Mohammad Ashraful Alam's Doctoral Scholarly Seminar
Mohammad Ashraful Alam, PhD candidate in Fisheries and Wildlife Science, will present Hypoxia in Great Lakes with Special Emphasis on Yellow Perch (Perca flavescens) for his Doctoral Scholarly Seminar.
Hypoxic events, or low dissolved oxygen (DO) conditions, are common natural phenomenon all over the marine and freshwater environments. Hypoxia has been shown to affect the wide array of physiological processes in fish, including growth, reproduction and the embryonic development. However, hypoxic events in the Great Lakes and how this affects the embryonic development of Yellow Perch have been rarely documented in literature. We conducted serial of experiments in the laboratory under three different concentrations of dissolved oxygen - hypoxia, 3-4 mg DO/I (H); moderate-hypoxia, 5 mg DO/I (MH) and normoxia, 7-8 mg DO/I (N) in replicates of four at 16.8±0.4° C. Overall. the results indicated that hypoxic conditions below 3.5 mg DO/I (35% saturation at 16° C) have a profound negative impact on the embryonic development and survival of Yellow Perch.
The seminar will begin at 1:50 p.m. in 333D Kottman Hall.
