孔雀鱼繁殖的问题
孔雀鱼繁殖的问 孔雀鱼繁殖的问题: 1.鱼妈妈就快要下鱼宝宝了~怎么办,我还有一个小鱼缸, 可以给母鱼生小鱼用, 可是我可以把两条母鱼同时放在一个缸里吗,他们会不会互相吃他们的鱼宝宝呢,, 答: 可以放在一起,切记下完后要把母鱼捞出来,它会吃小鱼的。缸不要太小了,要不母鱼会很急不安.孔雀是卵胎生的,可以买个生小鱼箱好了。把箱直接放在一比箱大的缸里,母鱼爱什么时候生就什么时候生,不用担心会吃小鱼了。当然缸里不可以再有其它鱼了不然母鱼不吃其实鱼也会吃掉小鱼的。 2.鱼肚子大到什么程度才算有小鱼了呢, 答:只要不是撑大的就是有了~ 但是不一定是要生的~ 要生的时候腹部后面发黑几乎能看见里面的小鱼了,同时肛门又凸起的时候就是要生了~ 3.白子孔雀产前征兆是什么, 答: 白子母鱼一般跟野生色母鱼一样,产前产道微开,成直角,有很明显的生殖孔突出,看肚子大小不一定准. 4.小鱼生出来后喂什么, 答:小水蚤、小鱼粉、丰年虾、微虫、蛋黄水(熟的鸡蛋黄捻碎)、剪碎的红虫,饲料可以喂捻碎的鱼虫干或者是干饲料都可以(捻成粉末状),喂活食小鱼会长得比较快. 5.我的小鱼快两个月了,才4,5厘米,而且现在长的速度越来越慢了,小鱼生长速度最快的时段应该是什么时间,到多大的时候就不会生长了呢, 答:小鱼出生后两个月是长身体的时候,然后就开始比较缓慢地长大,这时候就开始接近成鱼,尾巴和背鳍变大变长,花色更艳丽.小鱼从出生后半年基本稳定下来. 6.如何预防母鱼难产?母鱼肚子已有一定规模,但还没有生的迹象,已经换缸,一日数餐,红虫,饲料,血虫, 胃口好,不好动。 答:别惊吓它,好水好饲料,准备生的时候换新水刺激一下,再生不出就没啦. 肚子大不爱运动很正常.孔雀不会撑死的,不过喂食过多沉在缸里很容易坏水. 7.请问为什么我的孔雀生下来的小鱼有一半还是卵?不说是胎生吗, 答:没完全受精或者已经受精但是没有发育好,也可能是血统太近或者营养不良。避免突然的变化(温度和水质量突然变化还有人为惊吓),好饲料伺候. 8.怎么分公母?(资料来自台湾老爹孔雀鱼交流网) 答:孔雀鱼公鱼正确的分辨方式是由腹鳍後的交尾器来判别,其他如尾鳍大小、颜色鲜豔等特徵可作为辅助判别,但有可能造成误判;母鱼则是由胎斑来判别,胎班即是位於腹鳍之上左右位置的黑色斑点,随著母鱼的长大与成熟,授精後的胎斑会越来越大,代卵正逐渐发育成熟,一般来说,原生色母鱼的胎斑是黑色的,而黄化种及白子的胎斑呈现黄红色,但若子代为原生色,则胎斑也会随之变成黑色。 仔鱼需等到胎斑出现才能分公母,约时一个月左右,如果说需要处女母鱼,只要当母鱼胎斑出现後(母鱼一定比较早出现胎斑),将母鱼捞出。剩下的即是公鱼,如此是比较保险的做法。 9.生产前兆?(资料来自台湾老爹孔雀鱼交流网) 一般来说,受精过的母鱼可以在28天内生下幼鱼,但在夏天会缩短怀孕其至三个星期左右,母鱼要生的时候一些特别的样子,可以利用这些产前特徵将待产的母鱼放置产子箱中: 【1】母鱼的肚子胀得大大的,在胎斑处成方型。 【2】开始拉黑便,排便较为粗大。 【3】不太爱进食。 【4】总是静静的在一旁,并驱逐其它鱼只*近。 【5】很明显的可以发现缸门口有点突突的。 【6】臀鳍会缩起,并不时会扬起尾部。 real, in each pen business lending Qian not for by pen query, led to mortgage failure of.
