What fishes live where?

Y'all might find this of interest.

So if you want to know "Are there any dace in Yorkshire ?" you can play with this map instead of pestering Gozzer

 

Couldn't find any Burbot though

Amazing. Apparently the Severn at Trimpley only contains perch and the Stour at Kidderminster only contains carp, pike, dace, sticklebacks and gudgeon.

Seems accurate, apparently most of my swims contain nothing and I can certainly verify that.

I did!!! ... pretty much on the doorstep, too, somewhere in the vicinity of Durham!

[Vagabond]

Now I've had a bit more time to play with it, it seems pretty useless on fine detail.

 

Lots of waters in East Sussex seem to have nothing but pumpkinseed !

[Worms]

Pretty accurate in my local waters....apart from a lack of pike!

 

They've obviously all been taken and eaten as they're the only fish we're allowed to eat now!

[gozzer]

I can't get it to load, so it's useless to me.

 

 

Oh, and before you ask, yes, we do have dace in Yorkshire Dave.

 

John.

Computer says No. I think the server has encountered an existential quandry (happens a LOT on the NR system)...

 

Now I'll never know what I'm not catching!

Vagabond,

 

What value would this information be - even if it were accurate?

If accurate, (which, unfortunately, it isn't) it would tell us as much as any other distribution map - not necessarily a true distribution, but the distribution of what has been observed.... and of course such maps can go out of date fairly quickly - particularly in recording introduced species. They vary from extremely informative to virtually useless - depending upon the quantity and the accuracy of the data entered.

 

I have seen plenty of "distribution maps" of a number of organisms compiled by a few well-meaning naturalists - the funniest was a map of British leech distribution (there are about a dozen species or so)

 

The map showed 5 species just west of Glasgow, about 8 at some location near Nottingham, and almost a full set in West Sussex. It was of course, simply a map of the location of the only three people in the UK that could recognise the leeches and were interested enough to record them!

 

On the other hand, British amateur botanists (co-ordinated by a Cambridge don) compiled an excellent distribution map of British flora way back in the 1960s. It covered virtually every 1 km square in the country It is very valuable as a baseline in determining if any species has since then been in decline.

 

Simiularly, there are excellent distribution maps for British birds - accurate because there are a large number of well-informed birders providing information.

 

Unfortunately the same doesn't hold for fish - I was quite disappointed when I looked closely at the fish map and realised how poor, how very poor, it was.
