Annapolis Science Cafe @ 49 West: “The Magothy River Index and the Yellow Perch Dilemma”, by Paul Spadaro and Sally Hornor, Magothy River Association

Thursday, May 25, 2023, 6:00-7:15pm ET

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. We 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 and we will look at these efforts. For the past ten years we have 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. The MRA contends that this population is sustainable in the Magothy while the MD Dept of Natural Resources does not concur. Please join us for Sally Hornor’s and Paul Spadaro’s presentation on the state of the Magothy River and the yellow perch dilemma in the Magothy River. We hope you will come in person, but zoom info is available too; if interested in zoom or other questions, email annapoliscafesci@gmail.com
