With the decline in whale stocks, more krill would presumably have been available to the remaining whales allowing faster growth and attainment of sexual maturity at an earlier age (Fig. 12). Mitchell (1975) has speculated that following the reduction of Southern Right whales in southern waters, Sei whales extended their range to utilize food resources previously unavailable to them, due to competition from the Right whales. This is reflected in the earlier age of Sei whales at sexual maturity.
