I hope some of you can help me with info. I have been helping out on the two river's I live next to, the Nethan and Clyde. There has been a lot of good work done helping the Salmon and Sea-Trout for many years, this year has been a good year for fish returning, but they are coming back with a Red Vent, I looked inside at some of the fish and could see that they had a high worm count, about 1.5" inside the vent of the fish there was a black area. ( did not look good ) Looking at the worm it is one of the round worm family, to me it looks like the Strongalosis worm found in Grouse, a worm that thrives in wet years. Out of about 20 fish I think only 4 ( 10lb+ Spring fish ) did not show signs of this Red Vent. All the Grilse I seen had signs of it. I think about 85-90% of fish caught in my area had Red Vents. Does anyone have any info on this, or does anyone know if the infected fish can Spawn ok. If they cannot, our river will be thrown back at least 10 years.

Hi Willie Gunn,
Thanks for the reply mate. I just hope the fish can spawn. Some folk say they will be ok and others say the fish will die, time will tell.

Hi Neptune,
Thanks for the reply mate, I have read that one, and many more like it. I have looked at the worm under a microscope myself, it looks like it could ba a nasty wee fella. But what I dont know is, if the worm count is so high will it shut the vents and not allow eggs to pass threw the vent when spawning. We have a lot of fish ( the most I have ever seen ) in the river and burns waiting to spawn but have been unable to see the results yet as there has been high water on our river for a few weeks now. And with it raining just now and more on the way it could be all over by the time I get to look at the Redds. As I said to Willie Gunn time will tell.

The parasite is the nematode worm Anisakis sp. All the up to date evidence is that the fish, despite some early indications, are in fact managing to spawn OK.
