Abstract:
This study was conducted at Setiu Wetland, Terengganu. Mud crab, genus Scylla
species are commercially important mangrove resident found within the mangrove
area. The movement patterns were studied through the tag return by using mark
release-recapture technique. The crab samples were tagged by Fluorescing Visible
Implant Elastomer (VIE) tag and released at the same captured stations for one week
interval before the next sampling. The crab samples were measured, identified for
mud crab species and recorded. Three species were present and dominated by S.
olivacea and S. paramamosain. Only a few samples of S. tranquebarica were
obtained. The movement of S. olivacea was more restricted and have high tendency to
inhabit certain area for a period of time. As for the S. paramamosain, their movement
was free-ranging and rarely inhabits the same area for a long period.
