It probably doesn't matter for the average angler and many venues stock F1 hybrids on purpose. What matters is the pure genetics from a biodiversity and conservation standpoint.
Mr john Fishlocker says 80% of flatfish are mix breed and genes and why flounders are often found with red spots from plaice.. how accurate is his theroy and how come i dont see any spots like such seen on Dab pics.. plus if this is so would this happen with Turbot and Sole that Flounder, Plaice and dab share waters with?
Good vid jack .Gibel carp I use these for example there eggs can be fertilised by most cyprinids . Now-they say in Europe the off spring can breed and after few generation look gibel carp again with no indication of hybridisation in there linage . I breed fish for long time and I use Central American cichlids for example you can cross pretty much all of them usual the off spring males are infertile but not always and females stay fertile . What I do beleave is closely related uk cyprinids off spring from hybrid pairing can successfully breed . I no of two pools containing king carp and goldfish they natural produce what look like f1,s ,. And with demise of the carp what’s left does spawn each year .to conclude I beleave as in Central American species ,cyprinid hybrid females are fertile for the majority however males are not . Meaning the said females can still produce viable eggs and have them fertilised by a fertile true species male ..
It matters with rare and endangered species. For example, crucians often hybridise with goldfish, common carp and gibel carp, so the true crucian species is in decline and threatened across Europe. Silver bream are another species that are scarce (or perhaps under-recorded) in the UK, and they freely hybridise with bronze bream.

I was catching some huge roach... or so, I thought! A friend showed me that they were, in fact, roach × bream! Great fish and loads of them!

What was the line in Jarrassic Park? Something about mother nature finding a way?!
Enjoy your vids so I’ve just subbed 👍🏼🎣🍺
@@mattgoodchild8215 cheers!
Serious issues with crusians n goldfish ! Easy to tell really! Id say its obvious! . Great video tho !

Isn't Silver bream (Blicca bjoerkna) a roach X bream ?
No, separate species
Silver Bream are their own independent species, and very rare in the UK so a worthy prize if you come across them
The only time it really matters with with record fish, but do they really matter.

@@portcullis5622 Didn't think of that. Very true. Although I think the Silver Bream is under reported as an awful lot of anglers call the hybrids.
