Terrible pic, I know, but all I have at the moment. So, the water in my pond has cleared enough lately for me to see the fish pretty well around the feeder at feeding time. What I just noticed is that about one third of all of the Bluegill seem to have this white fungus looking stuff along their pectoral Dorsal fin. It is nowhere else on their bodies, just along the top. Any idea what this is and why it showed up?

Edit Reason: Wrote pectoral instead of Dorsal

I've never seen anything like that. Are you sure it's on the pectoral fins? Kind of looks like it is on the dorsal fin in the picture.

Yes, dorsal. sorry. Was in a rush and screwed that up. Thanks for catching.

One factor in conditions similar to this that I've seen have been high stress. But this can be from heat stress 2 months ago-probably not recent. Only thing I know of that you can do to help is fish for them and give each fish you catch a salt soak.
Treating the entire pond for fungus affects EVERYTHING.

My larger CNBG were devastated by fungus in fall 2017, covered about half their bodies.

I agree with Snipe that there is a cause and effect. The cause my still be there or long gone.

Not qualified to have much of an opinion, but I wonder if there could be a bacterial infection involved. Do you feed your fish? If so you might consider lacing the feed with an antibiotic. We need one of the gurus to chime in.

Yes, I do feed them daily. I also aerated all summer, running only at night. The only issue that I've had was back in May when I first started up my aeration system. Even though I started very slow, I still had a pretty good fish kill (approx 50) consisting only of large bluegill. Is it possible some could still be feeling the effects of that? I'm really puzzled because other than that one incident in May, the pond has looked great.

I see it here almost every year. A shallow pond with Summer surface temps in the upper 90's hit's my CNBG hard.I rarely see it on smaller fish.

In your experience, does it usually resolve on its own? or is it a fatal condition?

Over time, it will resolve.. The end result may or may not be what you want. One of the biggest factors in stress related events is over crowding. There are certain treatments that "could" be added to the water but it affects every organism in the pond, including beneficials.
You see this in the larger fish but it also affects the youngest as well-but you may never see them or the mortality of.
You CAN help this, even though to a smaller scale, by catching and doing the salt soak as I said above. It'll kill the fungus on every fish you can dip, and the more you can dip before hard winter, the better they will look next spring.

The CNBG in my hatchery pond got a fungus early this last spring, and it pretty well wiped them out. A few hung around for several months, but ultimately died. I haven't seen the same with the white tipped CNBG, and I never saw any floaters.

I have successfully treated various bacterial infections in my cages with antibiotics designed for livestock - add it to feed and over the course of two weeks the infection was knocked out. Mixed water and AB and fed moistened, sinking feed to encourage fast feeding. Use gloves when messing with the AB and medicated feed.

Thanks guys. Teehjaeh57, Have you ever run across this white dorsal fin fungus before? So bummed since I thought everything was going great. I guess I'll see what happens. I'm not in a position right now to catch and treat them, so hopefully, the condition will resolve on its own. Big cold front rolled in last night so I went ahead and turned the aeration off until Spring. From everything I've read here, it doesn't do much good once surface temps get below 65 or so. Again, thanks for the advice everyone.

Yes, I've seen fungus develop on transported fish especially where they've lost scales due to handling issues. That seems to be the origin of the fungus I have dealt with, but I've also seen it in the fins. Infections are obviously much easier transmitted through caged fish, so that's why the AB treatments were so critical in my cases. For pond fish I wouldn't lose too much sleep - you could still hand feed AB medicated pellets and take your chances that the infected fish are getting some, but that is a lot of effort. The strongest fish will make it through this episode for you, some natural selection happening, so that's a bit of a silver lining. Keep your eyes on those fish, catch some if you can, try to identify if it's getting worse or abating. Post photos, we are here to help.

JKS, if you do get to catch/trap fish, with fungus I would HIGHLY recommend you treat those you can with a salt solution, it only enhances the overall health of the fish. It cleans gills, kills fungus spores and stimulates the natural slim production process. TJ is probably right in that nature will rebalance the situation but you can maximize survival with a salt soak of anything you catch.
