“…Periods of recovery are generally required following tagging before normal behavior resumes although schooling tendencies may minimize IPRB in species such as bluefin tuna (Hoolihan et al, 2011). Schooling also occurs in albacore (Cosgrove et al, 2014b;Goñi et al, 2011) but the diminutive size of tagged albacore (<20 kg) (Cosgrove et al, 2014a) is likely to be a major factor influencing IPRB and susceptibility to predation. Pre-predation deployment periods were ≤2.5 days in all cases compared to a mean deployment period of 54 (±36 SD) days for the 5 non predated fish (Cosgrove et al, 2014a).…”

This suggests that albacore were more prone to predation in the period immediately post-tagging as they recovered from the tagging procedure.…”

“…Tags were programmed to detach and float to the surface after a period of 9 months, or taking cognisance of potential mortalities, if depth exceeded 1000 m or failed to alter by more than 5 m over 4 days. Tag leaders consisted of stainless steel dart heads measuring 34 mm × 8 mm or plastic umbrella dart heads with 200 lb test nylon kept short at around 60 mm overall length (Cosgrove et al, 2014a). The three predated fish were originally released in continental shelf break areas off the southwest coast of Ireland and the northwest coast of Spain (Fig.…”

“…However, some fish species and age groups may not be suitable candidates for carrying PSATs because of the relatively large size of the tag and consequent energy cost to the study animal (Grusha and Patterson, 2005). Approximately 33% smaller than originals, a new generation of recently developed mini-PSATs has facilitated satellite tracking experiments on a range of smaller species such as striped bass (Morone saxatilis) (Graves et al, 2009); eels (Anguilla Anguilla; Anguilla rostrata) (Aarestrup et al, 2009;Béguer-Pon et al, 2012); juvenile Atlantic bluefin tuna (Galuardi and Lutcavage, 2012); salmon (Salmo salar) (Lacroix, 2013) and albacore tuna (Thunnus alalunga) (Cosgrove et al, 2014a).…”

“…Migration over 1,000 km mostly is involved by seasonal migration (Cosgrove et al, 2014). Tuna seasonal migration is caused by seasonal oscillation (El Nino and La Nina) characterized by a difference sea surface temperature (Syamsuddin et al, 2013).…”

This study was highlighted the contenxt of albacore's number catch, swimming layer and subsurface oceanographic variables (SSOV) at Eastern Indian Ocean include temperature, dissolved oxygen, salinity, nitrate, phosphate and silicate. Hopefully the information would be useful for the longliners to understand the ALB behaviour, environment and the best techniques on how to catch this fish. Data in this study were based on the Research Institute for Tuna Fisheries (RITF) observer program in Benoa from 2010-2013. Data analysis was base on primary data and secondary data. Primary data are albacore's (ALB) swimming layer data which are measured by minilogger. Secondary data is SSOV data which extracted from World Ocean Atlas 2009 (WOA09). The results show that the optimum catch of albacore occurred at depth of 118 to 291 m with the average temperature between 12.41-20.47°C, dissolved oxygen 3.24-4.68 ml/l , salinity 34.78-35.01 psu, nitrate 6.78-17.50 µ mol/ l, phosphate 0.62-1.27 µ mol/l and silicate 10.06-24.77 µ mol/l. The highest catch of ALB was mostly at depth of 156 m (hook number 2 and 11) with the average temperature 18.71°C, dissolved oxygen 4.68 ml/l, salinity 34.78 psu, nitrate 10.71 µ mol/l, phosphate 0.86 µ mol/l and silicate 15.95 µ mol/l. The highest influence of swimming layer and sub-surface oceanographic variable to the number of ALB catch happened at depth of 291 m of ALB swimming layer with coefficient correlation (r) of 0.934 and determination coefficient (R 2 ) of 0.872. The lowest influence of swimming layer and sub-surface oceanographic variable to the number of ALB catch happened at depth of 156 m of albacore swimming layer with coefficient correlation (r) of 0.528 and determination coefficient (R 2 ) of 0.279.The relationship between swimming layer and sub-surface oceanographic variable on catch of ALB tuna was low (<0.500).
