Local farmers market has 3 different types of shrimp for sale. One is white shrimp. I am assuming this is farm raised and a freshwater shrimp? Second is Tiger shrimp. I am hoping this is saltwater but not sure. Third is shrimp with head, looks like white shrimp again. Kringle took the tiger shrimp with gusto last night. I bought more blue crabs but have separated the claws from the bodies and cut the bodies in quarters. Now I'm curious what the difference is between the Tiger Shrimp and the White Shrimp. I seem to remember the white shrimp being compared to candy for an octopus and that the nutritional value was not that great.
