Andy the trout farmer, more in tune with feeding fish than myself....
Some points though, since when has too much protein been bad?
Isn't it true that excess proteins that aren't utilised by the body are passed through as waste?
Too much oil?
I've commented on this in the past, I have never seen a carp with an exploded liver and cannot understand how ingesting too high a concentration of oil, will cause the excess to stay within the fishes body and not be passed through.
Everyone I've asked has not been able to explain this, I've only heard hypothesis and rumour, normally from commercial fishery owners.
Can you explain this to me Andy, you been to Sparsholt, you've got some knowledge ?
