A number of dead sea trout are being found in the upper Tyne catchment. I am in contact with the EA about this - just wandered if anybody had their own thoughts?

The sea trout have probably started spawning in the upper tributaries. Probably a casualty, many of the c0ck fish die after spawning, less so with sea trout than with salmon, but still a significant proportion. The fish does look like it is spent. I know it is quite common to catch sea trout kelts up this way during the last week or so of the season.

I'm not sure about it being a spent fish, a lot of the old cock fish down here are that shape anyway. It should be easy enough to tell by opening one up. It is very rare to find a dead sea trout kelt down here, I assume it is unusual on the Tyne too?

Keltus deadus.

The hen fish certainly has not spawned. There is some evidence of fungal infection on the anal fin. Possibly furunculosis, quite common as fish approach spawning.

Looking at the body shape of the hen I see what you mean, but don't think it is that straight forward, there is visable evidence at the anal vent. The hen may well be incapable of spawning due to worm damage and then died due to exhaustion but then there should be more damage around the anal area and not just badly damaged anal fins (there have been a few of these suspected cases), but perhaps it has just been caught and not been able to recover. The anal marks are nothing special and typical of fish that have been lying around, with perhaps the upper oval area being out of the water. Marks around the hen's anal area, tips and roots of fins are typical of kelt after spawning time, but then the colouration is wrong for such. Not surprising to have spawners with recent frosts and consistent low water. Looking at the gravel around the cock, it is certainly in the right area.

Andrew Do you know how many fish were found? I think there were up to 10 found like this in a short section of the river. The EA have the photos now for their perusal. I had a chat to them at lunch time so will let you know their thoughts.

hopefully not the result of poaching or pollution.

They certainly don't look like kelts and there isn't much fungus/disease, a mystery, maybe the Alston boys have been topping up their freezers, don't think the stretched EA will have anyone watching that area!
Is there a big stock of fish in that area? That usually causes stress then disease/fungus.

Whatever the cause(bloody Waste) Hope you get to the root problem.

I put ' River Tyne' into Wikipedia the other day and was surprised to find a quite thorough report. In the fish stocks section it has a piece on Sea trout being found dead every year in this section of the South Tyne- It suggests only 50% have spawned...
I don't know if this is the same area or not but here is the quote.
'Every autumn after the first frost large numbers of dead and dying salmon and sea trout are found near the mouth of the Newbrough Burn in the South Tyne. Of those found dead since at least 1985, more than 50% had not spawned.'
