Hi Dave,
I am not doubting anything you have said here as I have on several occassions tried to contact the fish food manaufactures and draw them into discussions on this forum from everything to dyes and nutrition... and Most have been very vague in even replying to me.....so I have no doubt that there is far more about the fish foods content that we don't know..then do know.,,Its frustrating to be sure.
I have even gone so far as to do my own comparisons , predominantly with NLS and Ocean nutrition pellets...nothing scientific...just observations....anyhow...currently using both.
Question for you?
exactly what contaminants are you refering to? Most toxins are stored in the fats and dark meat areas in the fish as far as I know...In the case of Omega, when they use skins, those are the more highly concentrated in contaminants.
They refuse to divulge the amount of "whole fresh fish" involved, compared to the scraps
