put the plastic bag containing goldfish and "old water" into the aquarium and make it hang in the middle and upper layer of the water body. After about half an hour, it is estimated that the water temperature in the plastic bag is close to the aquarium. At the same time, add 1 teaspoon of salt in water to sterilize. Wait for 1-2 days before feeding the fish in the aquarium. If it is necessary to increase the stocking quantity, the new fish should be kept in another container for 7-10 days, and then the fish should be kept together with the fish in the original aquarium to avoid bringing pathogens. 1. Feeding method The bait used in goldfish feeding period generally includes artificial bait and natural bait. Feeding must be strictly timed and quantified to keep the water fresh. Generally speaking, the number of baits should be 1-2 times a day, one time in the morning and one time in the evening, and one time in the evening should be early rather than late. In addition, the time, frequency and quantity of feeding should also be determined according to the following principles: (1) When the weather is sunny, the sun is warm and the wind is warm, the dissolved oxygen in the water is sufficient, and the water temperature is appropriate, more feeding can be appropriate. (2) When the water is thin and the fish has a strong appetite, you can put more bait. (3) If the fish is diseased or the species is delicate and precious, it should be fed with less coarse food and some fine food instead. To identify how the goldfish's hunger and saturation digestion and absorption are, it can be distinguished according to the color of the fish dung. If the fish dung is green, brown or black, it means that the fish body is suitable for feeding and well absorbed. If the fish dung is white, it indicates that the fish is overfed. 2. In order to raise goldfish indoors, we should first solve the problem of lighting: because the beauty of goldfish is not only the shape, but also the color. To ensure the bright color, we must ensure that the fish body accepts strong light, otherwise, the color of the fish body will become increasingly dim. And it is easy to catch diseases, so the goldfish feeding place should have sufficient light source, and ultraviolet light source is better. If the temperature is appropriate, the aquarium can be placed on the balcony or in front of the window during the day to ensure the quality and sufficient illumination. Therefore, mastering the temperature suitable for goldfish growth and ensuring its sufficient light, indoor goldfish breeding has a great guarantee. In a word, goldfish must be raised in the right way. It is not allowed to feed goldfish blindly, change water regularly, and clean up the sundries in the bathtub, so as to ensure the health of goldfish
