stripers and rockfish are the same it just depends on the location/size/season they are being fished for. stripers/rockfish are saltwater fish not freshwater.. they do travel up rivers to brackish/fresh water to give birth. they can not live in fresh water alone. the other thing you could look at would be white bass which are typically freshwater and look similar to striped bass. also on that note there are striped bass hybrids which are striped bass and white bass when mating upstream. I would not keep a striped bass in a tank unless it is huge. i have seen 48" + striped bass while fishing and the same goes for ones held in captivity... since you are in fishing in ches. bay i would go to bass pro in hampton and checkout there display tank. they have multiple bass over 36" in there, they look miserable and that is easily over 1000gal tank.
