where do they stick the arial?

Something of interest....I think they've got a new batch of radio controlled barbel on the Ouse now as well :D

The pictures may answer to your question.. here's the latest on the radio controled barbel on the Ouse.
Karen Twine's PhD work over here on the Gt. Ouse - we managed to collect 25 barbel between 5lb and nearly 16lb from the river last week, and tagged 20 with radio transmitters.

The surgery was performed under Home Office licence, with anaesthetic and utmost care by experienced fish health specialists. All fish appeared to recover well and swam off strongly. Most have remained within a few hundred meters of their release points, apart from one cheeky individual who decided to swim 5km upstream on the first night and was later joined by another fish. Overall, we've had some very interesting results so far in just one week.

We are out doing daily tracks at the moment, with some 24-hour sessions planned soon. The tags will last for two years, so we're hopeful for a valuable look at movement and behaviour over that time, along with several other spin-off investigations related to spawning, over-wintering and predation pressures.

By the way, anybody who fishes the Ouse and wants further information, or catches one of the tagged fish should get in touch with the EA. Here are the contact details

Sounds a really interesting piece of research to me.
 
I wonder how many otters they are now accidentaly tracking which have eaten the transmitters thinking they are vital organs?? :)
 
Thanks for that Pete.

Where did you find the info on the tagging work? I've known about the research for a while but have not been able to find anything out about it.

If you e mail the EA officer he will keep you informed. I got the info from Pete reading of the Barbel Society as the Barbel Society are involved in this research, also all the local clubs were invited to take part and many are.
The location of where exactly the fish were taken and where they are now will of course be confidential for what I assume people can see are good reasons.
Salmon have been monitored this way for some time as part of various research projects, it is the first time AFAIK that such work has been done as part of a PH d in the UK on coarse fish movement. I am sure the PH d student would also be willing to talk about her work, as one myself (not in fish movement, but angling and art, getting any help in a research project is important, particularly funding!
There is actually a live web site somewhere, I'll try and look through by book marks to see if I can find it, which shows the location of tagged Salmon on one particular river! Not to sure that is a good idea...makes locating them a little to easy;)
One of the things the research is looking at is the effect of predation, so if any have ended up in otters we should soon know!

If you are really interested

The most recent published work on radio tracking of coarse fish is

Which if you have access to JSTOR you can get on line or try your library.
This was carried out in Australia tracking Golden Perch and Carp in the Broken River.
It gives an interesting view on just how far these fish move, at what time of day that movement takes place and their behaviour after capture and release by anglers.
It showed the massive variability of individual fish. Perch in a 50 day period travelled away from the initial release site anything from 0 m to 7480 m and Carp 0 m to 3090. In each case more than 50% that actually travelled did at some time return "home" ie the point of initial capture. This outside of the spawning season.
Given that it is thought that barbel travel much more than most coarse fish, which is why they can sometimes disappear entirely from a bit of river, what happens on English rivers will be really interesting.
 
Skip Bridge Weir

As a result of the original paper, Skip Bridge fish counter was removed, I think that only leaves a few dozen weirs left on the Yorshire rivers which date back to Victirian times. Even with it removed a double figure barbel on the Nidd is like finding the proverbial stuff from rocking horses
 
Thanks again Pete.

I'm a member of 2 angling clubs which are participating in this study so Im really looking forward to recieving some information about it.

Those fish counters started ticking over like no bodies business,once Barbel are in the water. The same barbel going up and down a few times got the Salmon anglers all excited!
 
Can't beat a bit of history....however the mentioned EA officer I have no trust in him regarding looking after us anglers....used to be in charge of my local consultative and did f all round my way and when he left I thougt well done.

Whether sticking tansmitters up a barbels arse will do any good for us lot will remain to be seen.... so speak to an EA officer who listerns...not just one who walks the walk then moves on with no answers other than creating radio controlled barbel..when at the end of the day we no they ****ing swim along way

Cheers
