Bigeye Tuna (Thunnus obesus) behaviour and phisiology and their relevance to stock assessments and fishery biology (2005, background): “But the extreme tolerance of low ambient oxygen in bigeye tuna seems incongruous in light of tunas’ elevated metabolic rates (Dewar and Graham 1994, Korsmeyer and Dewar 2001).”
Fast versus slow growing tuna species: age, growth, and implications for population dynamics and fisheries management (2017, background): “In fact, tunas have mastered each step in the oxygen cascade from the gills to the mitochondria to enhance oxygen uptake and flux (Brill and Bushnell 2001; Korsmeyer and Dewar 2001).”
Age and growth of longtail tuna (Thunnus tonggol) in tropical and temperate waters of the central Indo-Pacific (2010, background): “These fish are, therefore, likely to have lower standard metabolic rates (Brill, 1994; Korsmeyer and Dewar, 2001) and slower rates of gastric evacuation (Temming et al., 2002) and, hence, lower daily feeding rations, which may explain their slower growth and lower rates of natural mortality (Pauly,…”
Temperature and dissolved oxygen requirements for survival of yellowfin tuna, Thunnus albacares, larvae (2011, background): “The fusion of gill lamellae, a specialization for ram ventilation (Korsmeyer and Dewar, 2001), begins to develop at 2–3 cm in yellowfin tuna (N.”
