Café Scientifique: The Magothy River Index and the Yellow Perch Dilemma
May 25, 2023 at 6:00 pm - 7:15 pm
The Magothy River Index is calculated each year, providing a perspective of the well-being of the river based on three criteria: the amount of submerged aquatic vegetation, the amount of dissolved oxygen in the deepest water and water clarity. The speakers will discuss this annual review for the recent past and present data for 2022, which shows an improvement in water quality.
The Magothy River Association is an all-volunteer group of residents who have worked on aquatic grass restoration as well as oyster reef restoration. For the past ten years MTA has been involved with the study of the yellow perch population in the river, documenting annual spawning events which produce egg sacs as well as seining for larval fish downstream from the spawning grounds. MRA contends that this population is sustainable in the Magothy while the Maryland Department of Natural Resources does not concur.
Speakers: Paul Spadaro, President, Magothy River Association; and Sally Hornor, Ph.D., Professor Emerita, Anne Arundel Community College and MRA Vice President.
