Febrile responses of goldfish Carassius auratus (L.)to Aeromonas hydrophila and to Escherichia coli endotoxin

Behavioral fever in ectothermic vertebrates

“…Up to date, behavioral fever has been described in all groups of ectothermic vertebrates including reptiles (Bernheim and Kluger, 1976a,b;Burns et al, 1996;do Amaral et al, 2002;Hallman et al, 1990;Kluger et al, 1975;Merchant et al, 2007Merchant et al, , 2008Monagas and Gatten, 1983;Muchlinski et al, 1995;Ortega et al, 1991;Ramos et al, 1993;Vaughn et al, 1974), amphibians (Casterlin and Reynolds, 1977;Kluger, 1977;Murphy et al, 2011;Myhre et al, 1977;Richards-Zawacki, 2010;Sherman et al, 1991), fish (Boltaña et al, 2013;Cabanac and Laberge, 1998;Covert and Reynolds, 1977;Grans et al, 2012;Reynolds, 1977;Reynolds et al, 1976Reynolds et al, , 1978 but also in invertebrates (Campbell et al, 2010;Elliot et al, 2002) and newborn mammals, which in response to bacterial pyrogens are unable to develop fever physiologically but do so behaviorally (Satinoff et al, 1976). However, there have been some contrasting data showing that injection of pyrogens, killed bacteria or parasites in some species of lizards (Don et al, 1994;Hallman et al, 1990;Laburn et al, 1981;Muchlinski et al, 1995;Ortega et al, 1991;Schall, 1990), turtles (Zurovsky et al, 1987b), snakes (Burns et al, 1996;Zurovsky et al, 1987a) and fish …”

Because of the relatively low sensitivity of fish and toads to LPS, the dose used to induce behavioral fever in these animals (toad:…”

Stress in Aquaculture Hatcheries: Source, Impact and Mitigation

“…Changes in temperature preferences (Reynolds et al, 1978) and infection with pathogens (Tsai and Hoh, 1995) has also been documented. Stress can interfere with learning responses (Schreck et al, 1997), however there is little information that directly relates the effect of stress on learning ability or memory of fish.…”
