Growth Rate Of Copepods In The San Francisco Bay, Brooke Bemowski, Wim Kimmerer, Toni Ignoffo

STAR (STEM Teacher and Researcher) Presentations

The San Francisco Estuary is a complex ecosystem. A key part of the foodweb are zooplankton crustaceans, specifically copepods. Many fish, especially the endangered delta smelt, rely on copepods as a food source. Measuring the growth of copepods assists in predictions if enough food is available for delta smelt. Traditionally growth rate is measured through lengthy and involved processes. The objective of this research project is to develop an imaging process to analyze biomass of copepods more efficiently. For this research, field samples of copepods were collected and grown over three days. Subsamples were taken and preserved at three predetermined ...
