Male or Female that is the question ?

[LeeB]

This question is from Casey

How do you sex koi ? your thoughts please

[Tinca Tinca]

Could you tell by the pectoral fins ? Like if they are rounded its a female and if they are more pointy its a male ?

[jamesc777]

By the name i give them

Females are plumper (been polite) than the males and males have rough gill plates i think like stubble. Thats as much as i think i know, also these cant generally be spotted untill they are sexually mature.

How have i done?

[Ralph]

I usually try and cope a feel before i tickle her tonsils

As above only thing i have really heard is about the fins

I married a fat cow does that also count :p

Shes a Koi Widow she wont come on here

[brian1962]

always a difficult thing i think, but i tend to go on body shape and fin shape and colour, female fins tend to be more round and opaque and the males pointier and more colour this gets easier as they mature as the females fill with eggs they get the blimp shape whereas the males are more streamlined.
I also watch them in the spring/summer as the water warms up for signs of spawning.

Put a picture of a calendar koi at one ond of the pond and those that goto it are male and the ones saying how fat she is are female?

[johnsb00]

i think its disgraceful that you all choose to mock a serious question
we all know that the females carry fin bags

[Casey]

Ok folks, serious answers from this point onwards thank you.
