Seeing as I really enjoy reading everyone else's threads about their various activities, I thought I'd take the opportunity to add one of my own :)  I changed jobs about 18 months ago and now work at Kingston University, and have been very impressed with the biodiversity action group who organise all sorts of activities.  Last year I got involved in the ZSL eel monitoring in the Thames through the uni, and will be doing so again this year.  I've also been able to get involved in a habitat improvement project on the Hogsmill river, which runs through part of the campus.  This has been really interesting as I've learnt a lot about river management, and it was great to be able to do something that we can watch develop.  

Through the biodiversity administrator at Kingston Uni, I found about some free lectures at Birkbeck University in London. Unfortunately I'd missed all but the last by that time, but by a nice stroke of luck the last one was about river and wetlands management.  It's great that there's free events like that on offer, once you start to look for things like that it's amazing how much stuff is out there.  If anyone has the chance to get involved in anything like the projects I've been able to, I strongly recommend it, it's been very rewardning and I've learnt a lot.  It helps put things in context and show how things work together and impact on each other.

I've put together an article about the Hogsmill project if anyone is interested :)

Very nice project Sue, and thanks a lot for sharing. Only wish more stuff of this sort was going on over here.

Any idea what else is in there apart from eel and chub?

Excellent stuff! Say hi to Mr. Pecorelli for me.

Handily enough I'll be seeing Mr Pecorelli this afternoon for this year's eel monitoring training :)  The world needs more Joe Pecorellis!

I'm not too sure what other fish are in the Hogsmill, I'll see if I can find out.  I've a recollection of someone saying that the eel trap caught a gudgeon last year, might have been a topmouth one if I remember correctly as there was a degree of concern expressed. The Hogsmill doesn't get very deep but where it flows out into the Thames there are usually quite a number of very large, dark coloured fish hanging around under the bridge where people tend to feed the ducks and swans.  I'm guessing these are carp.  I did see a very large pale coloured one there a few weeks ago which looked remarkably like an escaped koi, but the water is quite murky so hard to be sure!  I'm told there are trout in the Hogsmill, but I'm not sure I've seen any.  I have seen a kingfisher flying along it (in the most urban area where both banks are deep concrete and it flows past the council offices!) and I've seen a cormorant come up from the Thames with a small chub in its beak.

The various rivers trusts seem to do a lot of good work, and a lot with volunteers.  I've found that having got involved with one thing, other things have come of it :)

I'm all trained up now for this year's round of eel monitoring, and took the opportunity to ask about other species in the river. Apparently there are barbel and stone loaches, and possibly roach. It turns out the large dark fish I mentioned in my previous post are barbel. I'm also told that chub have spawned near the area where we did the habitat improvement, so that's a nice development. 

I said to hi to Mr P, he was delighted with the greeting but also a little bemused as he couldn't place who 'Coelacanth' might be! 

As an aside, if anyone's interested in UK native fish I came across a nice facebook page recently, it was posted by ARKive.  It's a chap called Jack Perks https://www.facebook.com/UkMiniFishStudy?fref=ts

There are trout in the lower Thames (including some very big ones) and so it would be likely that they'd investigate tributaries. If you can get a picture of the large dark fish from above I should be able to ID them, although if they're hanging around where bread is thrown in then chub or carp are far more likely than barbel (barbel are sleek, and can be hard to spot apart from the coral pink pectoral fins). The pale fish is very likely to be a discarded koi or ghost carp, or one that escaped from a garden pond during floods further up, lots of carp in the Thames system. Bread is a great way to attract fish for ID, prewet it and chuck it in the margins, I'd be very surprised if you didn't get minnows as welll. There are thriving perch populations in the Thames as well, including some huge ones. For fish spotting, polaroids make such a difference, each year Aldi do some that are very good for £3-4, you'll be amazed at the difference. Amber lenses are best for all-round conditions.

I knew Joe from years ago when he was Curator at the London Aquarium and subsequently worked on the Biota project for London Zoo, must be over a decade since I last saw him. Next time you see him tell him it's Pete from Bolton Aquarium.

 

Didn't Jack post on here a couple of times? I know he was trying a crowdfunding approach, did a couple of things for Springwatch I think.

Cool mix of species Sue - it sounds like a pretty healthy system. :)

Yep Jack has been on here once or twice. We actually have plans afoot to do something similar to his UK projects here in Spain once I've got the Masters out of the way.

Apologies for not replying sooner!  Thanks for the info on the species Pete, I haven't been able to get down to the river for a few days but I had a trip down there this afternoon for another look.  Annoyingly the water is all murky and silty with the increased flow from the recent rain though!  Will have another try in a few days :)  You're probably right about the fish being carp and not barbel, they were definitely loitering in the known bread spot!  I don't recall seeing any pink pectoral fins, just big dark shapes.  Will keep an eye out for polaroids too - good tip!  I did get to see a cormorant in close up though, and lots of swallows swooping over the water for insects.  A friend is a lock-keeper nearby and tells me there are all sorts of things in the river, so I wouldn't be at all surprised if there are koi, especially after all the flooding.

A Spanish version of Jack's projects would be really interesting, those sort of views are not the sort of thing the average person will see and it's great to be able to get a look under the waterline :)

I have to email Joe later so will mention Bolton Aquarium :)

Finally saw them again today!  They were cruising about a bit further upstream in the Thames.  Not a good pic as the water was quite green, only had phone with me and couldn't actually see anything on the screen as the sun was so bright so was a bit 'hope for the best'!  The white one looks like it has two rows of larger scales running down its back.  They were all very chunky and at least 2-3 feet long.  There were about 5 or 6 of them, mostly darker ones but one medium sort of colour.  Escaped koi maybe?  Or perhaps a bit of a hybrid.fish-in-Thames.jpgImage Enlarger

The pale one looks like a ghost koi?

It does a bit doesn't it, I'd guess it was an escapee at some point, or else someone in its ancestry was :)
