Live freshwater shrimp are native to many waters in the south and central us. All fish eat them and they reproduce in great numbers, They hide in the grass to keep away from the fish. When I was a kid and didn't have money to buy bait I had to catch my own. I would use a small mesh net to catch shrimp in the shallow water to fish with, Great bait, The get into the breeding ponds and holding ponds and sometimes into the minnow bucket,
