    Default Severe Lice Damage to Wild Salmon - Photos.

    Over the past couple of days I've been helping friends legally move spate-system salmon from a sea pool further upstream to fresh water. It has been dry here for eight weeks or more and the summer fish has been waiting some time to run the river, moving in and out of the sea loch with each tide.
    Unfortunately there are salmon cages in that sea loch not two miles from the river mouth and the wild fish are now carrying a heavy lice burden. Some counts by the scientist present ran to over 500 lice on fish around 4 - 5 lbs.

    A dead fish showing severe lice damage:

    Heavy damage to the head and dorsal fin on this living fish:

    This fish below will hopefully survive now it is in fresh water. The lice will have dropped off within 48 hours. Every little brown bump is another parasite grazing on the salmon's skin. I even saw one attached to the lens of an eye.

    There's an album of photos from the first day here on my Flickr site.

    I'm not going to rant. We all know the cause.

    And that despite all the poisonous chemicals they use to try to control them, an absolute disgrace, the powers that be should hang their heads in shame.

    Looks like the thousands of wrasse they are "stealing" from the south of England to eat the sea lice are a waste of time then.

    When I made suggestion that we might contact the fish farm companies to request help someone remarked that, "They might, for P.R.''
    I said, ''The should - for shame.''

    We were able to net and transport around 75 salmon, 8 of which were found dead the next day. However, given that 100+ dead fish had been removed from the sea pool over the previous days and the atrocious condition many are in, I feel that was not a bad mortality rate. My main hope now is that they recover to spawn. If we have a hot August there could be widespread fungal disease amongst the weakened fish with flesh wounds.

    There had been a small lift in the river before we started on the second day allowing the smaller salmon to run of their own accord (thankfully), so we netted fewer but bigger fish, those too large or exhausted to run the stream. One known fish we missed was a rare Springer estimated at around 20 lbs - a monster for our waters. Someone might get a bit of a shock there this season!

    This is the root of the serious wild migratory fish problems where open cages are located.Returning smolts are plagued with lice and die.Pacific North West have been fighting for years on this very subject.In uk from what I have seen on TV every time someone gets close to exposing the reality it seems to just fade into obscurity.I know there are other reason for stocks decline but this is the ''biggie'' as same story everywhere these open cages are located.Most recent UK TV showed dumpster trucks taking away dead farmed salmon.I am afraid the corridors of power are ducking out on this appalling very obvious and serious issue.Not a quick fix and an expensive one to install closed facilities.

    You could also ask the owners of local estates that sell salmon/sea trout fishing and also get money from fish farming for help. I don't know about the system you were working on there but many estates want to have their cake and eat it when it comes to salmon fishing and salmon farming.

    Anyway a great effort in the face of a terrible situation.
