Understanding packing density for oysters helps explain why a 5-gallon container often holds about 160 oysters. In the seafood trade, counts are tracked by pieces, and for a typical “medium” size, shucked or shell-on, a practical packing density is about eight oysters per quart. Since five gallons equal 20 quarts, you get roughly 20 × 8 = 160 oysters. This gives a balance between maximizing count and protecting the shells during handling. If the oysters are noticeably larger or smaller, the count would shift, but 160 is the common standard for medium oysters in a 5-gallon container.
