Vertical profiles of seston food quality and quantity were measured in subalpine Castle Lake for particulate carbon, chlorophyll  a , fatty acids and phosphorus in addition to abiotic parameters including water temperature and dissolved oxygen levels. Field and laboratory incubation experiments were employed to manipulate  Daphnia rosea  growth environments. Sestonic eicosapentaenoic acid (EPA) content was much lower, whereas carbon to phosphorus (C:P) ratios were much higher in the epilimnion compared to the deep-water chlorophyll maximum (16–20 m). In a temperature-controlled incubation,  Daphnia  grew faster when fed seston from the deep-water chlorophyll maximum. In  in situ  cage incubations,  D. rosea  grew fastest in the epilimnion.  Daphnia rosea  in a migrating treatment exhibited intermediate growth rates between the ones for epilimnion and hypolimnion. A projection of  D. rosea  growth rates by growth models without regard to water temperature showed much higher growth potentials in the hypolimnion. However, with inclusion of water temperature, epilimnetic water always gave higher potential growth rates. In this lake, warmer temperatures of epilimnetic water override the higher food quality and quantity provided by the deep-water chlorophyll maximum.
