Nope. I know my dealer and know where they came from. There are some guys that will also have a cooler full of shrimp mixed with ice and water. They throw in a little bleach if the shrimp get old. Later this month and into September they'll be guys that use a cast net in the sounds to get shrimp. You can buy head on medium shrimp for $2 a lb. I buy some and freeze them for bait.Be careful of buying that "Fresh off the boat" shrimp from the guy in the parking lot. I read an article by a guy who went around buying shrimp from those guys and did DNA tests on the "fresh" shrimp he claims to have caught that morning. About 2/3 of them were Asian shrimp that were thawed out and thrown in a cooler.
