While otters may not eat all your fish (they won't) they can and often do destabilize the population balance.
Its May and BG are getting ready to have a major spawn (in many areas). Feeding can slow then.
As far as I can tell, otters did eat ALL my CC, about 25 big ones (3-6 lbs) in one pond and about 50 just under two pounds in the adjacent pond.
