Why the F1 strain of carp was ever concieved and why it was stocked into so may commercial ponds in Engand?
Can someone please explain

I don't see the point unless they taste better. :wh :w

I know the term F1 is from the genetics world, but it's such depressing way of describing a living creature.
Couldn’t we at least call them something, anything, more interesting than F1s. Crarp? Crommons?

I've never fished a lake that holds F1s and don't intend to.
Each to their own in angling. If that's what someone wants then good for them. I would've absolutely loved to catch fish like that when I was 12 years old.

Yep, they rarely go much bigger than 4lb, which is a nice size for the pole men. Big enough to build a big weight quickly but not so big as to be hard work when fishing a pole. The fact that they keep feeding in the harshest of conditions is a bonus for a commercial venue too.

Feed all year round and fit in a keepnet then, how convenient.

'Compact', please!
I believe they can't breed either so if they get into the wild rivers, when they die, that's it, no succession.
However, 'Nature will always find a way' - quote from Jurasic Park the film.
Thats why the grow quick, no need to expend energy producing egg/milt and then knocking the hell out of each other whilst spawning.
I believe they sell carp in France that can't breed either now, again for the faster growth rates

F1 of filial one crosses is the name given to a particular kind of hybrid.
with reference to aqua culture the F1 hybrid offers a phenotypically regular product, that is you can produce large numbers of fish that are consistent in size and appearance, a homogenous product.
When 2 brood animals of a known pure lineage are crossed the outcome is predictable, aqua-culturists can therefore produce fish with predicted attributes (size, build, colour, behaviour etc)
F1 hybrids also tend to be sterile, this has several advantages (all be it contentious ones)... as rightly pointed out they have little sexual imperative in these fish so they tend to focus on the business of eating and growing, because they are sterile they also create a sustainable business for the aqua-culturist as they will not generate naturalised populations ans stocking has to be maintained artificially, they also tend to be generated using modern heat shock methods which insure the vast majority end up female... which means bigger fish for folks to catch as female fish attain bigger sizes than males (generally speaking)
now here comes the rub... whilst there is a great argument ofr the introduction of F1 fish, they dont dilute wild blood lines and all that... because they dont get distracted by the spawn, they do tend to out compete natives for food which may lead to their indirect demise
just my $0.02 YMMV

So if these F1s have been bred with the matchman in mind, would it be correct to assume that all fish from their point of view are valued as mere points scoring devices like a single bean count, or a number on a dart board.
And that untimately they would want all fish to be identical in size, say just swingable to hand and preferably have zero fighting power.
Hells Bells what is fishing becoming?

I rather think that you are taking it to an extreme that doesn't actually bear close scrutiny. Even match anglers of my acquaintance like catching bigger fish, just not too big. While F1s don't grow particularly big they are generally too big to swing to hand when they are stocked. F1s aren't usually stocked exclusively, where they are, it's generally to perk up the chances of catching something other than roach, gudgeon and perch in winter matches when the temperatures stay low.
I can well understand the distaste for hybridizing in this manner just to satisfy some customers. However, don't try to make out that it and matchmen are something that they aren't.

What I stated were purely assumptions based on what I see as factual.
I would hope that matchmen are not all like that.
Although years ago I was involved in a discussion on what is valued by matchmen v specimen hunters. The matchman put it all togther by saying that he would rather catch a 2 1/4 lb skimmer than a 2 lb roach, any day.

They are no more or less defensible than triploid trout; they pose a year-round technical challenge for those who must get out and catch something.
And some must; school holidays all conspire to fall when fishing is at its worst/least pleasant/closed, others "need" to keep their match techniques up to scratch, journos have features to write, and some people are so busy that when the chance comes to dangle the angle, they simply cannot afford to waste it scratching about for fish that may be spawning/hibernating/elsewhere.
Even the minted, the seriously specialist and the traditionalist need the occasional session just getting some bites. Or so I'm led to believe...:wh
