Pop-up satellite archival tags (PSATs) and conventional dart tags were used to study the movement patterns and habitat preference of tuna, billfish and tuna-like fish in eastern Taiwan. The 2 yellowfin tuna tagged at set net, migrated a round route outside the eastern waters off Taiwan. Pooled archival data downloaded from the PSATs showed that yellowfin tuna spent 48% of their time in the upper uniform mixed above 50 m. Diving depth ranged from 0 to 312 m and ambient water temperature from 17.5°C to 25.2°C. One black marlin tagged by harpooner, migrated a left round route to the Haina Island (Southern China). Black marlin spent 79 % of their time in the upper uniform mixed above 50 m. Diving depth ranged from 0 to 136 m and ambient water temperature from 18.2°C to 28.8°C. Linear displacement was 1,800 km from deployment to pop-up locations at the East China Sea. 51 common dolphin fishes were tagged with conventional plastic dart tag at set net, 10% (n= 5) were all recaptured at the northern location off deployed area. It revealed the common dolphin fish migrate along eastern waters off Taiwan from south to north during summer season.
