Growth and maturation of Euphausia superba Dana in northern areas of its distribution range (with reference to South Georgia and Bouvet Island areas)
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 ... maturation in both areas begins earlier and stops later than during the colder epoch. Two spawning peaks are ...
