Has anyone addressed this issue? Too me this is serious enough to determine whether or not I pursue aquaponics, although of course I understand that when hungry enough one will eat just about anything. Plus, the vegetables are fine.

Farmed fish do not have the correct balance or so I've been told so is it possible to adjust the feed to correct this or is it an environmental factor that can't be replicated?

Sorry if already addressed I just signed on and don't see a search field.

Some may see this as trivial but I can assure you some of us do not.
