Black Sea Bass

In the Summer of 2010 I was accepted into the Minorities in Marine and Environmental Sciences (MIMES) program at the South Carolina Department of Natural Resources Marine Resources Research Institute.  


This program was pivotal in my development as a scientist. Under the mentorship of Dr. Joseph Ballenger (pictured above) and Dr. Marcel Reichert, I spent the summer conducting a life history update on an overfished species, Centropristis striata (black sea bass). I was responsible for aging over 1,000 otoliths and analyzing a fisheries database of over 30,000 sample points for the species.

    I started the program knowing little about the species and would often spend my weekends researching its life cycle, as well as conducting the necessary lab work for my project. The work was challenging, tedious, and towards the end of my stay, very rewarding.

 I found that my mentors’ supportive nature was the highlight of the program; they helped me formulate research questions and methodologies, in addition to improving my professional communication skills through scientific reports and presentations. Their guidance, combined with my introductory biology course at UVI, led me to wonder how fishing pressures may have affected the size at maturity of C. striata over a 30-year period.

    We hypothesized that fishing pressures might account for the significant decrease in size and age of reproductive fish. In my mind, this result reinforced the theories of evolution and artificial selection.

An Otolith


  1. Confirmed Annual Deposition of Otolith Layers - Fish otoliths supposedly create layers annually. However, the last confirmation of this for C. striata occured in the 1990s and had a small sample size (n=5). Through my measurement of 1,288 otoliths and their rings, we were able to confirm that annual rings were created.
  2. Updated Black Sea Bass Life History - Through analysing the 30,000+ data set we were able to update the life history of C. striata. We determined the average age at sexual maturity, the month of spawning, the age to size relationship, and the time period at which these fish switch gender.
  3. Wrote a Report- As part of the program I wrote a report on my work that summer. Please feel free to view it!
