简要介绍珍珠金鱼的繁殖规则

金鱼（详细信息）

金鱼是我们水族爱好者非常喜爱的鱼类。这在我们普通家庭饲养中很常见。金鱼色彩斑斓，很有吸引力。金鱼养殖很容易上手，其养殖条件相对宽松。很多新手可能第一次养金鱼，但如果你真的想养好金鱼，你需要努力。我们都知道金鱼有很强的生命力，可以在没有任何管理的情况下生存。然而，长期忽视管理会增加金鱼患病的概率。因此，为了避免金鱼出现一些不必要的症状，我们应该注意各方面的方法。1、 繁殖密度必须紧密结合。当幼鱼生长到一定程度，珠鳞开始显著生长时，密度应稍密，以控制鱼体的生长速度，使鱼体和珠鳞以及头部的冠部达到平衡生长。当珠鳞和头型生长时，密度必须再次变薄，以达到快速均衡生长的效果。大约一个月后，应再次增加密度，并进行精耕细作，以提高金鱼的抵抗力和珍珠鳞片的防脱落能力。2、 水质和水温条件金鱼适合用稳定的绿水或淡水养殖，但不适合用老绿水和淡水养殖。在老绿水养殖时容易出现水痘、肩膀松脱、珠鳞松脱等不良现象。因为金鱼是变温动物，虽然它们可以在0-30℃下生存，但最适合它们生长的温度是20-28℃。对于金鱼，不建议在冬天更换所有的水，通常只更换鱼缸底部的水和鱼粪便，并通过管道泵出。在夏季，洪水通常每周更换一次。每3-4天更换一次底层水。底部水交换体积通常为鱼缸中水的三分之一或一半。3、 珍珠金鱼的饲养方法珍珠金鱼的三大要点是：头型、体型和珍珠鳞片。体型的增长与珠鳞的增长有一定的矛盾关系。在养殖过程中，主要调整摄食：幼鱼主要考虑体型和体型的生长，因此必须以高能量、高蛋白的全价饲料为主。当其生长到一定程度时，珍珠鳞片的生长开始凸显，应注意饲养调整。此时，需要考虑珍珠鳞片生长所需的营养物质，主要是钙的补充，并合理控制鱼体的生长，否则，珠鳞的生长和鱼体的生长将不一致，从而导致松肩、松珠鳞等疾病，并可能导致珠不完整。过了这个阶段，进入成鱼繁殖期后，只要投喂均衡，繁殖就成功了一半。但有三点需要注意，第一，新鲜饵料和混合颗粒必须在不同时期合理搭配。稍有疏忽的结果要么不够圆润，要么珍珠鳞片不完整或松散，要么牙冠不发达。第二：最佳喂食量为8-9%饱腹。过多会导致鱼体过于肥胖、松弛、肩部松弛和珠鳞松弛。太少会导致鱼体太薄，不够圆。第三，少量的鱼要多次喂食，使鱼体和珍珠鳞片生长均匀。4、 我们可以在金鱼身上放浮标吗？首先，喂金鱼的浮萍不能大面积或完全覆盖鱼缸。喂入金鱼缸的浮萍不应超过金鱼缸水域面积的1/5，浮萍应放入食物地供鱼食用。如果浮萍漂浮并覆盖整个水面，会影响水体中藻类的光合作用，造成池水缺氧。对金鱼的伤害是致命的，所以浮萍只能放在适量，而不能放大量。其次，不要在闷热或雷雨天气放置大量浮萍。由于闷热天气的特殊原因，鱼缸中的溶解氧含量会下降。如果此时将浮萍放入鱼缸中，鱼缸中的溶解氧会进一步减少，严重时容易导致金鱼死亡。第三，不要在晚上或晚上喂食浮萍，因为晚上或晚上放入鱼塘的浮萍由于自身的呼吸作用，会消耗大量水中的溶解氧；此外，金鱼在夜间吃饱后也会增加呼吸耗氧量，这两者都会导致池水缺氧。在严重的情况下，金鱼也会死亡。5、 当没有人照顾金鱼时，金鱼应该怎么做？当我们在家里养金鱼时，常见的问题是主人必须外出，不能照顾金鱼。这个时候我们该怎么办？在我们离开之前，我们可以清洁一次水族馆，彻底清洁鹅卵石、水草、过滤器等，吸出污垢，并用1/4的新恒温水替换，停止喂食，检查过滤器、电源等是否有任何问题，然后放心地出门。关键是要害怕停电。如果没有停电，就不会发生重大事件。一般来说，鱼半个月不进食不会饿死，因为成鱼的饥饿感很强A brief talk on the breeding rules of pearl goldfish

Goldfish (details)

