[greg]

Hi All,

See the attached pictures.... I dunno what this is OR what if anything can be done?

Leeches ?? never seen this before,looks like small hemorrhage's bites of some kind

[Duncan]

whats the overall symptoms of the fish other than this

like i have taught you discount what it isn't and whats left is what it must be however unlikely

so its not a parasite its unlikly to be bacterial but it could be i suppose im gonna assume its not water related or more fish would show it and you water im betting is spot on

so im left with a vitamin problem or viral

whats the frame of the fish like? is it bloated? how fast did this appear and are any other similar ?

Duncan,

The koi behaves perfectly normal - feeding well.

Not bloated or out of shape

it is male and is 8 years old

Water is better than it has ever been IMO. (PH - 7/7.1, TDS 110-120, KH 2, GH 2, Amm - 0, Nitrite - 0)

In terms of other koi there is one other with hints of it. But they are again very symmetrical in placement - this koi is female though. There are 15 koi in the pond in total.

It was there a little bit (much less) last year but disappeared over winter but has returned this year but worse (no other koi affected last year) - I did wonder if it was related to the koi being male (infected tubucules?)

The other thing is if you disturb them they bleed.

Blood spots so are we talking hemorrhage's ? not seen this before stings or bites ?? injuring its self on something ??

sorry mate forgot all about this i have spoken about this with people in the know and they have drawn a blank

as lee said its for all the world like the puncture marks where a parasite has been feeding but you would have seen this argulus would be my guess if there was one

so im going with some kind of virus of which there are many many fors the cuase localised heamoraging

in any event you may have to send samples of to a lab to get this one identified i dont think its the kind of things that a pond side diagnosis is possible

my advice is talk to Paula she has the facility to deal with this

Cheers Dunc,

I have mailed Paula.

OK,

An update...... Paula felt could be a number of things and left me with two options.

i). Try an experiment of injecting the koi with a course of baytril (10%) at 0.1ml per KG with 3 clear days between the injections.

ii). Take the koi to her and she would take blood samples etc and try to be more accurate.

She felt at this stage it could be either Viral or bacterial but was more concerned about the hemoraging in the fins rather than the head. I opted to do the first option as it was something i could do myself immediately with no hassle and with nothing to lose (as such).

Note:- In between the forst set of pictures and this next set i scraped and topically treated the head area of the koi only with mercurachrome to see if it had any effect. In short - Nope!

However today upon netting to carry out the first injection i noticed that the hemoraging in the fins had practically gone.

Hi Greg,

Well now that looks good Greg did you still inject

[greg]

Gazza,

Yes i did - having taken the trouble to seek out opinion i decided best to follow it through. Fingers crossed it will tidy it up 100% will keep the thread updated and Paula has asked to be kept in the loop.
