不同阶段喂养金鱼的注意事项

金鱼（细节）

金鱼生活在水族馆中，水质的好坏将直接受到金鱼生长发育的影响。水不仅含有物理成分，还含有化学成分和生物成分。金鱼不同生长阶段应注意哪些饲养问题？编辑整理了一些供你参考。1、 金鱼在生长阶段的摄食1。金鱼幼虫期刚从卵膜孵化出来的鱼的器官发育不好，只能依靠吸收其卵黄囊中的营养来维持生命。卵黄囊中的营养在大约三天内被吸收，每个鳍的发育相对健全，消化器官已经形成，并开始从周围环境中摄取食物。2.从金鱼的嘴到性腺成熟的时间约为一年。幼鱼的存活率取决于是否有食物可吃。幼鱼以小而易消化的浮游动物为食，如轮虫和草履虫。注意：如果水中缺少这种饵料，可以用高度悬浮的微型鲤鱼饵或熟蛋黄粉代替。3.金鱼成体阶段的食物种类很多。常见的有较大的浮游动物和各种植物的残骸，以及水蚯蚓、麸皮、豆饼、大麦、荞麦和人工混合饲料，也吃池壁上的苔藓。金鱼（详细介绍）

2。不同生长阶段的金鱼繁殖1。金鱼养殖技术比较高，很多爱好者经常因为养殖失败而失去信心。即使是经验丰富的饲养员，有时也会因操作失误、粗心大意或恶劣天气的影响而蒙受损失。2.饲养规则是可以遵循的，但在金鱼养殖中也要遵循一些规则。只要你掌握了喂养的基本要领，虚心请教经验丰富的主人，并注意书本知识的学习，你就会逐渐得心应手。让我们首先了解大多数人关心的库存密度。3.金鱼的适宜密度是每单位面积金鱼的数量。掌握适当的密度对金鱼的正常生长、提高生长速度和形成良好的体型非常重要。适当的密度有利于形成短而胖的身体和发达的尾鳍。4.季节性气候影响（1）夏季和秋季：在炎热的夏季和秋季，水中溶解氧很少，金鱼消耗大量氧气，密度应较薄。（2） 春季雨季：通过降低密度或采取措施增加氧气来确保金鱼的安全更为重要。（3） 冬季：由于金鱼耗氧量少，放养量可以翻倍。5、耐氧性不强的娇嫩珍珠鳞片和水泡眼，产后的种鱼、老鱼和病鱼由于耐氧性差或体质差，不宜保持太近。6.幼鱼应以稀疏的密度和优良的体型和颜色放置。对于重点幼鱼，应增加密度，增加活饵的投喂量，有利于其快速生长。金鱼可以在浅绿色的水中饲养，短时间禁食，然后控制饲养，使其挨饿，限制其生长，并增加放养密度。7、金鱼密度控制的原则金鱼不缺氧，不漂浮。饲养者应在饲养过程中加强观察、及时控制和积累经验，妥善处理充分利用水面、节约管理和金鱼健康快速生长之间的矛盾。首先，它可以改善水质（通过吸收吸收水中的营养物质，通过光合作用释放氧气）。第二，它可以增加观看效果。9.水族馆中的藻类水族馆中的海藻通常是在种草或换水时带入的，但数量很少。此外，水族馆一般放置在室内，光线较弱。因此，藻类繁殖缓慢（尤其是在冬季）10。当水族箱在一定时间内完全换水时，需要加水或完全换水，而过于频繁的换水也对金鱼不利，因为每次都要适应新的环境。那么，我们应该如何延缓水质恶化，避免频繁换水？11.过滤和充氧过滤充氧的水植物和藻类可以吸收水中的营养物质并产生O2，但在夜间，由于没有光进行光合作用，因此不产生O2，并且每次都进行呼吸，这需要消耗O2，水族馆中的鱼密度也很大。因此，有必要配备充氧设备，一般使用筛选程序，不仅可以增加氧气，还可以过滤水质，增加观赏效果。12.注意饵料的新鲜度。首先，注意饵料的新鲜度。它不能发霉或腐烂。否则，很容易引起金鱼肠炎。如果不及时抢救，它就会死亡。诱饵不要太细。太细的饵料容易溶于水，导致金鱼在进食前溶解在水中，容易破坏水质。3、 饲养金鱼的注意事项1。应选择根系发达的水草。水草叶大，根系发达，吸收养分能力强，果实净化水质较好，叶大，抗恶劣环境能力强。水grasPrecautions for feeding goldfish at different stages

Goldfish (details)

