Please check your state's summer flounder regulations. NOAA has continued "conservation equivalency." This means they waived the federal recreational bag limit, minimum fish size, and fishing season, so vessel owners are subject only to regulations for the state in which you intend to land your Summer Flounder.
To see regulations for a particular state, tap the blue location bar at the top of the app, tap "Open Full Screen" at top right edge of map, then zoom in/out and tap the map to set a pin at your desired location, then tap Save. Your state waters should be listed in blue at the top of the screen. Once you tap "Back" at the top left of the screen, you will see the relevant state regulations.
