Thermoregulatory behavior of brown trout, Salmo trutta

Hydrobiologia, 1979
Brown trout, Salmo trutta, were allowed to thermoregulate individually in an electronic shuttlebox. Pooled data for 6 fish showed a diel pattern of preferred temperature, with a diurnal minimum of 10.3°C, an early nocturnal maximum of 13.7°C, a less pronounced mid-scotophase minimum of 11.7°C, and a secondary dawn maximum of 12.8°C, in a somewhat ...

Explorative behavior increases vulnerability to angling in hatchery-reared brown trout (Salmo trutta)

, 2014
Animals, including fish, display individually consistent behavioral differences that may affect an individual’s vulnerability not only to predation, but also to fishing. Compared with complex natural environments, plain hatchery environments might induce

Effect of Temperature on gametogenesis and gamete quality in brown trout, Salmo trutta.

Journal of Experimental Zoology. Part A: Ecological Genetics and Physiology, 2013
During the prespawning and spawning season experimental groups of +2 year male and female brown trout, Salmo trutta, were kept under natural photoperiod and at three temperature regimes, a naturally fluctuating one with an average temperature of 7.4 ± 4 ...

A radio telemetry study of the migration of Atlantic salmon (Salmo salar L.) and sea trout (Salmo trutta trutta L.) in the upper Rhine

Hydrobiologia, 1998
Atlantic salmon disappeared from the Rhine River in the mid-fifties when pollution and canalization of the main course of the river blocked access to their spawning areas. After water quality improved in the 1980's, a reintroduction program was begun in the French upper Rhine basin in 1992. To better define the difficulties encountered by the returning

Trophic interference by Salmo trutta on Aplochiton zebra and Aplochiton taeniatus in southern Patagonian lakes.

Journal of Fish Biology, 2013
The length and mass ratio, diet and isotopic composition of Aplochiton zebra and Aplochiton taeniatus inhabiting a Salmo trutta-invaded and a S. trutta-free lake in southern Patagonia were compared. Results indicate that S.

Interactions between ecto- and endoparasites in trout Salmo trutta

Veterinary Parasitology, 2002
Trout fry were experimentally infected with endoparasites (Anisakis sp.) and/or ectoparasites (Gyrodactylus derjavini). During the following 3 weeks the infection level of G. derjavini was significantly lowered in fish infected with live anisakids compared to fish injected with physiological saline, a corresponding amount of Anisakis protein sonicate ...

Breaking the speed limit — comparative sprinting performance of brook trout (Salvelinus fontinalis) and brown trout (Salmo trutta)

, 2013
Sprinting behavior of free-ranging fish has long been thought to exceed that of captive fish. Here we present data from wild-caught brook trout (Salvelinus fontinalis) and brown trout (Salmo trutta...
