Hello friends:
>
> Iīm Carlos Rodriguez from Spain. I am currently taking underwater photos
> and video from spawing pikes at rivers in my country. in fact Iīm writing
> a paper about this for some angling journals but I have a very big
> problem: after a huge time spent diving with them I have observed that some
> individuals figth, but I am in doubt if they are male or female (in our
> rivers, except some very big females, it could be difficult to
> differenciate them only by means of size....)
> As different males follow the female, I think there is no reason for the
> males to figth. So they have to be the females...but why?
>
> I couldnīt find any scientific publication about the real spawning
> behaviour of pike; if any of you can help me I will very much appreciate
> it.

> Thank you very much for your kindness
