The pattern of swimming of postlarval shrimp maintained under constant con- ditions within two current chambers (I and II) for three days following their collection from nature. Swimming was recorded in terms of the numbers of individuals which moved in an up or downstream direction during two minute observation periods made at 30 minute in- tervals. The times of day and night in nature are represented by the open and transverse bars, respectively, at the top of the figure. Time of low and high tide in nature are indicated by the open and shaded arrows, respectively. (See text for description of constant conditions.).
