Abstract
The study was undertaken to determine the vertical distribution of immigrating postlarval brown and white shrimp through a large tidal pass during day and night. Samples were taken at two stations in Bolivar Roads Tidal Pass, the major entrance to Galveston Bay, Texas. Average catch of both species was highest in the upper 2 m of the water column at night and at mid-depth during the day. One or the other of these depths, depending on whether sampling occurs during the day or night, would probably yield the most accurate abundance estimate, or the greatest catch-per-unit-effort of postlarvae.
