Double Sided Flounders (mods any chance of making this sticky?)

Well-known member
After seeing Tony's mention of catching a double sided flounder I remembered that I still have a contact email for the lady (Margaret) at Newcastle Uni who was doing the research into these so pointed her to the thread. As she's not a member here she couldn't post but is interested in gathering numbers and info because the doublers seemed to pretty much vanish a while back.

Can we get a sticky thread on here for people to log their flounder catches this year clean and double sided so some kind of percentage can be worked out? I can point Margaret at the thread so she can keep an eye on it for updates.

Cheers!

i have caught one down hebburn before sum man told me this is a freek flatty as so it was abnormal from the rest is this true
 
It happens on and off mate, don't think they're fully sure what causes it ie whether it's something getting into the water affecting them or just an abnormality that does the rounds now and then. Go through years where there's loads of them and then years where you barely see any at all.

You tend to see variations from a few patches of the "dark" markings on the white belly, like blemishes. Then you get completely double-dark sided fish, sometimes with additional eyes, looks like 2 flatties glued together! I think double-white sided fish are far less common from what I've read.

Does denmark count? cant hurt to mention:D got one today, not a total doubler but it has a lot of dark on the white belly. it was thicker than a normal flounder. lots of muscles:D pic in gallery.

Yeah it's Dove Marine/Newcastle Uni have been researching for years, was a few requests put out for any info about them but then it seemed to go quiet - i found some old mails and contacted the people to see if they were still interested, they were hence this thread was kindly put up.

Kela - cheers for the info, nice one.
 
if you do get any could you post it here, where and when you caught it. for some reason the areas that for a long time produced thes fish no longer seem to and that goes for the Wansbeck, lads who still fish and are aware of the studies have caught very few, wherer at one time there where loads. Another interesting thing is that the number of diseased flounders has dropped to almost nil. I inspect all the flounders at the opens etc and have seen no double sided or diseased flounders for a few years. i am still in contact with the Dove, looking into other aspects of flounder life. so if you let me know precise info I can pass it on. All info appreciated.
 
I've caught a few of these when I've had kids out fishing. One off Blyth Pier, one off roker pier and one off newbiggin beach (both brown with white blemishes on bottom) and one at Horden beach on Thursday (fully brown both sides). None of them had extra eyes though
 
Caught a flounder of roker pier late summer similar to pictures posted the back 1/3 near the tail was double sided, didn't think much of it to be honest, I've also seen a Dab caught by a friend with same sort of semi double sided colouration.

Sorry no photo's fish was around 30-ish cms
