However, in situ
measurements of zooplankton respiration remain difficult to carry out
in practice. Capturing a natural zooplankton community and isolating
it in good physiological condition in a simulated in situ environment
long enough to make a physiological and ecologicallymeaningful respirationmeasurement,
challenges the possible. Hence, the drive to develop
biochemical indices of respiration. The activity of the respiratory
electron transport system(ETS), theoreticallymeasures potential respiration
(ϕ) and since the early work of King & Packard, 1975 and Finlay
et al., 1983 its relationshipwith respiration has been shown to be better
than the Kleiber relationship between respiration and biomass (Packard
& Gómez, 2008). Accordingly, we use ETS activity to calculate respiration
thereby reducing the problems associated with incubation of zooplankton
in a controlled environment (Gómez, 1991).
