Title: Salmon on the Redds
Post by: nessy on 28/01/2012 at 20:16

I'm always hearing Anglers being advised to take the cock salmon but return the hens! does anyone have any opinions on this subject ? I've always thought cocks and hens pair up so whats the point in the redds being overpopulated with hens with no boyfriends !!!

Welcome to the forum, I think the reasoning is that males can fertalise more than one females eggs.

Thanks Jim, I'd feel much happier knocking a cock salmon on the head if there was definate proof that one male fertilised several females but I've read loads on the subject and am not convinced ! does anyone know of any literature that proves the point !

Parr, known as 'Precocious Parr' can also fertilise the eggs of the hen, nipping onto the redd under the nose of the cock fish. :z16

Just so, which suggests the best course of action is simply to put them all back. Makes sense to me :cool:

Read Henry Williamsons Salar the Salmon he writes about precocious parr fertilising the eggs, I worked in a hatchery and we used Precocious Parr to make up the amount of milt we needed for the job, so nature will take care of its own. I worked on Loch maree when they were trapping seatrout for breeding we trapped over 30 male trout and only 3 females
