It is when some of the eggs are being fertised, a female shrimps will then carry eggs. I believe that ¦º§Z are dropped on the way to hatching and those fertised eggs continue to be developed to babies, as I have seen dropped eggs in my tank.

沒有公蝦雌蝦便有機會產死卵

如果冇公蝦攪母蝦, 母蝦係唔會產卵既,
而且母蝦同公蝦交配完, 母蝦會將精子儲存係體內, 授左精既卵先再排出, 掛係腹足個度.
所以有時缸只得母蝦, 母蝦都有剩餘精子係體內, 都有會抱卵,
所以基本上蝦係冇死卵既. 唔同好多魚咁, 母魚先產卵, 公魚先係卵上排精, 如果位置唔岩, 就有機會授唔到精既卵, 即係死卵吧.

Thanks!

Because when I chose 櫻花蝦, I found that some eggs in the shrimps are in bright yellow colour but some eggs are in dark yellow-orange color. So I am afriad I chose some shrimps with "死卵".

So......., does the colour of eggs indicate the time of shrimp holding eggs? And both bright and dark eggs are "live egg"?

並不一定的
當蝦群中沒有雄蝦,母蝦有機會產未授精的卵
沒錯,蝦是體內授精的.
