Title: Potential Positive Effects of Hypoxia on Fish Habitat Quality

Speaker:  Dr. Marco Costantini, NRC Associate, NOAA Great Lakes 
Environmental Research Laboratory

Date: Tuesday December 19

Time: 1030 AM

Abstract
Bioenergetics models, designed for processing spatially-explicit 
environmental and biological data, were used to estimate the effects of 
hypoxia on potential growth and habitat quality of fish predators; i.e., 
walleye in Lake Erie and striped bass in Chesapeake Bay. In both 
systems, both positive and negative effects of hypoxia on predators were 
observed. Specifically, hypoxia reduces potential growth in deoxygenated 
waters and enhances predation efficiency/prey vulnerability by forcing 
prey in oxygenated surface waters. In Lake Erie, our results suggest 
that the recent reappearance of hypoxia in the central basin may only 
minimally influence the walleye habitat quality. In Chesapeake Bay, our 
findings have led us to speculate that hypoxia actually may indirectly 
benefit striped bass by increasing susceptibility of their fish prey, 
and that hypoxia may initially have played a role in the recovery of 
striped bass during the mid-1980s. Examples of how the interplay between 
the hypoxia-driven effects could impact the management of economically 
and ecologically important fish stocks are given.
