Costco's U-20 Farm Raised Black Tiger Shrimp are exceptionally large, whole raw shrimp sold by the pound at the seafood counter. The "U-20" designation means there are under 20 shrimp per pound, making these among the largest commercially available shrimp sizes — ideal for impressive presentations, grilling, and dishes where a meaty, satisfying bite is desired.

Black tiger shrimp (Penaeus monodon) are the largest species of farmed shrimp in the world, recognized by their distinctive dark stripes across a grayish-blue shell. Previously frozen for freshness and thawed in-store, these shrimp deliver a rich, slightly sweet flavor with a firm texture that holds up well to grilling, stir-frying, sautéing, and broiling. Commonly sourced from aquaculture operations in Southeast Asia and South Asia, including Thailand, Vietnam, and India.

These shrimp are high in lean protein and naturally low in fat and carbohydrates. A typical serving of raw black tiger shrimp provides approximately 80–90 calories per 3–4 oz portion, with around 18–20g of protein and minimal fat and carbohydrates.
