      Will fins grow back to normal size on fish once cause is ameliorated?

      O.K. not koi but you guys have been so helpful and knowledgeable, a lot of things I've learned here have helped me tremendously with other fish species I hatch and raise.

      I have various trout species in net pens to separate them from the larger predacious trout until they are large enough to release freely swimming in the pond. One of the issues with keeping fish in net pens, tanks, and raceways is fin erosion due to nipping by other cohorts or wear on surfaces. This is especially true with aggressive species like trout.

      So for those of you that have had fin issues with koi for whatever reasons, have you found when the conditions that cause this are ameliorated do the fins grow back as they were originally? Starting this fall these fish will be free swimming I the pond for the next two years.

      Here you can see fin erosion of the caudal fin in this steelhead trout. All fish are healthy otherwise and growing fast. 12 to 13 inch steelhead in 7 months.



      The two net pens I have these smaller trout in until release this fall.

      The risk I took was calculated, but man am I bad at math!

      They will never be good enough for show but good enough for the smoker!

      Are you sure? That's what I'm afraid of. These fish are not destined for consumption.

      No experience with trout. With goldfish my experience is if the damage is minor it may repair to where it looks nice. If the damage is more substantial and into veins repair will happen but complete repair is less likely.

      How much percentage is missing?

      Here is an enlarged version (original size photo) of the fish in the first post. Hopefully you can see the erosion of the caudal fin better. Maybe 10 to 15 percent?
