Numerous growth rates of copepods and larvaceans have been determined from microcosm manipulations and laboratory incubations in tropical waters from eutrophic to oligotrophic environments. Animal size is an important variable in all cases. For copepod nauplii, growth is related to body size alone. For copepodites, growth is related to body size and to a lesser extent resources (as chlorophyll). In adult copepods, egg production is clearly related to a combination of both body size and resources. In the larvaceans, although body size per se could not be related to growth rate, it was implicated in the ability of resources to limit growth, but only under extreme concentrations of resources. Thus the practice of applying adult growth rates to younger stages, or between species of different sizes, is capable of introducing pronounced biases in estimates of secondary production. Due to such biases, the secondary productivity of tropical marine waters is much greater than currently appreciated.
