Paul O’Bryant

Paul O'Bryant studies sex determination and sex differentiation in fish, particularly yellow perch and bluegill, examining how genes, hormones, temperature, and rearing conditions (like density and mixed-species culture) influence whether fish develop as male or female. This work has applications in aquaculture, such as producing single-sex fish populations for improved farming outcomes. Students in this area would likely work with molecular techniques (gene expression analysis, siRNA gene silencing) alongside practical fish-rearing experiments.

Publication output has been modest and uneven over the last decade, with gaps in some years followed by a recent uptick in 2022-2025.
