Laboratory observations over a 6-year period were made on the intermoult period (IP), changes in body length (BL) and maturity of 3 female and 3 male krill brought from Antarctic water to Australia. While the IP was stable over the period (range of individual means; 25.6-29.6 days), both BL and maturity changed greatly from one specimen to the next.
