Predation Threat Causes Stress in Fish
 By, Joshua Brower, M.S. Student

          Stress is a part of everyday life, even for animals.  Everyone has been stressed out and has firsthand experience with how stress can affect our mood, appetite, and how we deal with others.  Animals can have similar reactions when stressed and experience many stressors ranging from extreme temperature to antagonistic encounters with other animals.  When exposed to stressors animals may change their behavior by moving more cautiously or seeking shelter.  Animals will also experience a physiological stress response that can affect metabolism which, in conjunction with behavioral changes, can have a negative impact on the animal’s well being.  Many recent studies have tried to understand how human impacts affect animal stress, however, the effects of natural stressors in the wild are still poorly understood.  Certainly, one cause of stress in the wild is the threat of predation.  Like many organisms, fish are most vulnerable to predation during juvenile life stages.  The juvenile stage, for example, is also important developmentally; stress during this time may have important consequences to fish later in life.  My research focuses on the effects of stress due to predation threat on juveniles of the local species the giant kelpfish.

          My research is focused on the effects of stress due to predation threat on juvenile fish.  Specifically, I use kelp bass and juvenile giant kelpfish as a model predator-prey system to examine how kelpfish respond to the stress of predation threat both behaviorally and physiologically.  I am able to quantify the physiological stress response to various experimental treatments by measuring the amount of the hormone cortisol kelpfish produce.  I am pursuing these research interests through a series of laboratory and field experiments based at CMIL.  
 

A day in the life...

          My day as an ecologist can vary greatly depending on the task at hand.  Some tasks require me to work with aquaria at the marine lab, or SCUBA dive to collect fish, while others bring me to our laboratory on campus to conduct chemical analyses of the fish from my experiments.  When I am running experiments my day starts early (generally an hour before sunrise) because the kelp bass that I use in my experiments are most active at dawn and dusk. Maintaining holding tanks to keep fish alive and healthy for my experiments is also an important part of my daily routine.  Fish must be fed every day and tanks cleaned once to twice a week.   I enjoy how each day of research brings new challenges to think through and overcome.

Giving back through science

          Underprivileged children have few opportunities to experience the outdoors and frequently view science as inaccessible.  I have seen the positive effects of bringing youth into the outdoors, firsthand, through volunteering with Outdoor Outreach (OO).  OO is a San Diego based organization with the mission “to empower at-risk and underprivileged youth to make positive, lasting changes in their lives through comprehensive outdoor programming.”  I have found it very fun and rewarding to teach OO participants about local environments through activities like hiking, snowboarding, kayaking, and even learning to swim.  There are many great outreach organizations in San Diego, get out there and volunteer!  You never know what you might gain in the process.
