2004 Cooperative Striped Bass Survey

Abnormalities and Fish Health Description

Fish diseases in the Chesapeake Bay and along the coast affect many species of fish and are dependent on a variety of environmental factors. The following are five common anomalies found in striped bass. Not all anomalies are life threatening. Just as you and I can catch a cold, fish can contract a bacterial infection or a virus. If any fish you catch exhibits one or more of the following anomalies, please indicate it in the appropriate area on your survey form.
