Authors

Abstract

This research was carried out in Strait of Hormuz in 2020. The present study aimed to
investigate the migration and growth pattern of tagged shrimps in the study area.
Bloodstock shrimps were reared in June (2010). About 50000 juvenile shrimps were tagged
by red color florescent elastomeric tag and released in the estuaries of Tiab, Kolahi and
Koolgan at night in July 2010. Local people were informed through posters describing the
tagging program, as well as articles published in a local magazine. A tagging program film
was broadcasted on local television three times prior to the shrimp fishing season and during
shrimp catch period.
In the catch season, September and November months, 11 tagged prawns (0.022%) were
recaptured. Movement direction of tagged prawns was northwesterly of deeper waters of
releasing areas. Speed was recorded at 0.33-0.33 km/day and tagged prawns were recaptured
46 km from the released locations. The mean (±SD) weight of released banana prawns and the
average weight of the recaptured prawns were1.2±0.2 g and 22.06±4.9 g, respectively. The
growth rate of recaptured prawns was 16-26 g and growth speed was 0.88-1.41 g per week.
In the study area, the major sea current was from the Oman Sea to the Persian Gulf through
Strait of Hormuz probably influencing the pattern of banana prawn movement in Hormozgan
