The Hatfield Marine Science Center continues to hold its popular Science on Tap speaker series.  The events can’t take place in a pub in pandemic conditions, so you have to pour your own, but on the upside, they are online and can be enjoyed by people throughout the state.

Next up, on Tuesday, Feb. 15, at 6 p.m. is Su Sponaugle, Professor in Oregon State University’s  Department of Integrative Biology, based at the Hatfield Marine Science Center.  Her topic: “Peering into the world of larval fishes: tools and tales.”

Dr. Sponaugle is a marine ecologist and fisheries oceanographer who conducts basic and applied research on the ecology of marine fishes and the dynamics of their early life history stages. Her lab is especially interested in the processes underlying the growth, survival, and dispersal of early life stages, leading to successful settlement and recruitment to the benthic populations. The overarching goal is to better understand the events occurring in the pelagic larval stage that influence population replenishment and connectivity. The data we collect are not only relevant to ecology and oceanography, but also are useful for quantifying overall population replenishment, designing and evaluating marine reserves, and interpreting future environmental changes.

Her description of the talk:

“Most marine fishes begin life as miniscule larvae that spend time in the pelagic ocean. This early life stage is particularly important as small changes in the survival of larval fishes can lead to large fluctuations in adult populations. Yet, it is very challenging to study these stages to understand what contributes to their survival because larvae are not only tiny and transparent, but they also occur rather diffusely in the large ocean. This combination of characteristics necessitates the use of unique research tools. Come and find out how we use several integrated tools to identify the oceanographic processes that influence growth and survival of young fishes. Five “fish tales” will illustrate how this approach helps us peer into the secret life of young fishes.”
