The ecological and evolutionary aspects of thermoregulation behavior on fish

Effects of Temperature in Juvenile Seabass (Dicentrarchus labrax L.) Biomarker Responses and Behaviour: Implications for Environmental Monitoring

“…As a result, temperature has been identified as one of the most vital abiotic factors for fish, since it can potentially affect all the metabolic, physiological and also ecological aspects and behavioural tendencies of fish life cycle (Moyle and Cech 2003). In fact, if able to do it, fish species can behaviourally choose a preferred range of water temperatures (thermoregulation behaviour), at which physiological processes, growth, reproduction and survival are optimal (Beitinger and Fitzpatrick 1979;Golovanov 2006), determining their thermal ecological niches (Fry 1971;Magnuson et al 1979). Though, if habitat restriction occurs by thermoregulation behaviour as a consequence of temperature increase, intra-and interspecific competition will increase, leading to ecosystem unbalances.…”

Effects of feeding on thermoregulatory behaviours and gut blood flow in white sturgeon (Acipenser transmontanus) using biotelemetry in combination with standard techniques

“…Thermoregulation in ectotherms is shown to be extremely complex, and numerous reviews have discussed the potential costs and benefits associated with these behaviours (Huey and Slatkin, 1976;Reynolds and Casterlin, 1979;Seebacher, 2005;Seebacher and Franklin, 2005;Golovanov, 2006). It is generally believed that ectothermic animals can benefit from behavioural thermoregulation by avoiding harmful temperatures and by getting some control over metabolic processes, but these behaviours are associated with costs, which in some situations outweigh the benefits making thermoregulation impractical.…”

Recent Occurrences of Opah, <I>Lampris Guttatus</I> (Actinopterygii, Lampriformes, Lampridae), in the Western Mediterranean Sea

“…However, during the night, opahs migrate to shallower waters (about 50 m depth) with higher temperature. This particular behaviour corresponds to the thermoregulation behaviour described by Golovanov (2006). The depth of capture is known for 19 of the 23 records: nine opahs have been observed close to the surface or stranded on a beach, six between 20 and 40 m depth, and four have been caught deeper, between 60 and 200 m depth.…”
