We investigated ontogenetic variations in dry mass and nucleic acid contents of the planktonic crustacean
Artemia salina. Individual contents of DNA and RNA increased exponentially with incubation day and developmental
stage, except for newly-hatched nauplii. High variability was found in the temporal and ontogenetic patterns of dry
(DW) and ash-free dry weights (AFDW) due to the mixture of different ages and stages, and thus RNA/DNA ratios
were not significantly associated with weight-specific growth rates
