Whosits & Whatsits Galore: What do larval fish eat, and who eats them?

20150402_HatfieldGradStudentMiram_HO-4675  Tonight on Inspiration Dissemination, Miram Gleiber (a 1st year PhD student in Integrative Biology) discusses her passion for ‘le poisson’. Working underneath Su Sponaugle and Bob Cowan, Miram first got into the piscine when she was a little girl, investigating tide pools in Victoria, British Columbia. “When you take a scoop of water from the ocean you don’t realize what’s in it,” Miram muses, “… it’s a whole other world.”

Because Larval fish grow up to be reef fish, which are good for biodiversity and tourism, obtaining accurate numbers of wild stock that survive the larval stage and understanding what conditions promote survival is valuable knowledge. The fish first hatch and “hang out” for thirty days in the open ocean before coming back to the reef, during which time they subsist largely on patches of zooplankton and phytoplankton that float around in the open ocean. Miram’s current research at OSU aims to understand how these patches of tiny biodiversity contribute to the growth and survival of the small fishes that eventually make their way into the view of our camera lenses and photo albums, and sometimes to our plates, as well.

About Matt McConnell

Matt McConnell is from Midland, Michigan and received his undergraduate BS in Psychology and Philosophy at Central Michigan University. After graduating he spent several years in North Carolina. Most of this was at UNC working as a medical research lab assistant using mice as model organisms, but some of his work also involved cognitive research with Rhesus Macaques at a Duke University field site in Puerto Rico. Matt currently live in Corvallis, OR where he attends OSU as a graduate student in the History of Science master's program. He is taking Science Education as a related minor, with an emphasis in Free Choice Learning. His interests in History of Science and Science Education meet on the practice of Science Communication. Matt is currently co-host of the weekly radio show 'Inspiration Dissemination', in which graduate students discuss their personal journeys. Inspiration Dissemination is open to all graduate students and airs every Sunday evening at 7pm on 88.7 FM, KBVR Corvallis.
