教你如何分辨金鱼的雌雄

普通人喜欢成对饲养金鱼，因为偶数是吉祥的，成对也有幸福的含义。另一方面，一些饲养者尝试进行一些养殖，以进一步探索金鱼生长发育的知识以及在养殖过程中鱼类养殖的乐趣。要能够准确识别金鱼的雌雄，除了掌握书中介绍的基本要点外，更重要的是仔细观察不同金鱼品种在长期饲养过程中的外部形态和游动的差异以及不同时期金鱼外部形态的变化。雄性和雌性金鱼主要从以下几个方面进行区分：1。外形差异：1。体型的差异：雄性金鱼一般稍长，而雌性金鱼则短而圆。产卵期雌鱼的腹部比雄鱼的腹部大。2.尾柄的区别：雄鱼比雌鱼略粗。3.胸鳍的差异：仔细观察发现，雄鱼略尖且长，胸鳍第一鳍较粗且坚硬；雌鱼短而圆，胸鳍的第一鳍并不太硬。4.射精孔的区别：从腹部向上看，雄鱼的射精孔小、窄、凹；雌鱼的排气孔大而略圆，向外突出。2、 颜色差异：不同性别的金鱼的体色略有不同。雄鱼一般颜色鲜艳，而雌鱼颜色稍浅。在生殖发育期，雄鱼的体色更鲜艳。3、 触摸和移动：用手轻轻握住鱼的腹部。中指和无名指感觉男性腹部有明显的硬纹，而女性腹部柔软。当走在鱼塘边时，雄鱼游得又快又敏捷，而雌鱼游得很慢。4、 寻星：随着温度的升高，金鱼在产卵期会出现第二个特征——寻星，这是识别金鱼性别最简单、最准确的时间，也是最容易掌握的方法。雄鱼的寻星出现在胸鳍的第一根刺和鳃盖的边缘。大多数时候，整个胸鳍的每个鳍上都有追星。前部很明显，只有仔细观察才能观察到后部。这个粗糙的小白点在追逐星星。使用上述鉴定方法，我们必须依靠多年的饲养经验和平时的仔细观察，才能准确识别金鱼的雌雄

Teach you how to distinguish the male and female of goldfish

Common people like to breed goldfish in pairs, because even numbers are auspicious, and pairs also have the meaning of happiness. On the other hand, some breeders try to do some breeding in order to further explore the knowledge of goldfish growth and development and the fun of fish breeding during the breeding process. To be able to accurately identify the male and female of goldfish, in addition to mastering the basic points introduced in the book, the more important thing is to carefully observe the differences in the external morphology and swimming of different goldfish species and the changes in the external morphology of goldfish in different periods during the long-term feeding process. The male and female goldfish are mainly distinguished from the following aspects: 1. The difference in external shape: 1. The difference in body shape: the male goldfish is generally slightly longer, while the female goldfish is short and round. The abdomen of female fish is larger than that of male fish during spawning period. 2. Difference of tail handle: male fish is slightly thicker than female fish. 3. Difference of pectoral fin: careful observation shows that the male fish is slightly pointed and long, and the first fin of pectoral fin is thicker and hard; The female fish is short and round, and the first fin of the pectoral fin is not too hard. 4. The difference of the ejaculatory hole: from the belly up, the male fish's ejaculatory hole is small, narrow, and concave; The female fish's vent hole is large and slightly round, protruding outward. 2、 Color difference: goldfish of different sexes differ slightly in body color. The male fish is generally bright in color, while the female fish is slightly lighter. During the reproductive development period, the male fish is more bright in body color. 3、 Touch and movement: gently hold the fish's abdomen with your hand. The middle finger and ring finger feel that there is an obvious hard line on the male's abdomen, while the female's abdomen is soft. When walking by the edge of the fishpond, the male fish swam fast and agile, while the female fish moved slowly. 4、 Star-seeking: With the increase of temperature, goldfish will appear the second characteristic during spawning period - star-seeking, which is the easiest and most accurate time to identify the sex of goldfish, and also the easiest way to master. The male fish's star-seeking appears on the first thorn of the pectoral fin and the edge of the gill cap. Most of the time, the whole pectoral fin has star-seeking on each fin. The front part is obvious, and the rear part can be observed only after careful observation. This rough little white spot is chasing stars. Using the above identification methods, we must rely on years of experience in breeding and careful observation at ordinary times to accurately identify the male and female of goldfish
