I guess with plenty of LMB there never would be a problem, but I do hear regularly on this forum that once the GSH reach a certain size that folks are recommending catching and removing them. I wasn't sure why that recommendation unless it is that they are consuming too many young fish of the more desirable species (like those who are trying to establish YP in a YP/GSH only pond?)

Dr. Luke, it is a common problem that I'm sure you face often, men in their 40s who desire no more children and women in their 30s and 40s who agree but who do not want to do anything about it for the next 2 decades, and then the problem is somehow up to the men to fix for them.... but I digress.

I would want to keep some ongoing GSH reproduction every year so it would be helpful to know if the parasite was doing real harm or not.
