I told my mate in the Netherlands who recently took up fishing that his latest catch could well be a leather carp. Was I talking ship?

Sorry fella, I think you may have been. A true leather, from an angling perspective, has no scales hence their rarity, you can see the row of scales on this one along the top of the back. There's no evidence of the punctuated dorsal, or the other characteristics to suggest its a genetic leather 👍

I think most people will listen to what Simon Scott has to say on the subject

If this is wholly wrong I apologise, however many years ago I was with a bloke who had caught what he thought was a leather carp. When doing the photos Mark Bryant showed up in the swim and when we were discussing whether it was a leather carp or not, he said the one way to be sure was to look at its bum hole, as a true genetic leather has four veins that are around it that travel in to it, under the skin.

Could be BS but I remember him being very adamant at the time....

You need to check the anal fin, not it's a-hole You're looking for a ray count of 4 or less. Can't recall who showed me that, but it was about 20 years ago. A leather will usually have the odd scale on it, but not many and usually they're near the tail or on the back. I've caught very few that were completely devoid of scales. Once you know what you are looking for, it is easy to identify them. One water I am on at the moment has about one in five leathers, with all three 40's being leathers. I much prefer them to a common, but I'll take a fully scaled mirror all day long for looks. Had one of 39 recently, incredible looking thing. What a privilege it was getting that one, even though it usually goes over 40, I wasn't too unhappy about it. Now looking for a second date with her in the autumn

I seem to have forgotten about sexing a carp dirty minds What´s the easiest way, to remember ? Didn´t that have something to do with the shape of the bumhole ?

Wonder if i heard right, but did Simon say, that crossing a fully scale mirror with a zip linear, you get :-

25% fully scales
25% linears
25% leathers
25% commons

So originally, commons are genetically a subspecies of mirrors, and if they continue to successfully spawn, naturally crossing with linears or leathers, then the majority would be either fully scale or commons So leathers are infact subspecies of mirrors. Seems like leathers have drawn the short straw genetically, having reduced fin generation & and easily susceptable to oxvgen depravation, and lower resistance to fighting off infections.

All carp were originally bred from commons, selection for less scales produced mirrors and ultimately a few leathers.
Why it bloody matters to anyone is beyond me. A fish is a fish. Some are prettier to look at than others. That shouldn't make the uglier ones worth less as a capture than any other. Rant over sorry.

It mattered because the fewer scales, the easier it was to cook


Must admit I can only recall 2 perfect leathers I have ever caught; a 15lb fish from Taverham, totally scaleless dark leather, and a 24.12 from Ardleigh Reservoir, angry, grey prehistoric looking fish, real special.
Are you sure?
