Fish & Fluid Dynamics

Our project revolved around the breeding habits of two fish; the regal angelfish and the cubera snapper. We built an apparatus to recreate the flows generated by the aforementioned fish during mating. Then we collected date on the stirring efficiency of the flows by placing two different colors of plastic beads in the vortices.

We analyzed the data to determine the effect of the generated flows on the stirring efficiency of the beads. The data were then compared to numerical models created in MATLAB to see how well our numerical models represent the actual vortices. This project led to a better understanding of fish breeding habits as well as the effects of vortices on stirring efficiency.
