| Summary: | The pattern of movement of green tiger prawn, Penaeus semisulcatus, was carried out in
Bushehr waters, Persian Gulf, in 2003 and 2004. During this experiment 2571 shrimps, P.
semisulcatus were tagged with green polyethylene steamer tags and released at sea from January
2003 to July 2004. During the open season of shrimps (August and September), 68 shrimps were
recaptured but four of the recaptures were excluded due to inconstancies of information. The
direction of movement of recaptures was mostly to the north west of the release area and to
deeper waters. The majority of recaptures exhibited speed of less than 2 km/day and maximum
speed was recorded at 3-4 km/day. The longest distance of 127 km was performed by a female
during 95 days liberty. In the Persian Gulf the main of sea current is from the Strait of Hormuz to
the Iranian waters, and probably influences the pattern of shrimp movement in the Bushehr area.
