It all depends. For the grass carp are there weeds for them to eat or are they surviving primarily on pellets? Are we stocking them for weed control or just to have some big fish to occassionally catch as a surprise?.

Are you going to monitor the condition factors of any of these fish? Is it a concern? Are you looking for decent growth or just normal survival?.
