"Live Food" Experiments Underway!

Our trout are getting their first taste of live food this month, as students ask the question, "Will my trout eat living food?"  Following Scientific Method, students are investigating the response of trout to the presence of living zooplankton, called Daphnia, making careful observations during a five minute experiment. 

Here is an example of initial data.  More will be available shortly!

Daphnia are provided, courtesy of the Nelson Hairston Jr. Lab of Evolutionary Biology at Cornell.  Here's lab manager Lindsay Shafner providing a new batch of these critters.  Our thanks to her, and to Prof. Hairston for their support!
