G.}, journal = {Proceedings of the NIPR Symposium on Polar Biology}, month = {Dec}, note = {P(論文), 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. Reversible modes shown in BL and maturity suggest that neither parameter is a good indicator of chronological age in this animal. Considering the age of krill at the beginning of this experiment (least 1-2 year old) krill lived for 7-8 years, which is considerably longer than the previously hypothesized 2-5 year life span of this animal.}, pages = {56--62}, title = {LONGEVITY OF THE ANTARCTIC KRILL (EUPHAUSIA SUPERBA DANA) BASED ON A LABORATORY EXPERIMENT (Ninth Symposium on Polar Biology)}, volume = {1}, year = {1987} }
