I used to catch the grass shrimp in the bay areas on cape cod,,, I'd just scoop around the docks where boats where parked and they. Shrimp Woukd always be on the grass attached to docks,,, I'd fill a pal of shrimp and head to my favorite trout ponds and fish,,, Live grass shrimp work crazy good on trout... I suppose you could use them on any fish.. It's almost cheating when it comes to fishing with them,,,I live down south off the Mississippi River now where grass shrimp are no where to be found except maybe the Internet,,,, check there,,, I hear you can find anything on the interent
