Report of the International Whaling Commission,
The proportion of food actually required for growth relative to maintenance after the first year of life is very small, <6%, regardless of growth rate. The proportional extra food energy required to effect faster growth and earlier maturation in minke whales is similar to that required to produce the observed changes in these parameters in fin whales Balaenoptera physalus. The relative total costs of pregnancy and lactation in minke whales are also similar to those in fin whales, implying that the currently proposed annual calving is energetically possible for the minke whale.
