Prey orientation in piscivorous brown trout

Journal of Fish Biology, 1996
Piscivorous brown trout Salmo trutta change their feeding behaviour depending on prey species, prey size and number of prey eaten. In trout which had eaten fish recently, most had one fish in their stomach, but up to 16 prey fish were found. Individuals of the small‐sized minnow Phoxinus phoxinus were swallowed chiefly tail first, whereas individuals ...

Triploid progeny from a female Atlantic salmon × brown trout hybrid backcrossed to a male brown trout

Journal of Fish Biology, 1996
A female Atlantic salmon × brown trout hybrid was backcrossed to a male brown trout. Electrophoretic analysis of diagnostic enzymes showed that the progeny were triploid. However, a few individuals were partially diploid.

Infection of brown trout with Diphyllobothrium dendriticum procercoids

International Journal for Parasitology, 1997
The aims of this experimental study were to develop a practical method of controlling the number of Diphyllobothrium dendriticum procercoids delivered to a fish host; to examine the effect of different procercoid doses (3, 7 and 15) on the plerocercoid level in fish; and to examine the potential mortality caused by plerocercoids.

Cerebellar Regulation of Sensorimotor Activity in Brown Trout

Brain, Behavior and Evolution, 2002
Evoked field potentials were recorded from the mesencephalic (‘optic’) tectum, cerebellar corpus, midline rhombencephalon, and spinal cord of decerebrated brown trout in response to single electrical shocks given to an optic nerve. Evoked responses were also recorded from the rhombencephalon and spinal cord following stimulation (singly and with trains)

The brown trout and quantitative ecology

1994
Abstract Most readers must have seen a brown trout, if only as one about to be cooked or eaten. They should have noted several features that facilitate manoeuvrability and sustained swimming (Fig. 1.1): a streamlined body covered with overlapping scales; single dorsal and anal fins to prevent rolling and yawing; paired pectoral and ...

Growth and energetics of brown trout

1994
Abstract The literature on fish energetics and growth has increased markedly during the last 20 years and has been summarized in several excellent reviews, mostly as chapters in larger, multiauthored books (Webb 1978; Brett and Groves 1979; Braaten 1979; Elliott 1979, 1981, 1982; Fischer 1979; Ricker 1979;Ursin 1979; Cho et  al.
