三个方面教你区分雄性和雌性金鱼
金鱼（细节）如果你想在家里养殖金鱼，你必须区分金鱼的性别。以下是如何从三个方面区分雄性和雌性金鱼。雄性和雌性金鱼主要从以下几个方面进行区分：一、外部形态的差异（1）体型的差异：雄性金鱼的体型一般稍长，而雌性金鱼的体型则较短而圆。产卵期雌鱼的腹部比雄鱼的腹部大。（2） 尾柄的区别：雄鱼比雌鱼稍厚。（3） 胸鳍的区别：仔细观察发现，雄鱼略尖且长，胸鳍的第一鳍较粗且坚硬；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、 雄性和雌性金鱼的颜色差异在体色上略有不同。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、 手感和动作：用手轻轻握住鱼的腹部。中指和无名指感觉雄鱼腹部有明显的硬纹，而雌鱼腹部柔软。当走在鱼塘边时，雄鱼游得又快又敏捷，而雌鱼游得很慢。跟随星星。随着温度的升高，金鱼在产卵期会出现第二个特征——追星，这是识别金鱼性别最容易、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
Three aspects teach you to distinguish between male and female goldfish
goldfish (details) If you want to breed goldfish in your home, you must distinguish the sex of goldfish. The following is how to distinguish between male and female goldfish from three aspects. Male and female goldfish are mainly distinguished from the following aspects: First, differences in external morphology (1) differences in body shape: male goldfish generally have a slightly longer body shape, while female goldfish have a shorter and round body. 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、 The difference of color between male and female goldfish is slightly different 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、 Hand feeling and movement: hold the abdomen of the fish gently with your hand. The middle finger and ring finger feel that there is an obvious hard line on the abdomen of the male fish, while the female fish has a soft abdomen. When walking by the edge of the fishpond, the male fish swam fast and agile, while the female fish moved slowly. Follow the stars. With the increase of temperature, goldfish will appear the second characteristic during spawning period - chasing stars, 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
