After heavy rain fall, my larger Koi are jumping up and could damage themselves on the rocks at the side of the pond. I've had the larger ones about 5 years now and they've never done this before.
Is there any cause for concern? I'm not what you would class as an expert Koi Keeper and wondered if there might be something wrong with them.
Many Thanks,
Lesley...

| If koi our jumping it is sometimes a symptom of irritation, then it will usually be associated with scratching and flashing activity in other koi rather than being restricted to an individual fish. Irritations can be caused by parasites, attached to the skin or gills by. It is possible to verify parasites as the cause by carrying out a skin or mucus scrap. If a positive identification is made, then proprietary medications are available to satisfactorily treat the problem. However, if parasites are not found, then it is likely that fish are experiencing an irritation from poor water quality, with nitrite being a common offender. Hope this Helps Marc

| Hi, I'm new to this forum but have been adding comments on another forum of late. I agree with Marc but one thing you forgot Marc is that if you have high nitrates then stop feeding straight away, don't worry about not feeding as koi can live happily without food for around 14 days. Once you've stopped feeding, start doing water changes, at least 10-20% change every day for a week.Each time do a water test. I forgot to mention before changing water do a test just to see what the parameters are. You might find its not the water.If its not then I would catch the jumping koi and do a scrap and check it under a microscope.If something is found then treat, if nothing is found and water is ok, then theres only one other thing I can think of, and thats due to the rain perhaps the water has colded down and this has irritated the fish or I have noticed sometimes with mine they jump for flys hovering over the pond. Hope this helped stokie

Totally agree with the above, however, atmospheric conditions could also have an effect on the fish. When it rains oxygen is sucked out of the water and returned to the atmosphere and therefore oxygen starvation comes into play. It could be that the fish are rushing to the surface to gulp air. If the fish are only "jumping" when it rains and are not doing this during "normal" conditions and there is no evidence of flicking and flashing then i would suggest that this is the cause of the problem. A large airpump may help in this situation.
