As natural resource managers, we usually want to be somewhere in the middle\u2014a \u201csweet spot\u201d where people can benefit from the resource, either commercially or recreationally, while we ensure that enough fish are protected to support a healthy ecosystem.<!--more--><\/p>\n<p>&nbsp;<\/p>\n<p><strong>Location, location, location\u00a0<\/strong><\/p>\n<p>To a degree, finding that perfect balance depends on where the fish pass their time.<\/p>\n<p>Maryland is home to many <em>marine migratory species<\/em> that swim through other states\u2019 waters and even out into federal ocean waters (beyond three miles from shore.) For example, striped bass can travel as far north as Maine and south to North Carolina every year before returning to the Old Line State in the spring!
