    Abstract

    Between year variability of krill year class success and recruitment during the 1975-1994 period are described based on data from German expeditions and US AMLR cruises in the Elephant Island area. Recruitment indices based on the relative abundance of the 1+ year class during each year indicate good recruitment of the 1980/81, 1985/86, 1987/88 and 1990/91 year classes; exceedingly poor recruitment occurred for the 1976/77, 1982/83, 1983/84, 1988/89 and 1991/92 and 1992/93 year classes.
