We can have an index of biomass that relates with a limited number of ages. The loop in ADMB would need to go between the age range on the index and not on the stock. The problem is that we're identifying the index by the number of ages it has. We could overcome this by creating an extended index for biomass cases, which would make it easier for other bits of the code.
