Ingestion Of Low Density Food Particles By Suspension-Feeding Goldfish, Kristin Edwards Dec 2015

Ingestion Of Low Density Food Particles By Suspension-Feeding Goldfish, Kristin Edwards

Undergraduate Honors Theses

Goldfish (Carassius auratus) are known to be suspension-feeders that use crossflow filtration to filter out extremely small food particles from the water. In this study, I investigated whether goldfish could feed on low-density food particles and also tried to identify any feeding behaviors or morphological traits that could be involved in this mechanism. I conducted feeding experiments with various novel and familiar food types that were followed up by gut content analysis to confirm ingestion of the low-density particles. I also observed and quantified by counting three behaviors associated with this feeding mechanism and performed statistical analyses to look for ...
