Here, five secondary production models are tested by measuring Daphnia magna growth. To provide a range of growth rates, Daphnia were cultured under three different nutrition regimes (yeast, cornflour, and phytoplankton). Length and biomass were monitored daily in three simple time-course experiments to provide the growth rates, which ranged from 0.11 to 0.30 d–1 with secondary production rates of 350–643 µg dry mass d−1. Secondary production was predicted best by the freshwater crustacean-based model of Stockwell and Johannsson (1997). Marine copepod-based marine models were totally unsuitable.||URI:||http://hdl.handle.net/10553/45815||ISSN:||1054-3139||DOI:||10.1093/icesjms/fsr193||Source:||Ices Journal of Marine Science [ISSN 1054-3139], v. 69 (3), p. 421-428|
