Colleagues (Emmanuel Frimpong, Kyle Strom, and Hosein Foroutan) from VA Tech and I (University of Richmond) plus a half platoon of graduates students are conducting a collaborative research: An interdisciplinary approach to understand selfish parental care of egg and larvae in mixed-species communal nest breeding freshwater fishes. Yesterday (21 May 2021) was the first day that we observed nest construction and spawning in Nocomis leptocephalus, Bluehead chub and its nest associates. Water temperature was 16.5 C at 1206 hours EDT. We filmed behaviors for four hours using three cameras (one from above the surface of the water to give context to all behaviors and two underwater cameras for details of behaviors). Below is a short, low resolution clip of HD video of behaviors of fishes over nests. Stay tuned.
