Physiological thermoregulation in bigeye tuna Thunnus dews*

The bigeye tuna, Thunnus obesus, is distributed in all the tropical and subtropical oceans, occurring between 50 o N and 45 o S in the Atlantic Ocean (COLLETTE; NAUEN, 1983). Juvenile specimens under 50 cm total lenght are found near the surface and are caught mainly by purse seine and handline with mixed shoals of yellowfin tuna ( Thunnus albacares ) and skipjack tuna ( Katsuwonus pelamis ).
(1992), bigeye tuna, which possess retia, undergo physiological and behavioral thermoregulation by changing λ by two orders of magnitude (7 to 12 kg, λ 1 = 3.13×10–2 for cooling, λ 2 = 2.41 for warming). This enables bigeye tuna to equalize surface water and body temperatures in the manner of an ectothermal animal.

Bigeye tuna, Thunnus obesus (Lowe, 1839) is a marine pelagic fish species characterized by large populations and a worldwide distribution (Atlantic Ocean, Indian Ocean and Pacific Ocean) restricted to tropical and subtropical waters (except the Mediterranean Sea) [22, 23].
The k of chum salmon was larger than that of bigeye tuna (Thunnus obesus) by about one order of magnitude for the cooling of the body.

Here we show using telemetered data that free-ranging bigeye tuna (Thunnus obesus) can rapidly alter whole-body thermal conductivity by two orders of magnitude. The heat exchangers are disengaged to allow rapid warming as the tuna ascend from cold water into warmer surface waters, and are reactivated to conserve heat when they return into the depths.

(1992), bigeye tuna, which possess retia, undergo physiological and behavioral thermoregulation by changing λ by two orders of magnitude (7 to 12 kg, λ 1 = 3.13×10–2 for cooling, λ 2 = 2.41 for warming). This enables bigeye tuna to equalize surface water and body temperatures in the manner of an ectothermal animal.
Background. A characterization of an organism’s thermoregulatory ability informs our understanding of its physiology, ecology and behavior. Biotelemetry studies on thermoregulation increasingly rely on in situ body temperature measurements from surgically implanted data loggers.

Introduction. The behavioural ecology behind the migrations and habitat use of marine fishes intrigued scientists from the very first forays of ocean discovery, but our knowledge acquired since then has been very much skewed towards inshore fishes and their habitats.

Data on the depth and temperature preferences of bigeye tuna (Thunnus obesus) derived from archival tags were integrated with data on the spatial and temporal distribution of catches from an eastern Australian longline fishery to investigate the relationship between bigeye tuna behaviour and the fishery.
Here we show using telemetered data that free-ranging bigeye tuna (Thunnus obesus) can rapidly alter whole-body thermal conductivity by two orders of magnitude. The heat exchangers are disengaged to allow rapid warming as the tuna ascend from cold water into warmer surface waters, and are reactivated to conserve heat when they return into the depths.

The bigeye tuna, Thunnus obesus, is distributed in all the tropical and subtropical oceans, occurring between 50 o N and 45 o S in the Atlantic Ocean (COLLETTE; NAUEN, 1983). Juvenile specimens under 50 cm total lenght are found near the surface and are caught mainly by purse seine and handline with mixed shoals of yellowfin tuna ( Thunnus albacares ) and skipjack tuna ( Katsuwonus pelamis ).
