Species, production method and product form come before comparison
Shrimp and prawn names can cover multiple saltwater and freshwater species. Wild-caught white or pink shrimp, farmed whiteleg shrimp, black tiger shrimp and freshwater prawns have different biological identities, supply systems and evidence requirements. NOAA's chilled-or-frozen shrimp standard separately identifies heads-on, headless, peeled, deveined, tail-on and tail-off market forms; it also separates fresh, thawed, individually frozen and solid-pack products and raw, blanched and cooked styles. Atlas retains those fields before comparing volume, quality, price or trade evidence.