Goldfish is a very popular fish for our aquarium enthusiasts. It is very common in our ordinary family breeding. Goldfish are colorful and attractive. It is easy to get started with goldfish breeding, and its breeding conditions are relatively loose. Many novices may raise goldfish for the first time, But if you really want to raise goldfish well, you need to work hard. We all know that goldfish have strong vitality and can survive without any management. However, long-term neglect of management will increase the probability of disease for goldfish. Therefore, in order to avoid some unnecessary symptoms for goldfish, we should pay attention to methods in all aspects. 1、 The breeding density must be closely and thinly combined. When the young fish grow to a certain extent and the pearl scale begins to grow prominently, the density should be slightly denser to control the growth speed of the fish body, so that the fish body and the pearl scale and the crown of the head can achieve balanced growth. When the pearl scale and the head form grow, the density must be thinned again to achieve the effect of rapid and balanced growth. In about a month, the density should be increased again, and the intensive cultivation should be carried out, In order to improve the resistance of goldfish and the anti-dropping ability of pearl scales. 2、 Water quality and water temperature conditions Goldfish are suitable for breeding with stable green water or fresh water, but not with old green water and fresh water. It is easy to have chickenpox, loose shoulder, loose bead scales and other adverse phenomena when breeding in old green water. Because goldfish are temperature-changing animals, although they can survive at 0-30 ℃, the most suitable temperature for their growth is 20-28 ℃. For goldfish, it is not recommended to change all water in winter, Generally, only the water at the bottom of the fish tank and the fish feces are changed and pumped out through the pipe. In summer, the flood is usually changed once a week. Change the bottom water every 3-4 days. The bottom water exchange volume is generally one third or half of the water in the fish tank. 3、 Feeding methods Pearl goldfish Pearl goldfish's three main points are: head shape, body shape and pearl scale. The growth of body shape and the growth of pearl scale have a certain contradiction relationship. During the breeding process, feeding is mainly adjusted: the growth of body shape and body size is mainly considered for young fish, so it must be mainly fed with full-price feed with high energy and high protein. When it grows to a certain extent, the growth of pearl scale begins to highlight, attention should be paid to the feeding adjustment, At this time, it is necessary to consider the nutrients needed for the growth of the pearl scale, mainly the calcium supplement, and to reasonably control the growth of the fish body, otherwise the growth of the pearl scale and the growth of the fish body will not be consistent, resulting in loose shoulder, loose bead scale and other diseases, and may cause incomplete bead. After this stage, after entering the adult fish breeding period, as long as the feeding is balanced, the breeding will be half successful. However, there are three points that should be paid attention to. First, fresh bait and mixed pellet must be reasonably matched in different periods. The result of a little inattention is either not round enough, or the pearl scales are incomplete or loose, or the crown is not developed. Second: The best feeding amount is 8-9% full. Too much will lead to the fish body being too fat, loose, loose shoulder and loose bead scales. Too little will lead to the fish body being too thin and not round enough. Third, a small amount of fish should be fed for many times to make the fish body and pearl scales grow evenly. 4、 Can we put buoys on goldfish? First of all, the duckweed fed to goldfish can not cover the fish tank in a large area or completely. The duckweed fed to goldfish tank should not exceed 1/5 of the water area of the fish tank, and the duckweed should be put into the food ground for fish to eat. If the duckweed floats and covers the whole water surface, it will affect the photosynthesis of algae in the water body and cause anoxia in the pool water. The damage to goldfish is fatal, so duckweed can only be put in a moderate amount, not a large amount. Secondly, do not put a large number of duckweeds in the sultry or thunderstorm weather. Due to the special reason of muggy weather, the amount of dissolved oxygen in the fish tank will drop. If duckweed is put into the tank at this time, the dissolved oxygen in the fish tank will be further reduced, and in serious cases, it will easily lead to the death of goldfish. Third, duckweeds should not be fed in the evening or at night because duckweeds put into the fish pond in the evening or at night will consume a lot of dissolved oxygen in the water due to their own respiration; In addition, goldfish will also increase the respiratory oxygen consumption after they are full at night, both of which can cause anoxia in the pool water. In serious cases, goldfish will also die. 5、 What should goldfish do when there is no one to take care of it? When we raise goldfish at home, the common problem is that the owner has to go out and cannot take care of the goldfish. What should we do at this time? Before we leave, we can clean the aquarium once, thoroughly clean the pebbles, water plants, filters, etc., suck out the dirt, and replace it with 1/4 of the new isothermal water, stop feeding, check the filter, power supply, etc. for any problems, and then go out with confidence. The key is to be afraid of power failure. If there is no power failure, there will be no major event. Generally speaking, fish will not starve to death without feeding for half a month, because adult fish have strong hunger tolerance. On the contrary, some first-time fish keepers, before going out, fed the fish full. As a result, when they went out and came back, all the fish died, because after the fish were full, dry feeding required a large amount of water, which swelled the fish to death. This is the experience of the fish farmers who often say that "fish will never die if they are hungry, but they will die if they are too full". Of course, young fish should not be hungry for a long time, otherwise they will not grow big and fat
