Bottom or midwater: alternative foraging behaviours in adult female loggerhead sea turtles (2007, background): “Two oceanic loggerheads (610 and 830mm straight carapace length) in the central North Pacific showed deeper dives and clear diel patterns in their depth utilization: 80–90% of their time at depths o40m during the day and 80–90% shallower than 20m at night (Polovina et al., 2003).”
Circle hook effectiveness for the mitigation of sea turtle bycatch and capture of target species in a Brazilian pelagic longline fishery (2010, background): “For instance, in the Hawaii-based longline fishery, shallow sets (o100m) were banned for parts of 2001 to 2004, which eliminated captures of shallow-dwelling loggerhead sea turtles (Caretta caretta) (Polovina et al., 2003).”
Effects of eliminating shallow hooks from tuna longline sets on target and non-target species in the Hawaii-based pelagic tuna fishery (2009, methodology): “…new experimental technique reported in this study would also significantly reduce longline–turtle interactions because electronic tagging studies reported marine turtles to spend the majority of their time in the upper 100 m of the water column (Polovina et al., 2003, 2004; Swimmer et al., 2006).”
Migration routes and foraging behaviour of olive ridley turtles Lepidochelys olivacea in northern Australia (2007, methodology): “These localised and aggregated foraging records differ from the 7 Endang Species Res 3: 1–9, 2007 wide-ranging foraging records in the Pacific (Byles & Plotkin 1994, Plotkin 2003, Polovina et al. 2003, 2004).”
Reducing sea turtle by-catch in pelagic longline fisheries (2006, background): “Olive ridley (Lepidochelys olivacea), green (Chelonia mydas), hawksbill (Eretmochelys imbricata) and Kemp’s ridley (Lepidochelys kempii) turtles are also captured (Ramirez and Ania 2000; Polovina et al. 2003).”
Western Mediterranean immature loggerhead turtles: habitat use in spring and summer assessed through satellite tracking and aerial surveys (2005, background): “Detailed information about habitat use by the loggerhead turtles subject to this catch is urgently required to regulate fisheries and to reduce their impact on this species (Polovina et al. 2000, 2002).”
Young sea turtles of the pelagic Sargassum-dominated drift community: habitat use, population density, and threats (2012, background): “The epipelagic zone is also deeper than the principal distribution within the water column reported for juvenile loggerheads larger than those in this study (Bolten 2003b, Polovina et al. 2003).”
Pelagic habitat characterization of loggerhead sea turtles, Caretta caretta, in the North Pacific Ocean (1997–2006): Insights from satellite tag tracking and remotely sensed data (2008, methodology): “The subsurface aspect of pelagic habitat will also be investigated, since pelagic diving behavior is common (Polovina et al., 2003), and diving behavior can be a critical component of habitat selection behavior in pelagic organisms (e.”
An overview of loggerhead sea turtle (Caretta caretta) bycatch and technical mitigation measures in the Mediterranean Sea (2010, background): “Loggerhead sea turtles spend most of their time at less than 40 m and they do not dive deeper than 100 m (Polovina et al. 2003).”
Diving behavior and delayed mortality of olive ridley sea turtles Lepidochelys olivacea after their release from longline fishing gear (2006, background): “…swordfish Xiphias gladius, mahimahi Coryphaena hippurus or yellowfin tuna Thunnus albacares, although sea turtles are occasionally caught by deep set (>100 m) longline gear targeting fish of high commercial value fish such as bigeye tuna T. obesus (Ferreira et al. 2001, Polovina et al. 2002).”
