    Though South Georgia and Bouvet Island are located at the same latitude, the growth and maturation rates as well as the average minimal sizes of E.superba are appreciably higher in the former than in the latter area. This is attributed to milder climatic conditions and better food supply in the South Georgia area as compared to Bouvet Island. The differences in the growth and maturation rates of E.superba between these two areas persist with a change of climatic epochs. During the warmer climatic epoch maturation in both areas begins earlier and stops later than during the colder epoch. Two spawning peaks are observed during the warmer and one peak during the colder epoch.