Goldfish live in aquariums, and the quality of water quality will be directly affected by the growth and development of goldfish. Water contains not only physics, but also chemical composition and biology. What feeding problems should be paid attention to at different growth stages of goldfish? The editor has compiled some for your reference. 1、 The feeding of goldfish at the growth stage 1. The organs of the fish just hatched from the egg membrane at the larval stage of goldfish are not well developed, and can only rely on absorbing the nutrition in its yolk sac to maintain life. The nutrition in the yolk sac is absorbed in about three days, the development of each fin is relatively sound, the digestive organs have formed, and begin to take food from the surrounding environment. 2. The period from the goldfish's mouth to the maturity of the gonads is about one year. The survival rate of young fish depends on whether there is food to eat. Young fish feed on small, digestible zooplankton such as rotifers and paramecium. Note: If this kind of bait is lacking in the water, it can be replaced by the highly suspended, miniature carp bait or cooked egg yolk powder. 3. There are many kinds of food in the goldfish adult stage. The common ones are larger zooplankton and the debris of various plants, as well as water earthworms, bran, bean cake, barley, buckwheat and artificial mixed feed, and also eat moss on the pool wall.

2. Goldfish breeding at different growth stages 1. Goldfish breeding technology is relatively high, and many enthusiasts often lose confidence because of breeding failure. Even experienced breeders may suffer losses due to sometimes operating errors, carelessness or the impact of bad weather. 2. The feeding rules can be followed, but there are rules to follow in goldfish breeding. As long as you master the basic essentials of feeding, ask an experienced master with an open mind, and pay attention to the study of book knowledge, you will gradually become handy. Let's first understand the stocking density that most people care about. 3. The appropriate density of goldfish is the number of goldfish per unit area. It is very important to master the proper density for the normal growth of goldfish, improve the growth speed and form a good body shape. Proper density is beneficial to the formation of short and fat body and developed tail fins. 4. Seasonal climate impact (1) Summer and autumn: in hot summer and autumn, there is little dissolved oxygen in the water, and goldfish consume large amounts of oxygen, and the density should be thin. (2) Spring rainy season: It is more important to ensure the safety of goldfish by reducing the density or taking measures to increase oxygen. (3) Winter season: Because the oxygen consumption of goldfish is small, the stocking amount can be doubled. 5. The delicate pearl scales and blister eyes that are not strong in oxygen tolerance, and the post-natal breeding fish, aged fish and sick fish should not be kept too close due to poor oxygen tolerance or poor physique. 6. Juvenile fish should be placed with sparse density and excellent body shape and color. For the key young fish, the density should be increased to increase the feeding of live bait, which is conducive to its rapid growth. The goldfish can be raised in light green water, fasting for a short time, and then controlling the feeding to make them starve, limit their growth, and increase the stocking density. 7. The principle of density control of goldfish density is that goldfish do not lack oxygen and do not float. The breeder should strengthen observation, timely control and accumulate experience during the breeding process to properly handle the contradiction between making full use of water surface, saving management and healthy and rapid growth of goldfish, First, it can improve water quality (absorb nutrients in water through absorption and release oxygen through photosynthesis). Second, it can increase the viewing effect. 9. Algae in the aquarium The algae in the aquarium are usually brought in when planting grass or changing water, but the quantity is small. In addition, the aquarium is generally placed indoors, and the light is weak. Therefore, the algae reproduce slowly (especially in winter) 10. When the aquarium completely changes water for a certain time, it is necessary to add water or completely change water, and too frequent water change is also unfavorable for goldfish, because each time it has to adapt to a new environment. So, how should we delay the deterioration of water quality and avoid changing water too frequently? 11. Filtration and oxygenation Filtration Oxygenated water plants and algae can absorb nutrients in water and produce O2, but at night, because there is no light for photosynthesis, no O2 is produced, and respiration is carried out every time, which requires O2 consumption, and the density of fish in the aquarium is also large. Therefore, it is necessary to equip with oxygenation equipment, generally using screening procedures, which can not only increase oxygen, but also filter water quality, and increase the viewing effect. 12. Pay attention to the freshness of the bait. First of all, pay attention to the freshness of the bait. It must not become moldy or rotten. Otherwise, it is very easy to cause goldfish enteritis. If it is not rescued in time, it will die. The bait should not be too fine. Too fine bait is easy to dissolve in water, causing goldfish to dissolve in water before eating, which is easy to damage the water quality. 3、 Precautions for raising goldfish 1. The water grass with developed root system should be selected. The water grass with large leaves, developed root system, strong ability to absorb nutrients, better fruit for purifying water quality, larger leaves, strong ability to resist adverse environment. The water grass with small leaves is easy to fall off and rot when the water is turbid. 2. Don't put garbage fish. The scavenger fish can scrape the food residue at the bottom and wall of the tank, but it is also good at eating grass, which is not conducive to the growth of water plants. 3. A few small loaches can be put in. Some of the dung or food residue of goldfish will fall into the glass frame of grass planting, while the loaches like to drill around, and they will lift these things up and suck them out during the drilling process, and the loaches will also eat the food residue, which plays a role in assisting in purifying water quality
