Abstract Details

2014, Master of Science, Miami University, Zoology.
Fish are important mediators of nutrient cycling, having direct effects via nitrogen (N) and phosphorus (P) excretion. The relative rates at which N and P are excreted are strongly influenced by the stoichiometry of fish bodies, the resources they consume and their growth rates. However, little is known about the stoichiometry of fish during early developmental stages, when the demand for phosphorus for bone development is likely to be great. I investigated how light and nutrients impact N and P excretion rates of fish (bluegill) during early ontogenetic development. Larval bluegills were raised in mesocosms with realistic food webs, in a factorial design with two levels of light and nutrients. Light and nutrients influenced excretion rates through effects on bone development and food quality, but light and nutrients had few effects on body stoichiometry, which was a function of age. Growth rates influence the timing of ontogenetic shifts in stoichiometry.
