Daytime burrowing behavior of penaeid shrimp was examined in a laboratory study. Over all experiments, 77.5% of brown shrimp and 21.4% of white shrimp burrowed. Less than half of brown shrimp population is likely susceptible to capture in trawls. Salinity and substrate type likely affect net catch efficiency for brown shrimp. Most (97%) white shrimp emerged from burrows after disturbance and were susceptible.
