怎么判断金鱼是否怀孕

当金鱼准备产卵,就表示它怀孕了。金鱼是否怀孕是有迹可寻的。首先,判断金鱼是否具备怀孕的条件。其次,判断雌鱼和雄鱼是否都有“产卵前期”行为。只有雌鱼和雄鱼同缸,雌鱼才有可能怀孕。不排除你买回来的金鱼本来就有身孕,不过这个概率很低。

查看金鱼是否具备怀孕的条件

  1. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/a\/a6\/Tell-if-a-Goldfish-Is-Pregnant-Step-1-Version-2.jpg\/v4-460px-Tell-if-a-Goldfish-Is-Pregnant-Step-1-Version-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/a\/a6\/Tell-if-a-Goldfish-Is-Pregnant-Step-1-Version-2.jpg\/v4-728px-Tell-if-a-Goldfish-Is-Pregnant-Step-1-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 1 查看金鱼是否是雌鱼。要想知道金鱼的性别,最好的办法就是买金鱼的时候问问老板,或者请教兽医。通常来说,雌鱼的体态更丰腴。仔细一看,你还会发现雌鱼腹部更丰满,而雄鱼腹部更纤细。雌鱼位于腮后的胸鳍比雄鱼的更短,形状更圆。[1]
    • 此外,金鱼至少要长到一岁才会产卵。

查看金鱼是否有“产卵前期”行为

  1. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/e\/e5\/Tell-if-a-Goldfish-Is-Pregnant-Step-4-Version-2.jpg\/v4-460px-Tell-if-a-Goldfish-Is-Pregnant-Step-4-Version-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/e\/e5\/Tell-if-a-Goldfish-Is-Pregnant-Step-4-Version-2.jpg\/v4-728px-Tell-if-a-Goldfish-Is-Pregnant-Step-4-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 1 查看雄鱼身上是否有产卵结节。当雄鱼具备使雌鱼受孕的能力时,它的头、鳃盖和胸鳍周围会长出一些极小的白色凸点,被称为“产卵结节”。要是雄鱼有产卵疣粒,那么同缸的雌鱼怀孕的可能性就更大了。[4]
    • 产卵结节通常很难被发现。要是没发现,也不代表鱼没怀孕。
  2. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/a\/ac\/Tell-if-a-Goldfish-Is-Pregnant-Step-5-Version-2.jpg\/v4-460px-Tell-if-a-Goldfish-Is-Pregnant-Step-5-Version-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/a\/ac\/Tell-if-a-Goldfish-Is-Pregnant-Step-5-Version-2.jpg\/v4-728px-Tell-if-a-Goldfish-Is-Pregnant-Step-5-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 2 留意雄鱼是否追逐雌鱼。当金鱼准备产卵时,雄鱼经常追逐雌鱼,像共舞一样,被称为“求偶追逐”。通常,求偶追逐比产卵结节更容易被观察到。[5]
  3. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/5\/51\/Tell-if-a-Goldfish-Is-Pregnant-Step-6-Version-2.jpg\/v4-460px-Tell-if-a-Goldfish-Is-Pregnant-Step-6-Version-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/5\/51\/Tell-if-a-Goldfish-Is-Pregnant-Step-6-Version-2.jpg\/v4-728px-Tell-if-a-Goldfish-Is-Pregnant-Step-6-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 3 留意金鱼是否活跃。金鱼怀孕时通常会变得行动迟缓。倘若鱼游得慢或貌似行动困难,有可能怀孕了。[6]
    • 倘若金鱼出现“筑巢”行为,或者总躲在遮蔽物和植物旁,有可能是怀孕了。
  4. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/e\/ec\/Tell-if-a-Goldfish-Is-Pregnant-Step-7-Version-2.jpg\/v4-460px-Tell-if-a-Goldfish-Is-Pregnant-Step-7-Version-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/e\/ec\/Tell-if-a-Goldfish-Is-Pregnant-Step-7-Version-2.jpg\/v4-728px-Tell-if-a-Goldfish-Is-Pregnant-Step-7-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 4 留意金鱼是否厌食。金鱼准备产卵时可能会厌食。要是金鱼吃得比平常少,有可能不久就要产卵了。[7]
  5. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/8\/8f\/Tell-if-a-Goldfish-Is-Pregnant-Step-8-Version-3.jpg\/v4-460px-Tell-if-a-Goldfish-Is-Pregnant-Step-8-Version-3.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/8\/8f\/Tell-if-a-Goldfish-Is-Pregnant-Step-8-Version-3.jpg\/v4-728px-Tell-if-a-Goldfish-Is-Pregnant-Step-8-Version-3.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 5 留意金鱼的体型。雌鱼的身体通常比雄鱼圆润一些。金鱼准备产卵时,它的腹部会圆鼓鼓地突出来,比平常大很多。[8]
    • 与产卵结节同样的道理,肚子变大这种变化在某些品种的金鱼身上会很明显,而在一些品种的金鱼身上根本看不出来。
