Among-year variation in growth of Antarctic krill Euphausia superba based on length-frequency data
(annual estimates for a 30 mm krill in the Elephant Island region ranged from 0.00 to0.17 mm d −1; mean ... wild populations is practically and statistically difficult but crucial for connecting such variation ... to mechanistic drivers and their population consequences. For somatic growth, empirical estimates of ... relied on estimating growth from length-frequency distributions. We developed a general approach for ...
