Maryland Fishing Report – July 9​​​​

The peak of the summer season is here and a time for vacations, relaxing on the water, and of course, fishing.​
As a reminder, striped bass fishing of any kind will be off limits in the Chesapeake Bay and its tributaries from July 16-31. This annual summer break for our state fish helps protect them during the high water temperature and low oxygen conditions of the hottest part of summer, when the stress of catch-and-release fishing can cause a higher mortality rate.
