Backyard Aquaponics
A place to discuss aquaponics

Can you isolate the smaller ones inside the tank somehow? Not knowing what sort of tank you have, but could something like a bucket with holes in it. Then see if they'll eat in there?

Not a bad idea col, I'm running just a single ibc atm

Water temp this morning was 9c I feed twice last night and again this morning

you said the little ones were taking pellets fine didnt you?

Wouldnt we expect bullying to show some scale loss, some fin nipping or some damage? or is it just the chronic stress killing them?

I would have thought so as well gmturner but for the life of me I can't think of anything else that could be doing it

My cod won't eat when I watch them. They just sit very still and hope they are not seen. I know they are eating, because the food goes missing, but I don't know which ones eat.

Some of my smaller ones, I don't think they eat much at all, but I can't know for sure because I can't see them eat.

Have you seen the smaller ones ever eat?

Yeah the all activity feed at night time , I have up the feed rate to twice at night and once early morning see how we go in the mean time I'll monitor water conditions and temp
